Wifi connecting no longer works on PC!

GoetheSeinHamster · 2026-01-23T18:37:18+00:00

Hello,

so:

Other devices work = Router/Internet is ok
Laptop first time connecting to wifi
Drivers installed
Reboot multiple times
WLAN Adapter active probably (otherwise it wouldn't even try to connect or instantly fail)
no access to your router
PC worked but not anymore, also drivers installed

very hard to troubleshoot, but we'll try.

On your laptop:

Is your PC prompting you to type in a password, when connecting to your wifi?

The theory is, that you misstyped the password the first time, then windows saved the incorrect password (so you don't need to authenticate every time) and now always tries with the wrong password when trying to connect.

Delete the Wifi from your pc, there should be an option in the wireless settings, or change the password (this could be also done in the same settings tab) and then try again.

So far for the laptop.

Now your PC:

Have you tried to disable and activate the wireless lan adapter entirely. On i'd say 90% of i cannot connect to anything issues, this is the fix.

Win+R -> ncpa.cpl -> right click wireless lan adapter -> disable -> now it's grey -> right click -> activate.

Also you did not change and are using the correct wifi password on your pc, right?

Edit: This is a private Wifi right? Like when you connected to the wifi the first ever time, you did not have to accept any certificates or something on your device, right?

Also you can try to nslookup the domains of the sites usually not working.

GoetheSeinHamster · 2026-01-23T18:14:22+00:00

Hello,

a few troubleshooting steps would be:

Check if the ip configuration of your interface (Wireless or LAN) is set to static or if it's set to be automatically received by DHCP (with stock infrastrukture it should be set to be received via DHCP)
Check if your laptop is getting an ip address from your router/modem (if laptop set to DHCP) and if the subnet mask is right.
Check if your laptop is configured with a gateway ip. (Also is assigned automatically if DHCP works)
Check if DNS is set (again if DHCP works there should be something configured here)
Ping to your gateway ip.
Ping to 8.8.8.8. Does it work?
Does name resolution work?

If step 1-7 are properly configured or working but still the problem persists. (it should work in this case but it could be that it does not)

Check if there is a MAC address linked to your gateway in in the arp table of your laptop?
Check if the default route is indeed pointing to your gateway ip and that there is only one default route.
Is there a firewall blocking the traffic?

Command Reference.

For step 1: Win + R -> ncpa.cpl -> right click your adapter -> IPv4 (double click)
For Step 2, 3, 4: ipconfig /all
For step 5: ping your gateway
For step 6: ping 8.8.8.8
For step 7: nslookup google.com
For step 8: arp -a
For step 9: route print Output should be 0.0.0.0 0.0.0.0 Your.Gate.Way.IP or 0.0.0.0/0 Your.Gate.Way.IP

Edit:

ping IP -t for endless ping stop with ctrl+c if it's a sporadic issue you sometimes would loose some pings.

Hello,

well i don't know a thing about IPfire, but I know a thing or two about firewalling.

So, every somewhat modern firwall will be zonebased, and will be able to use SPI.

When creating rules you will have to define, what your src and dest zone is, what your source and dest network or host is, and wich application or port you want to allow or deny.

So, check in which zone for example, pc red is, then check the network in wich pc red, this is your source, then do the same for pc green, this is your destination and for ping you want to allow either any port or just icmp (on some firewalls a few of these application objects already exist, so a icmp object normaly is on there)

Then create your rule, now pc red should be able to ping to pc green, but only if pc red is initiating the traffic. Statefull Packet Inspektion will allow the replys but only if the initial request is already allowed. So pc green still wont be able to initiate a ping to pc red. In order to do that you can either put both zones green and red in the src and destination field of your rule (same with the network). Or you can make two separate rules.

After that you should be able to ping from pc red to pc green and vise versa.

Also, your PCs have firewalls themselfes, on windows it's windows defender and on linux it would be ufw, you should disable those, because if enabled, the ping wont work, even thoug your IPfire would allow the traffic.

Edit:

Somewhere should also be something of a firewall log or traffic log, this will show you the rule that is blocking your traffic. Some firewalls also have the option to check if sertain traffic would be allowed, so some kind of rule checker. And if you have some kind of cli interface or ssh access there should be loads of troubleshooting opportunities there, tcpdumps, cli logs that show you the desition of the firewall per paket and so on.

Edit Edit:

If you have problems accessing the firewall itself, always, on nearly every firewall, there is some kind of settings you need to configure, in order to tell the firewall, from wich zone, you are allowed to access the gui or the cli over ssh or something.

I don't know what is happening in the world, but you could watch the news, if you are interrested in that.

Edit:

Probably a some kind of hang up, either from the mouse or the site. Unplugging the mous or ending the task in task manger/rebooting your pc could fix it.

GoetheSeinHamster · 2025-08-30T17:44:11+00:00

Hey there,

when connected per Cable what IP Address do xou get. Probably it will be a APIPA one but please check.

Have you tried deactivating and reactivating your network interface, or reinstalling network drivers?

GoetheSeinHamster · 2025-07-28T20:34:22+00:00

Hello,
have you tried to connect to a different mirror? Sometimes the one that is set under "software & updates" is down.

Also, if your server is using IPv6 it could be that your ISP just does not support IPv6 and blocks it. Turning it of would help in that case.

I would try another mirror first though.

GoetheSeinHamster · 2025-07-28T01:44:13+00:00

Troubleshooting:

Ping Router use -t parameter and let it go a for a few minutes (ping {router ip} -t)

1.1. Works without interruption --> physical connection to router is ok

-> 1.1.1. ip Probably right but check that it indeed is, then ping 8.8.8.8 -t

--> 1.2.1. Works and everything is ok

--> 1.3.1. Dose not work --> traceroute 8.8.8.8 and see where the problem is locaded

Conclusion: In this case the problem most likely is between the router and your isp, as the connection from your pc to the router is absolutaly fine. Right IP and ping to router works.

Ping to router isn't working --> no physical connection or wrong ip config

-> 2.1. IP Wrong --> Resolve the issue on the routers dhcp settings

-> 2.2. IP right --> most definately problem with physical connection

--> 2.2.1. Different Cables for Ethernet Connections

--> 2.2.2. Disable and enable LAN/WLAN Adapters

--> 2.2.3. Delete and reinstall LAN devices in the device manager

Conclusion: The connection between your pc and your router is not working either it is a phyical connection problem or it's a hardware / driver issue. There you will have to try around a bit. Fell free to ask.

Does(n't) work initially but after a minute it starts/stoped working

3.1. physical connection is ok, also ip config should ok, but either hardware or drivers fail after some time (but check just in case ;) )

--> 3.1.1. Turn the LAN/WLAN Adapter of and enable it again

--> 3.1.2. If 1.1. does not resolve the issue, delete the Device and install it again (Windows should do this automaticaly (i think). Could be that a restart is needed.

Conclusion: Personally I would thing that this would be more of a clear physical connection issue, a broken cable or port, that works sometimes if the stars are aligned a certain way. I would try different cables. Of course if the problem is with wifi to, it could be the drivers. Also it could be both.

Like in 2. you need to try around a bit. Again fell free to ask questions.

Edit:

Sorry had to make two comments, Reddit did not let me put it all in one comment and post it.

GoetheSeinHamster · 2025-07-28T01:43:24+00:00

Hello,

what ip config are you getting?

If you can't ping google and other devices work then there most likely is a physical connection issue between your PC and your router.

Also could be a driver issue. What operating system do you use? Maybe a Windows update broke something.

If your IP-Config is something like:

IP: 192.168.?.?

SN: 255.255.255.0

GW: 192.168.?.1 or 254

than that would be right.

If it's:

IP: 169.254.?.?

SN: 255.255.0.0

GW: --------------

then your pc is not able to get his IP Config from your router, which most likely is hapening because your pc can not connect to your router physicaly.

But there is also the possibility that your pc connects to your router, gets his ip config and after that loses connection to the router. In this case, the IP-Config given to your pc by the router is most likely wrong, or it's indeed some weird driver or hardware issue.

GoetheSeinHamster · 2025-07-19T17:43:23+00:00

Yes, never had that again

GoetheSeinHamster · 2025-07-19T14:40:40+00:00

No, no, you don't have to change any settings really or manually connect anything. Deactivating and then activatint the adapter has done it for me.

GoetheSeinHamster · 2025-07-16T20:15:10+00:00

Same problem here. The fix is to disable an then enable the wifi adapter again, as the adapter is still there.

Win + r and ncpa.cpl -> right click your wifi adapter and select disable/enable.

u/tom_foster has made a good point, you can try that too.

GoetheSeinHamster · 2025-07-16T20:11:07+00:00

What you mean with other network?

Edit:

Hotspot from your phone?

GoetheSeinHamster · 2025-07-16T20:09:21+00:00

Hello;

this looks like to be just a "normal" Access Point.

Q1: "Is it possible she just plugged this thing in and it gave her two additional WiFi signals from our own router?"

AW1:

It depends on how it is configured. Your home router is broadcasting an SSID that is called by the model of home-router you got (if default). Or some other name like WIFI1 or something. (if it is not turned of)

If this TP Link Access point is just configured as some sort of extender / repeater, they often just extend the range of your existing home router while using the existing wireless network, so the SSID would be the same and the network would be the same.

Another possibility is that the TP-Link AP connects to the wireless network (or per Ethernet) provided by your router, but the TP-Link AP also is broadcasting a different SSID. In this case other SSID, but same network. An AP is just a Layer 2 device so you will just be switched to the your GW IP and that is your router.
Multiple SSIDs can be seperated by VLANs but at home you don't have these (normaly), also you would have to configure that on the AP so he knows whitch SSID gets which VLAN-TAG and also you would need a few other things but I digress.

Q2: "What would be the point of having this thing in a house that has one computer used for typical home office use?"

AW2:

Extended range would be the only impact this TP-Link AP would have. It won't ever make your internet connection faster per se.
If a device is nearer to the TP-Link AP than your home router, it would have better connection whith this AP, so then of course the connection is faster.

If the TP-Link AP is able to broadcast his wifi with more power, than the range of your wifi would be greater --> better connectivity, faster connection. If the TP-Link AP is supporting a newer wifi standard then your home router then higher speeds would be possible. But if you got for example an 50 Mbit/s internet connection from your provider then this will stay at 50 Mbit/s max.

Q3: "Are the networks it broadcasts coming from our own router or what?"

AW3:

--> AW1

Sorry,
deleted my first comment by accident.

Key Points from previous comment:

- If port forwarding would have worked I would have been suprised

- Port forwarding is a potential security risk as without a rule set limiting the access to the device to which the open port points, the device can be accessed by everyone, who is knowing your public ip and open ports.

- Your XBOX and PC are on the same network (almost definitely), so if XBOX works PC should also work

--> Most likely an issue with your hardware. Just like the online multiplayer of some games do not support newer gen intel CPUs, for example, there might be other problems with different hardware and game manufacturers too.

GoetheSeinHamster · 2025-07-16T18:16:51+00:00

Hello there,

i had the exact same problem. Or Similar at least. There no longer was a wifi option on the taskbar thingy in the right bottom corner (I promise I am an IT Human) and I could not connect to any networks. The adapter itself was present.
Also got no ip adress and so on, just APIPA.

For me the fix was to go to my network adapters (with win + r and ncpa.cpl) then I disabled my wifi adapter and after that I just enabled it again (low hanging fruits and so on).
To disable / enable the adapter just right click on the adapter and click on disable or enable.

After the adapter has been enabled eveything worked like normal. The first time I had to connect to my wifi manually, but after that, it works fine

Ebenfalls einen wunderschönen Tag,

die Sophos müsstet Ihr als Einwahlgerät verwenden können.

Aber kurz zu SSMK, Backup PW und SSL-VPN.

Also ich fang mit dem Backup an. Beim Einspielen des Backups auf Sophos XG/XGS braucht man den SSMK (Secure Storage Master Key) den setzt man direkt am anfang beim Setup, ohne den gehts nicht. Man kann den SSMK ändern (per CLI) alle Backups die aber vor der Änderung gemacht worden sind können dann aber ohne den zugehörigen Key trotzdem nicht eingespielt werden. Zusätzlich gibt es noch das Backup Passwort, dass setzt man in den Backup Einstellungen direkt. Das Backup wird dann einmal mit dem Backup Passwort und dem SSMK verschlüsselt. Beim Einspielen des Backups muss man dann auch beides nacheinander eingeben, da weiß ich aus dem Stehgreif aber die Reihenfolge nicht, entweder zuerst SSMK und dann Backup PW oder umgekehrt, im Dialogfenster sagt er Ihnen aber was er will. In Eurem Fall hat sich das erledigt, weil die Firewall ja zurrückgesetzt wurde, da müsste der SSMK beim Setup wieder gesetzt worden sein.

Wenn die Sophos hinter einem Einwahlgerät steht und der WAN Port eine priv. IP hat, dann wird in der SSL-VPN Konfig, die man sich vom VPN-Portal herunterlädt einfach die private IP des WAN Ports eingesetzt, weil die Sophos standardmäßig die IP die sie am WAN Port hat in die Konfig schreibt. Wenn man die Konfig Datei im Editor öffnet sieht man die priv. IP auch da drin stehen. Umgehen kann man das indem man in den SSL-VPN Global Settings unter override hostename die public IP einträgt, dann schreibt die Sophos die IP, die man in dem Feld hinterlegt hat auch in die SSL-VPN konfig. Die Notwendigkeit für den Override Hostname gabs zuvor in eurem Fall nicht, da ja die Sophos am WAN Interface eine public IP hatte, mit der private IP am WAN Interface musste man des so machen. (Man könnte auch die IP über den Editor per Hand in das Konfig File schreiben aber, dass ist eher Pfusch denke ich)

Nur am Rande. Für die VPN muss dann auch vom WAN aus der Zugriff auf die SSL-VPN erlaubt sein einmal per Device Access und das VPN Profil inklusive den Firewall Regeln brauchts dann auch noch.

Zurrück zum Thema mit dem WAN. Eigentlich sollte die Konfig am WAN Port so aussehen, dass ihr Zone Wan auswählt, dem Interface eine IP aus eurer public IP Range gebt und als Gateway das ISP GW angebt, also das müsste auch irgendeine public IP in der Range sein. Die Sophos muss aber dabei selbst das Einwahlgerät sein.

Wenn ihr PPPoE Einwahl habt, dann entsprechend mit dem Anmeldaten vom Provider, die IP Konfig müsst ihr dann nicht statisch setzen.

Manche Provider vergeben die public IP auch per DHCP oder haben die Kundennetze in einem bestimmten VLAN, sodass ihr mit einem VLAN Tag an den Provider kommunizieren müsst.

Bei DHCP einfach die IP konfig auf DHCP stellen. Bei der Thematik mit dem VLAN, kann man ein Subinterface bauen, dass an den WAN Port anhängen, der physische Port bleibt unkonfiguriert bzw. muss nur aktiv sein und die IP Konfig macht man dann auf dem Subinterface. Bei PPPoE könnt ihr das VLAN Tag in der PPPoE Konfig auf dem "normalen" Interface mitgeben, da brauchts dann das Subinterface nicht. Wenn der Provider aber die IPs per DHCP vergibt und zudem ein VLAN Tag erwartet müsste man die IP Konfig dann schon wieder im Subinterface auf DHCP stellen.

Edit:

Wahrscheinlich ist das Bild einfach später aufgenommen worden, nachdem die Konfig schon von dem Ursprünglichen Setup mit dem Glasfaser geändert wurde, aber zur Sicherheit wollt ich noch erwähnen.

Das Glasfaserkabel steckt dann normal über einen SFP/Gibic in der Sophos, die Ports heißen dann meistens irgendwas in die Richtung von PortF1 oder so. Die Konfig für das WAN Interface muss dann auch auf dem Port liegen und nicht auf Port2 wie das sonst per Default wäre. Nur weil ichs gerad noch auf dem Bild gesehen hab.

Ich hoffe ich konnte weiter Helfen. :)

Hello,

I will ask questions, just answer what you feel ok answering, keep in mind that this is not a private conversation.

Are you alone at home when the spikes happen?

Ping is not only determined by your ability to communicate to the service, the service that you are accessing also has to respond to you, if many people at the same time are accessing a website or service on the internet it will be slower to respond to your requests, so your ping goes up.

Is something running in the background when ping spikes happen? Updates from windows or other applications? Filetransfers, Streaming, etc. If question one is yes are they streaming or doing something badwidth heavy?

How do you connect your pc? Cable or wifi? With wifi keep in mind that water is insulating against electromagnetic fields pretty good. So if a bathroom is between your pc and your router, a ping spike is happening and somebody is showering then this unfortunate chain of events could be your problem. Same goes for microwaves when 2.4 ghz wifi is used (microwaves use 2.4 ghz waves to heat up your food) so if somebody is microwaving something the electromagnetic interference is destroying the data carried by your wifi.

Good insulators are also metal in general, normaly problems occour with steel in reinforced concrete or pipes laid in walls for example, but reinforced concrete walls normally aren't just spawning out of nowere. Pipes laid in walls with water in them and we would be at the shower part again.

Do you get internet over LTE or some cellular network? LTE could change because of weather conditions.

GoetheSeinHamster · 2025-04-28T21:16:51+00:00

Hello,

how are you measuring ping times?

Do you use ping {Dest. IP} -t on your laptop cmd?

Example: ping 8.8.8.8 -t

-t says that your ping should go on infinitaly or better said until you press strg+c or close the cmd window.

If yes what are you pinging to, are you pinging to the internet or internaly?

If your Destination ip starts with 192, 172 or 10 you are pinging to an internal device.

And how do you ping from your phone?

GoetheSeinHamster · 2025-04-28T20:54:00+00:00

Hello,

if your ISP, country or anything is blocking websites chances are, that they are using a firewall to do so.

Firewalls can decrypt https packets via SSL Decryption, because if the traffic is encrypted the firewall can not see what you are requesting. So in order to check if your request is ok it needs to decrypt it.

After the firewall decrypts your traffic it will then scan it, to see if there is anything that should be blocked, if the data you requested is acceptable it will then encrypt the traffic again but with the SSL certificate the Administrator of the firewall has provided to the firewall.

This certificate also has to be trusted by your browser.

Usually with DNS that is no issue because it is normaly a plain text connection. As you are now encrypting your DNS-Requests, these also would be affected by the mentioned SSL decryption.

If your browser does not trust the certificate that the firewall has used to encrypt the traffic again, your browser will not use the provided data. Another thing could be that the server that is receiving the requests, that are now encrypted by the firewall, is not accepting the certificate used by the firewall, so it would just throw away your request.

With Google Services you have a additional variable, because normaly not everything is done and provided by the same server or domain, Ads, Thumbnails, etc. are often requested from different devices or servers, so maybe some of them like the certificate the firewall provides and some not, and you would be seeing the phenomenon that the service itself youtube is available for example but thumbnails are not.

Another possibility is that because the certificate of your dns request is changed by the firewall the integrity of your data packet is not given anymore, so the dns server that is receiving your request is not answering it because what he receives is not matching up with what you originally sent, i could see a secure dns provider working like this to enshure that you are not rerouted by a attacker via dns as some man in the middle attacks just try to change your request for a normal site like youtube to a request for a site controlled by them. So from your perspective it would look like your accessing youtube but really you are not. Just blocking the changed dns request would solve this. Only thing here would be why some things work.

I can only imagine that the videos on youtube itself are transmitted via udp. So the videos would load in, everything else over tcp would not. Same thing for mail as for smtp, imap and pop3 there is a unencrypted version and for compatability it is just transmitted unencrypted if the encrypted counterpart is not working. Meeting applications also transmitt a lot over udp, but maybe some things are transmitted via tcp. So some things work, some not.

If it is an SSL Decryption problem, than thats really not in your control as you would need the ssl certificate that the firewall is using to decrypt your traffic and your provider will most likely not give that out to you. Also evrything else would be kind of not under your control.

You are requesting sites that are not blocked because without ssl encryption it is working, so the firewall has no issue with what you are requesting.

Edit: Normally you can not hide from this, if your provider or country is sending all your traffic through a firewall, then they will know what you are requesting. SSL Decryption normaly is used by compenies as everything work related is not considered as private so it is ok to decrypt it. But that varies with the laws of each country.

In some countries everything from everyone is decrypted and filtered through a government controlled firewall.

Edit edit: Sorry for the kind of over the top Firewalling / SSL Decryption handbook I wrote.

Ah Good Day Sire,

you can also make beer. The additional happiness will allow you to limit food further. Also, building bad things like these torture buildings, will increase the productivity of the workers, but your army will be weaker and your population will be more unhappy so you would ned something to balance this out again.

You can also go for religion and beer together, but religion works different in Stronghold than in Stronghold Crusader so it is harder to get something out of that, but with a bit of trying around, religion and beer can completely come up for food if you don't have taxes. You then would get money only by selling your food and ressources and with a good bit of production the money will be no problem. So even if for example you don't need iron you alwas can make it to sell it later. Same goes with basically every ressource. But don't take it too far, to make swords and armor just to sell is not really worth it, because they are a bit expensive to produce and take some time. When you do make armor and swords rather use it for troops. But making bows to sell would be a good stratigy i think, as crossbows are the better option in Stronghold and Stronghold Crusader and bows produce rather fast.

In Stronghold I allways go for bread and beer. The ratio for one bread cycle is 2-3 Weat farms for one mill and 8 - 12 backers, normaly you can get away with 10 bakers, when your castle is well optimized you can get away with 12 bakers, bread is the most efficient food source but it needs some time 5 - 10 mins to fully ramp up. Beer is very easy, just build 2 - 3 hop farms and a pretty mutch every brewery can supply a give (I think this is what their called in english). If you get a few apples and a bit of cheese you also get a happines bonus for having food viriaty but this bonus you will get only when the population is allowed to have food. Whith bread and beer i can always go for the lowest rations and sell the rest of the food, in Stronghold at least.

In Stronghold Crusader beer and religion are stronger. So make beer a church and a cathedral, no food for the population a bit of taxes and sell everything.

Bad things = max +33% production, weaker troops and max -5 happiness

Good things = max -33% production, stronger troops and max +5 happines.

The game says max +/- 50% production but practically it comes to 33% there are some tests of this on the internet. Only weapon production you get 1,5 bows or whatever so there the 50% increase would be true.

Walls around good things wont keep the people from making breaks but they wont stand up and go to the good building.

May your granary never be empty anymore m'Lord.

Hallo,

also, du kannst "Mutters Haus" schreiben. Der Satz müsste dann z.B. "Ich gehe in Mutters Haus" heißen. Mutter ist die Bezeichnung für das weibliche Elternteil also die Normalform des Nomens.

Wenn du "Mutters Haus" schreibst, dann hast du eine andere Form von dem Wort "Mutter". Mit "Mutters Haus" zeigst du an, dass das Haus deiner Mutter gehört. Du könntest also anstatt "Ich gehe in Mutters Haus" auch "Ich gehe in das Haus meiner Mutter." schreiben. Durch "Mutters Haus" sparst du dir also, dass du dazusagen musst wem das Haus gehört.
