"ethernet doesn't have a valid ip configuration"

Question

"ethernet doesn't have a valid ip configuration"

Hi

I use an apple time capsule as a wifi router. It is wired to two other airport express routers to extend the range.

Everything has been working fine for months, but I shut down my PC (Windows 8.1) on Friday and started it up on Monday. On Friday I could connect to the internet in the normal way. On Monday it's not working.

I have told Windows to forget the network, then I connected to it again with the correct password. I get an error message "Ethernet doesn't have a valid IP configuration". I have also tried connecting using an ethernet cable but get the same result. I have checked my IPV4 and IPV6 settings to make sure that the IP address is obtained automatically, which they were and are.

There are many other devices currently connected to the wireless network and they are working fine (another windows PC, ipad, iphone). It is just this one PC that cannot connect.

To be clear, the PC was not turned on between Friday and Monday. This issue has just happened. It's possible that another device joined the network over the weekend so could the time capsule be "full" somehow?

I have tried turning the time capsule off and on, and also the internet router. And reset my PC's network adapter, and restarted twice already. Without any luck.

Would appreciate some help!

OK, have just "solved" this somehow. Having forgotten the network I was then entering the wrong wifi password. When I put the correct one in, I can connect to the network and use the internet.

The weird thing is that I never got an error message before telling me it was the wrong password. It appeared to be connecting. Also the ethernet connection should have worked surely, as that doesn't need any code.
