Network Adapter problem?

[Trevor Appleton]

I used to very rarely see my internet connection dropping, then a week ago it started dropping 3 or 4 times a day. This evening it stopped altogether.

When this occurred I could it working again by a combination of switching the router on and off rebooting the computer and running the troubleshooter for internet connection Eventually it came up with a message 'repair as administrator or similar and that worked.This option now no longer comes up.

Other computers connected to the router are fine.

I use homeplug adapters for the affected computer and have tried replacing them at both ends. Device manager says the network adapter is working fine. I have run the troubleshooter it says the pc doesn't have a valid ip address.

Is the power plan allowing the adapter, pcie or usb bus to be put to sleep or conserve power in any way?

It puts the PC to sleep after 10 mins but I cant connect at all.

Have switched power option to recommended and both sleep options to never but still have the problem.
