Did you just change the motherboard and not do a clean install?
Usually changing motherboard while keeping an old install of Windows can cause a lot of driver conflicts due to older drivers from the older motherboard.
Have you tried installing the latest network drivers and see if that helps?
yeah i did a clean install as i moved my OS onto an SSD at the same time.
You're getting massive latency with that pingtest. I would expect ~15-40ms to bbc on a fibre connection, you're getting 585ms.
Try a tracert google.co.uk which will show you the different hops to the server including the first to your router. It should be ~3ms using homeplugs. I'd hazard a guess thats where your problem is..
Can you try connecting a longer patch cable straight to your router?
before upgrading i was having no problems with the homeplugs which is strange, i have tried a patch cable straigh to my router and no different
