Page 1 of Dropped Ethernet connection

I keep getting a dropped connection on the PC.
Taskbar icon says I'm connected but no site loads on the browser and I get the following if I run a diagnosis.

'Ethernet' doesn't have a valid IP configuration.

It then fixes itself.
I'm also getting the same thing on my phone via wifi. The connected icon is there but querying the connection it says its not working but reconnects if I prompt it.

Not entirely sure where or what to look at.
Any suggestions.

Snaps

Check all your internal telephone wiring and socket connections are OK from the primary socket outwards.

I had a spurtious loss connection to both telephone and internet/wifi, and openreach (BT) via my internet provider did a remote test and said it was an internal to the house fault and not the line, and asked for a £70 visitation fee before any work commenced checking it out, so decided stuff that, and sorted it myself.

Found out it was a bad telephone wall socket, which I have now replaced, but also changed a lot of the telephone wiring during this exercise, to get it working right.

Is this WiFi? Can you connect a PC straight to the modem/router?

Normally I would say go get PingPlotter Free, and have it running to something like www.microsoft.com and when this happens go look where the packets are being lost.

But it sounds like your wireless router is the root cause. It might be overheating an restarting, it's responsible for both your wifi connection and providing all devices on your local network with an IP address via DHCP.

A bad ethernet cable wouldn't drop wifi at the same time, and a bad internet connection would still leave your devices connected, just unable to route to the internet. So I think the unit itself is rebooting for some reason.
