Ive been sceptic for quite some time to home plugs sice it's early days. But I gave it a go in our new house due to our position of the living room compared to the computer room where the PfSense box are.
So I tried a home plug solution for the HTPC and I must say I have not had a single problem and the speed is resonable, I have a 1000/1000Mb/s fiber connection and the htpc do not need more then 50-100Mb/s and that the home plugs I use deliver without problems.
I don't use wireless since it works so much better with cables but now I will use home plugs for less critical machines which saves a lot of cable management 
So I will recommend haywire to try home plugs, they have matured a lot.
I been using them for years and years. The newer generations are really small now and you even get ones that have power pass through and wifi though they little more expensive. What I have done in my last few houses, power plug from hub connected to fiber, to power plug upstairs connected to old router. Swithc DHCP off on router and make sure its in same IP range as other router. Hey presto wirless throughout house and four ports for wired connection in man den
