I have the same issue and it is currently not fixed at the moment, I've tried everything in the book, the adapter is connected to a socket is not near a power hungry appliance

I would like to ask, could you go to device manager and tell me the name of your network adapter that you use on your computer please?

I have a hunch it maybe an adapter issue.

yes , its Realtek RTL8111G

Ive brought another Ethernet card and the problem exists but less often. I tried the power save tool that disables power saving on the adapters. It shows error 'Set Failed'

I tried too different versions of that 'power save tool', none of them worked! crapola h/ware and firmware in one package.

Found a solution. Word of warning, I'm not responsible if anything bad happens you have been warned.
Disable IPV6. I do not know why and I'm currently investigating why that is the case. When i lose connection, i can ping to anything, including YouTube, my default gateway, google DNS etc. I had to unplug and plug back in power-line adapters for it to work. When i ran the network troubleshooter, it says that 'Your computer appears to be correctly configured, but the device or resource (DNS server) is not responding' i thought that it maybe that the computer is using IPV6 DNS server (which my ISP do not use) instead of IPV4 DNS server. I disabled IPV6 and the issue is gone. Used 4 hours no disconnects. Usually once every 15 minutes. Surely IPV4 takes priority over IPV6. Weird I know

Hopefully that should fix it.

thanks mate, I will do this, not that I need IPV6 now, also I am suspecting the router, HHG2500, (BS from vodafone)

please tell me whether this fixes the issue. Thanks

sadly this solution did not work for me, I had some disconnects , only by restarted the powerline solved the issue.

could you please do the following for me:

When the problem occurs DO NOT disconnect or unplug the power line adapters. Could you run cmd (command prompt) and try to ping your default gateway, or googles public DNS (8.8.8.8 or 8.8.4.4). do you get a reply or does it time out.
type in
ping 8.8.8.8
also ping your default gateway
ping 192.168.1.1 (or whatever your default gateways)
please reply with the image of the result.

I'm at university at the moment, I have done other things along with disabling IPV6, I've changed some of the network adapter settings as well. I will tell you what I've done once I'm at home.

I know what you mean mate, I was not born yesterday, I am involved with IT since early 80s
when I mention 'disconnections' I mean total disconnection, there is no (ping) reply from any ip even router's one.
strange is that since last week I only have this disconnection issue just a couple times/day , so maybe its the shit router from vodafone
as when the net is disconnected I can see both the PL's using the tpPLC utility, I am pretty sure that the cables too are fine, tested them using a cable tester
