A long time ago I followed John Gray's advice and purchased some Solwise Homeplug 'data over electric mains homeplugs'. They have been a lifeline for me because for some reason (brick walls, distance?) the wifi connection from my desktop PC was a) slow b) unreliable. The homeplugs have worked superbly for me'; I agree with John that, occasionally (not very frequently), I have to power cycle a plug. I bought the ones that have a mains adapter in them so I don't lose a power point where they are plugged in.
I would thoroughly recommend them. I have no connection with Solwise in any capacity.
Hope this helps

PS : Talktalk sent me a NOW TV box for free, and because it was the free one, it isn't wifi. I don't use it, but the other day I was browsing through its manual and noticed that it had to be connected to the router by an ethernet cable i.e. the manual claims homeplugs won't work/be suitable for streaming. Check your streaming device manual before purchasing homeplugs.
