Ethernet 2 doesn't have a valid IP configuration

Josh B · 17 Apr 2020 at 00:21

Hi guys, first time on the forum and still a newbie to having a pc (last one i had was vista many years ago!)

I'm really looking for some help. I bought a Medion Erazer Gaming Notebook X17803 about just over a month ago and everything has been working perfectly fine up until tonight.

When it tries to connect to the internet through ethernet cable it comes up with the error in the post title. (It connects to WiFi just fine.)

I first tried restarting the modem which worked for about an hour and then the issue came back.

I followed some online solutions, such as updating my drivers for the network card and doing ipconfig renew and release on the command prompts and also doing a dnsflush too and restarting the laptop each time. None of these have fixed the issue. I also attempted to put in the IP address manually but didn't know what to put in where so i unfortunately gave up on that endeavour.

I will admit to being wary about diving too deep into the system settings and such because I haven't owned a pc in years, but I'm wondering what else I can try to get this fixed or if I need to send it in for repairs?

Thanks in advance!

A longshot, but are you using Powerline adapters? If you are, did you set your own encryption keys or just plug them in and use them?

actually I am using a Powerline. And I don’t know anything about encryption keys (still kinda dense with it all, sorry!) I just plugged in and went.

it’s a Powerline from my uncle who’s an electrician.

It looks something like those, it is a TP link one. I don’t know the model name or anything. My uncle just had it spare from his van. (He’s an electrician and it’s ones they give customers so that they can connect it into their house to download an app for their water supply tanks)

Find the model and download the instructions. They'll tell you how to set your own encryption keys. You can usually do it using a button on the adapter or with a software utility.

All the adapters use the same keys out of the box. This means you can also have a neighbour using adapters with the same keys which can result in your network linking to theirs. This, in turn, can result in the kind of problems you're having.

No guarantees, but worth a shot.

It's unlikely to be a hardware problem with the computer. Ethernet ports tend to work or break completely.
