Ethernet wall outlet: no internet access

[Erik0]

Hello,

I have several ethernet wall outlets in my apartment. I have purchased a homeplug (TP Link) to avoid any cables running into strange places which works fine. However, as of today I seem to no longer have internet access. I've looked around in other topics but I have been unable to dilute a working solution from them.

Windows Network Diagnostics state: "Local Area Connection doesn't have a valid IP configuration". When I look at my IPconfig I notice I have a generic IPV4 address:

I currently have an old wireless USB-stick lying around but the signal is very poor up here because the router is down. Does anyone know how to fix my cabled internet?

Thanks in advance for all input. If you have any questions I will try to answer them as soon as I can.

Your HomePlug (if this is what you are using on your Ethernet connection) has LEDs showing the connection status, check your documentation.
I would, however, try to see where these Ethernet cables go. If you own the place, look around the house to see where these cables congregate. If you're lucky, you will need just an Ethernet switch. If you are not, you will need someone to terminate these cables with RJ45 connectors.

I feel a bit clumsy, re-configuring the homeplugs fixed the connection. Even though I still have no idea what caused them to stop working. Thanks for the help.
