Unidentified Network - Ethernet

[Omikor]

So.... a few weeks ago my network suddenly didn't work. It was written Unidentified Network - No Internet connection. I've tried everything but it didn't work, so I bought a network pci card in order to fix the problem, and it did. BUT a few weeks later my ssd died and I bought a new one. Reinstalled Windows, and guess what, both the MB port and the network card don't work.

Sometimes the MB port is working for a few hours and then disconnecting again.

*Windows troubleshooter says: "Ethernet" doesn't have a valid IP configuration.

WHAT TO DO???

Are there other devices on the network and do they work fine?

[Omikor]

Yeah. I have another device connected to the same router ( I have a few Ethernet ports around the house) and it works just fine.

[drwevil]

you haven't  got a device with a conflicting IP address have you?

That can sometimes do bizarre things... 

 

[Omikor]

I have no idea... But in addition, the light indicator on the pci card is green (good).

Listen, I've tried everything, I'm telling you, someone really hates me up there...
