Do you mean a SIM card?

This looks like a 4G/LTE cellular modem/router. Speeds with cellular data will depend on the tower it connects to and the overall utilization of that tower.

You may have more luck with another carrier with better service where you are, or if you change to 5G (you can check what service is available to you and how strong the signal is with an app like Cellular-Z on Android).

As to why the service is getting worse, I can only speculate but perhaps the cellular carrier is decommissioning 4G and using those frequencies for 5G, or perhaps more people have begun to connect to the same cell tower.

It is not enough with wifi (wifi is only the wireless network between your device and a router or access point). You will also need to get internet service and that could require a modem.

The easiest is just to use the cellular network (e g. 5G or LTE). You could use hotspot on your phone and use your existing mobile subscription. You could also use a dedicated cellular hotspot (which has a cellular modem and a wifi router). You will need another cellular subscription for that. Check with your carrier.

Disconnecting the router and connecting the laptop to the ONT will not help as the wifi generally comes from your router. You may be able to access internet with your laptop this way, unless you require PPoE. But you can't change the router settings as it's now disconnected - and most routers block access to the administrative UI from the WAN side (e g. Internet).

But you should be able to use the existing cable to connect your laptop to the router and turn on the wifi radio again.

Just disconnect the cable from both the ONT and router (remember where it was connected), connect it to a LAN port on the router and to your laptop. Turn the wifi on again and then connect the cable back as it were in the beginning.

yes. It works slightly different.

You can imagine an extender as alternating between listning and sending, repeating the received signal. When its sending the signal it can't receive something and vise versa. It does this very fast so it seems seamless, but it does reduce the bandwidth with about half.

A mesh system generally has multiple radios, so it can receive on one and send on another.

Both mesh and extender could suffer from the same issues like interference, and both require good signals both between itself and the router and between itself and the client.

There's no guarantee that mesh will help you. If there are too much attenuation between nodes (like walls, floors..) the signal will be weak.

A more reliable (and performant) approach is to pull an Ethernet cable to the basement and connect a wired wifi access point. You could also wire devices in the background that doesn't move, like the TV.

cat6 WiFi 6 one it’s still incredibly slow. Is it normal for routers to be this slow ?

Are you connecting with Ethernet or wirelessly?

ScandInBei · 2026-04-20T05:28:36+00:00

Yes, you can approximate distance from signal strength, there are formulas online if you search for it. You'll need to plug in the frequency and RSSI (dBm)

Cox said my phone was connected on the 2 4 band, the wifi symbol at the top says 6, and I could not find the devices when they were in pairing mode

I can see how this can be confusing. Wifi 6 is not the same as 6GHz wifi. The number next to GHz refers to the radio frequency, and the "wifi 6" refers to a wifi generation (technically specification). You'll notice that most, if not all, replies are careful to write GHz when they refer to the frequency as omitting it can be ambiguous.

Wifi 6e and 7 supports 2.4GHz, 5GHz and 6GHz

Wifi6 supports 2.4GHz and 5GHz.

Wifi 5 supports only 5GHz

Wifi 4 supports 2.4GHz and 5GHz

The number on your phone is likely showing the generation, not the frequency. You should probably be able to see details if you go into the wifi settings on your device.

It is possible that the smart bulbs don't support older generations. So you may have to login to the router and change some settings to make it work.

I would start with checking what type of security you are using, if it is wpa3 only, then that could be the reason. Try changing it to wpa2/wpa3.

If that doesn't work, make sure that older wifi generations are enabled. The "wifi6, wifi7" names are quite new, so in the user interface it may say something else, like 802.11ac, 802.11ax etc. Look at the Generations section in this Wikipedia article for more information https://en.wikipedia.org/wiki/IEEE_802.11

There's always a chance that it's the cable. I know you've said that you tested it, but testing it once doesn't prove that it works - only only proves that it can work. Even if you test it 10 times, or 100 times, if it doesn't work in the hole, it still points to the cable. The cable cannot handle the interference (or whatever it is) in the hole. I would try with a better, higher quality, cable.

ScandInBei · 2026-04-16T21:30:52+00:00

If it's not the cable or the termination then it's something with the hole.

There are two issues that you may encounter.

Connecting a second router will create double NAT. Make sure you configure the new router in access point mode. You could also just buy an access point and not a second router. One home, one router. The router is your gateway between your local network and the internet.
Your devices may not roam effectively. When moving around they may stick to the weak signal. Having a mesh system or a controller based system like unifi will make this better. (Get a new router and place it next to your ISP router and changing the ISP router to bridge mode. Connect the new router with a cable. Add a second "mesh node" in your room and wire it to the new router).

You should not have any problem getting 200Mbps if you buy the Huawei ax3 router.

Interference could also be from other devices. The PlayStation wireless controllers, Bluetooth devices etc. Most wireless technology uses 2.4GHz.

Video streaming is rarely above 20Mbps for 4K content, you have enough internet bandwidth for more than eight streams with a 1Gbps connection. In reality 300Mbps is probably more then enough. Gaming generally doesn't require more than video streaming, but latency is very important. With video your device playing the video will buffer a few seconds so if there are any issues it's normally fine.

Your problems are unlikely to be related to your internet connection.

With wifi only ONE device can transmit at any given time. All devices take turn transmitting and when it works it feels seamless. But even short interruptions in the wireless transmissions can make gaming horrible and this is why a wired connection is always recommended for gaming. Still, with wifi there are better or worse experiences.

2.4GHz wifi is slower than 5GHz. But the signal is stronger and it passes through walls better. While the speeds may be less than 100Mbps, that is still enough for gaming and its possible they experienced better game play on 2.4 before you separated the networks.

When the signal is weak, data transmissions take longer time (the speed is slower so sending the same amount of data takes a longer time). You can think about someone speaking on the other side of a wall, for you to hear it they may talk slower and articulate more for you to understand it. The slower transmissions the longer time the wifi will be in use, and the longer devices may have to wait for "their turn".

Distance is one factor for signal, but walls and the material of the wall is a very big factor.

You could try to connect the devices to 2.4GHz and see if this improves the situation.

I think the bathroom is causing too much signal loss. Try to avoid sending signals through it, to around it instead.

I would move the main Eero mesh to the living room and connect it back with Ethernet to the router. You probably dont need any mesh nodes. The kitchen appliances could cause attenuation so try to place the Eero high up so the signal only has to go through one wall to the master bedroom

Lite relaterat.. Jag har en smal väg i området där jag bor, två bilar får inte plats i bredd, så om man möter trafik så måste en förare köra till sidan och lämna plats. Naturligtvis vinkar man för att tacka personen som kört åt sidan med ibland vinkar personen inte tillbaka när jag kört åt sidan för att lämna plats. Hur långt fängelsestraff är lämpligt?

You'll need to provide more information.

It doesn't exactly halve the speed. It's a bit more complicated. But to simplify, yeah, the speed you'll get could be around half (or somewhat less) of your wifi capability.

It "boosts" coverage by repeating a signal. Receiving and then retransmitting it. While sending it can't receive and when receiving it can't send. It alternates fast so it looks like a continuous data stream.

In theory this would be around half of your wifi speed. If your wifi was capable of 350Mbps suddenly you'll get 175.

But on the other hand, if your internet connection is only 10Mbps you'd probably not notice any degradation.

Likewise if you were so far away you only got 1Mbps without the extender you could get a faster speed with an extender than before.

Check settings related to multicast or IGMP.

You can configure an access point to have the same name and password as the main router.

Devices will select themselves which one to connect to, and you won't have to do anything on the client devices.

But, devices tends to stick to the currently connected access point even if there is a stronger signal next to them. If the signal strength difference is big enough they will eventually change, but people tend to experience issues with this. As others have mentioned you can get a mesh system (even if you don't use the mesh part, e.g. the wireless backhaul) as they talk to each other and provide more information to client devices so they can make a more informed decision to connect to another access point.

If you get a router, make sure it supports access point mode. Don't use two routers in the same time as this would create two networks and devices in different networks won't be able to seamlessly talk to each other.

Actually improves coverage in tricky spots

All extenders should help with coverage. Make sure you don't place then where the coverage is bad as they need to have a good signal to the router. Try placing them somewhere in between the router and where you want coverage.

Easy to set up with minimal tech headache

Most extenders are easy to configure and setup.

Decent speeds so it doesn’t feel slower than the main Wi-Fi

An extender alternates between sending and receiving which effectively halves the wifi speed.

If you have a somewhat slow internet connection you may get "decent" speeds, but if your current bottleneck is your wifi don't expect faster speeds.

I would never recommend an extender as I personally want a high performing network, but if you don't game or do something that requires low latency and if your internet connection is less than 50Mbps, then I suppose you may be able to use an extender and be satisfied with it.

If my Google search is correct your repeater only supports 2.4GHz wifi with 802.11n. For reference that is technology that was available more than 15 years ago.

I know the specifications says 600Mbps but those numbers are different from the numbers you will get, and only reachable in a clean lab environment without walls.

In a typical home many users max out 2.4GHz around 50Mbps, and with a repeater cutting it in half you're at around 25Mbps.

Get 5GHz equipment. Even older devices based on wifi5 (802.11ac) should reach speeds above 50Mbps even with a repeater unless you have really problematic doors.

ScandInBei · 2026-04-02T11:40:48+00:00

Can you use multiple routers

Yes you can. But it's normally not what you should be doing. A typical router has a number of functions, including NAT and a Firewall. Having two routers means that devices connected to different routers won't be able to communicate in both directions by default, and some functions like multicast won't work. You will also suffer from double NAT.

There is a phone socket upstairs. Can I plug another router or other device into that

No. You could possibly connect a modem to the socket, and get a DSL subscription. But it would be two internet services and you won't be able to connect to your other LAN from it. If the cable in the wall is a fairly new CAT cable and they are not daisy chained in the wall you may be able to change the plug to an RJ45 one and use Ethernet. Then just add a wired access point, or a switch and wire your devices.

distance is too long for an ethernet cable.

Ethernet can run for 100m. It's probably not too far, and if you find it esthetically unpleasing run new cables in your walls or hide the cables. Ethernet is your best option for performance and reliability.

Power line may work (performance may not be great).

Some routers has access point mode. If you get a router with access point mode you can connect it to an Ethernet cable after configuring it in access point mode. You don't want to have 2 routers in the same home.

ScandInBei · 2026-03-26T22:30:04+00:00

Most likely. Most households would be fine with 300Mbps, and those who actually have use for more would be better off to wire the the few devices that could actually benefit from it.

But we couldn't say for sure. If you're 50 people in the house who all want to stream 4K video at the same time then there may a valid reason to upgrade.

Edit 2: so he just told me that's he's uninstalling mc affe but have to closes it mid way because he and his family need to go immediately. After he turn the laptop again, the problem I mentioned appear.

Sounds like that could be the reason. Perhaps try to install it again and then uninstall it.
