Invalid ethernet Configuration

[rotund comet]

Hey, since yesterday im having connection issues. Im connected via ethernet (the wifi is working) but on the network pannel it says "unidentified network - no internet". I tried troubleshooting but all it did was disable the ethernet network adapter. Does anybody know how to fix this? Tried rebooting aswell

When troubleshooting after enabling the ethernet network adapter it said i didnt have a valid IP configuration

Go to search > type in ncpa.cpl and hit enter > Select ethernet adapter then right click and properties > Select Internet protocol version 4 then hit properties > send a screenshot

Im using discord on my phone since i got no internet, are photos fine aswell? Also my pc language is german

[lime monolith]

Yes Phone photos are fine too.

[lime monolith]

Okay. now can you do the same for the wifi adapter and send a screenshot of that too?

[rotund comet]

I dont have a wifi adapter

Sorry, when saying that the wifi works i meant on my phone

[lime monolith]

Oh okay. On the bottom one. tick "Folgende DNS-Server" then type in "1.1.1.1" and in the bottom one type "1.0.0.1" then do a restart and take a look if internet is restored.

[lime monolith]

should look like this.

[rotund comet]

I guess i should reenable ethernet network?

[lime monolith]

yes

[rotund comet]

Thats odd, does it take time to activate? Because it stays on "deactivated"

[lime monolith]

it should activate instantly. Did you right click on it and select enable?

[rotund comet]

Yes

It also said in the popup that it activated

[lime monolith]

can you try restarting and checking if its still disabled?

[rotund comet]

Sure, ty

Oh now that u mention it, the pc doesnt really restart, its stuck in this screen

Was the same yesterday, had to do a cold start

[lime monolith]

is there a windows update pending in the background?

[rotund comet]

Not afaik, ill check

The dns settings are updated and the adapter enabled but it still doesnt work

[lime monolith]

So did it currently restart or did you have to do a cold start?

[rotund comet]

Cold start

[lime monolith]

okay can you go back to ncpa.cpl panel then select ethernet and right click and click on Status then send a photo

then click on details and send another picture.

[lime monolith]

.

[rotund comet]

Shouldnt this be a private ip address? Like 192.168...

[lime monolith]

are you able to access your router config settings through your phone? usually in settings and then LAN there would be the settings that should be assigned to the computer. We can manually assign them for now so you can run windows update and a couple commands to repair your pc not restarting and not detecting the ips correctly

[lime monolith]

You dont have to change anything in your router. just be able to see the IP's

[lime monolith]

If not what you can try is to right click the ethernet adapter > properties > then untick Internet protocol 6 and Client for microsoft Networks then click ok then try disabling and reenabling the adapter.

[rotund comet]

I have a router but i cant find its ip for the web configuration, i have a wlan repeater to which im connected via ethernet, which has a web config but the address isnt reachable from pc and on the phone i get a timeout

[lime monolith]

Can you try doing disabling the above? if that dosent work then you'll probably have to connect directly to the router once so you can write down the configuration. altho we could still try one thing but as you said restarting dosent work it may get you stuck.

[rotund comet]

Ill try that

Looks like it doesnt want me to do that xD

[lime monolith]

still stuck?

[rotund comet]

Yep

[lime monolith]

Alright. try to close it down then open command prompt as administrator and run the following command "sfc /scannow" without quotes.

after that command is done run the following ones in order aswell. Without quotes

"ipconfig /flushdns"
"ipconfig /registerdns"
"ipconfig /release"
"ipconfig /renew"

[rotund comet]

Im running it, also i was looking for the manual of the router but i couldnt find an ip for web config anywhere

[lime monolith]

alright. after all those commands are done running type this command in "shutdown /s /f /t 0" and run it. It should do a complete cold shutdown. Hopefully close enough to a restart.

[rotund comet]

Is renew supposed to take long?

[lime monolith]

Not really. leave it for about 2 minutes

[rotund comet]

Should i still run it?

[lime monolith]

Seems like the router or extender does not respond to the request of the computer to give it its Ip config.

[lime monolith]

You can still run it yes. altho it seems like the issue is the extender. Do you have another laptop or computer you can try to use and go into the extender's web config?

[rotund comet]

I think so, wait

Tried to connected via ethernet on my laptop, dont have internet either

And i cant connect to the web config

[lime monolith]

can you try to connect with the laptop to the main router and see if you get ethernet internet there?

[rotund comet]

Yes it works

[lime monolith]

can you open a command prompt on the laptop as administrator then type in "ipconfig /all" without quotes. then under the ethernet adapter write down the Ipv4 address, Subnet mask address and DHCP server.

[rotund comet]

Oh i found the web config for the router

[lime monolith]

can you find out the configuartions for the wifi extender?

[rotund comet]

Dont think so, it cant connect to it

[lime monolith]

Or if your router supports it we can also try adding your computer to Static DHCP

[rotund comet]

Should i still do that?

[lime monolith]

yes you can do that.

[rotund comet]

Oh i cant connect to the router with ethernet, its in the attic

Im connected via wifi

[lime monolith]

Ah. So you have access to the router. In the main page Under LAN can you see your Computer connected to the router?

[lime monolith]

Should be something like "DESKTOP-XXXXXX"

[rotund comet]

No but im connected to the extender with my pc (ethernet), not the router

[lime monolith]

Can you try resetting the Extender?

[rotund comet]

Yes

[lime monolith]

make sure to reset it by holding down its reset button with something thin.

[rotund comet]

It seems to work now, thanks alot

[lime monolith]

no worries. have a good day.
