[Help] Internet Keeps dropping - any way to monitor/debug?

My PC is connected to the internet via ethernet over the mains with one of those homeplug adapters. 

When the internet is working, it works fine - zero issues. However it seems to cut out - randomly - for anywhere between 1-5 minutes.

• A similar (if not same) problem happened at my old house.
• No other devices in the house drop.
• Normal debugging reveals no problems.

Any ideas? 

Is there any sort of program I could run in the background, so that when my internet drops... I can narrow down the cause? 

I am pretty lost here, 

Thanks, 

Sam

Try pingplotter. Set one test to the IP of your router, one to the IP of the router side powerline adpater, and one to a internet IP(ie 8.8.8.8). 

Also, is your computer the only one using a powerline adapter?
