Yet another unidentified network

[Rebel836]

Ok so, this problem is not a new one, but my particular problem is I can't seem to fix it using anyone else's solutions. The latest post in this forum of someone having the same issue was almost the same thing that happened to me to the T but I didn't use multiple different adapters or anything.

 

Short version is, I finally got a new pc, plugged in a cheap usb wifi adapter to install drivers while I waited for my cat 6 cable to get here, it finally does, I plug it in and I get unidentified network, no internet access. So I have been spending all day looking up solutions and I've tried everything I can think of.

 

I reset the modem and router many times

Reset the adapter

Updated drivers

Uninstalled and reinstalled drivers

Uninstalled my virus protection software

Used ipconfig /release, /renew, dns flush, winsock reset etc

I tried manually inputting static IPs

Disabled tcp/ipv6

Pretty much everything else I could find

 

When I first tried to use the /renew command I got a lot of notifications saying media was disconnected and that an error occurred while renewing interface ethernet : unable to contact your DHCP server. Request has timed out. I reset my modem after this and then my unidentified network changed to network but there was still no internet connection. At this point the wifi on the router just stopped working completely. I tried plugging my cable into the router to see if this might fix that issue but to no avail. I'm just about out of options here and I don't know if I should just give up and settle for wifi?

 

Also when I used ipconfig /all these are the results in case they help anyone diagnose my problem. It seems like it's trying to push IPv6 DNS servers at me but even trying to set my IP manually in the network adapter I can't seem to get anything to work

 

 

Edit: Also any time I try troubleshooting my network adapter it says "Ethernet does not have a valid IP configuration."

I would try two things:

1. Try a different Ethernet cable if you haven't already.
2. Try booting a different OS like Ubuntu

If both of these result in no internet and other computers get Internet off the same Ethernet cable it's sounding like you may very well have received a motherboard with a defective onboard NIC.

The fact you're getting a 169.254.*.* address, tells us that your network stack in Windows is working and that your adapter is sensing the port is up.

But for some reason your network adapter isn't negotiating with your routers DHCP properly. 

 

This could be configuration of the NIC, you haven't been touching any Advanced settings on the adapter Properties in Device Manager?

 

When you tried to manually assign an IP, did you enter the subnet mask and gateway as well? Something like this

I believe so yes. I can go try again just to verify but I tried both with the DNS input manually and automatically. For the IP address, should I be putting the 169.254.174.108? Then 255.255.255.0 and 192.168.1.1?

 

So 169.254.174.108

255.255.255.0

192.168.1.1

 

8.8.8.8

8.8.4.4

I tried it again and this was the prompt I received and to no surprise, it did not work. What is my gateway supposed to be exactly? The one in ipconfig is an ipv6 address so I can't use that. I always thought it was the address used to access the router admin settings

No your IP address has to be in the same subnet. Make it 192.168.1.x (e.g 192.168.1.15)

And make sure your Subnet mask is 255.255.255.0

This is what happens next

You're getting that warning, because you're connected to WiFi (so you'll have 2 network interfaces on the same gateway)

Just click Yes, and try turning off the WiFi and see what happens.

Didn't help. I also read somewhere that there might be issues with the modem being in "modem only" mode rather than full router/consumer gateway? I don't know if that's related or not but I'm running out of options

Some more info.....

 

What was the experience when you changed it? Still not able to load a website?

Can you provide another screenshot of ipconfig /all

Can you also try to ping 192.168.1.1

[Jarsky]

Also what modem are you using? 

Your computers new ethernet cable is definately plugged into a LAN port and not a RJ45 WAN port? Photo of connection to modem/router?

[Rebel836]

It still said unidentified network - no internet

The photo is of the back of the modem where it's plugged in, the wireless router is a netgear R6020

Hold up, so you have a Technicolor cable modem router, and a Netgear wireless router...

So I said 192.168.1.1 as that's the gateway for your Wireless router.....can you plug your computers ethernet into your Netgear...it should just work then. 

[Rebel836]

I can give it a shot, though I think I tried that and it said Network instead of unidentified network, but it still had no internet connection and also the wifi stopped working

Is it displaying as a public network profile or private?  sounds like it's public to me and then not letting you connect to the internet.

 

If it's public, right click windows start icon, and select [settings] from the menu, then click [network and internet], or right click network icon in the taskbar and select [open network and internet settings].

Select [Ethernet] from the sidebar, then click the [Network] icon in the main page.

Clcik the [Private] radio button. That should be it. You can also edit your Ip address and DNS settings here if you require.
