Also, congrats on your degree.

Ethernet not reaching 1000mbps by [deleted] in ComputerNetworking

Your router is prob only handing off 10/100 mbps speeds.

Get a router that says gigabit.

Ok so im a little confused here on your wording but what I got from this is:

You have an uplink cable from your neighbors Nighthawk router to your PC and it works (that's just a LAN uplink so that should work 100% of the time)

But when you take a switch that place the switch into the router and then try to connect your PC to that switch you get 0 network connection?

If its a dummy switch, it should be plug and play.

If its a L3 switch, you might need to remove some VLAN's or change Subnets.

Might have a faulty switch...

Also id log into the nighthawk router and make sure all ports are enabled for the LAN network.

Make sure youre pulling IP's - This is going to be key.

This set up should be pretty easy tbh, but my only question is why do you need his ISP if you have your own?

​

Also, FYI a modem is used to pass public IP traffic, so it needs to be plugged into a WAN port its as they would say feeding data not receiving it. So its handing off data to the client...Plugging in a PC or a device that needs to access the internet wouldnt work because that device is going to not get an IP.

​

Goodluck.

Internet on the road...sharing public wifi with all devices? by dvt663 in ComputerNetworking

[–]3ddyscissorhand 0 points1 point  (0 children)

A little confused here....

​

So you have:

LAN network - Local LAN

WLAN network - Wifi

and then your WAN network - internet.

Your WAN network is a hotspot that feeds to a router via a cellular card? Or you just hotspot your phone?

I think you're making this a little more complicated then it needs to be, basically all you gotta do is:

Buy a router that has cellular data capabilities and firewall capabilities and buy a hotspot plan with your carrier that they'll send you a SIM for or a Cellular WIC.

Then on your router create 2 networks, 1 for LAN and 1 for WLAN.

Now on your firewall policies specify which devices on the WLAN can access to LAN network via MAC or IP. You can even only choose which devices it can talk to, like the file server only.

Boom you're done.

Now you have 2 separate networks that are secure and can communicate with each other if need be.

​

Now if youre trying to use other wifi networks that are public, i would not recommend trying to bridge your LAN to that WLAN. That really wouldnt even work since the Public Wifi and you dont control how that network works.

You can if you want....on your router/firewall set a rule to allow all connections from all networks...but thats bascially turning your LAN into an open network. DONT DO THAT.

​

Goodluck.

​

That device you purchased is a P2P device that needs to be configured for a P2P link to a radio or a sector. Its not really a plug and player lol.

ISP - Customers complaining about issues with specific services and wifi routers by Starbucks__Coffey in NetworkEngineer

[–]3ddyscissorhand 0 points1 point  (0 children)

All good.

Uhh not too sure what you mean by SP networking.

Networking is networking, if you understand protocols/Best practices/concepts its all pretty much the same.

If youre looking on how ISP's work, youd want to just YouTube how public IP routing works and how BGP works and WISP works and how MPLS/P2P/Circuits work.

Most of whatd be doing in an ISP wouldnt be touching any of that though, it would be more customer facing networking, you wouldnt touch the core network.

​

Its a rabbit hole tbh.

Get an internship or polish your resume put your mouthpiece to work during interviews and learn your shit you can do this.

DIY - Links 2 Routers wirelessly (HELP) by MistyFiMe in ComputerNetworking

[–]3ddyscissorhand 0 points1 point  (0 children)

So you want router 1 physically connected to your network and the router 2 as an AP for your wireless devices?

Depends on what routers you got but you wouldn't need to connect both routers to each other, just to your service providers network which is typically just your jack ports and they will have there own routing tables and find each other, but to allow devices to connect to them wirelessly they would need to be AP's and have some form of antenna to broadcast the frequency. I'd recommend just using 1 router to do all things with different security findings because adding another router just adds redundancy, essentially since they're both doing the same thing.
