Have found recently when I was having problems with my older rockfish gaming powerline. That the powerline units have changed a bit since. Have a new TP now and it works a lot faster then my older unit. Have been where your at with low MBs in a house that I could not get a signal to my living room TV because of the lath in the house, and have used a net gear powerline for years, with very little problems. Except that the highest I could get from my router was a 3. So don't think the powerline would hurt, it may help your system if cable is not available ,which I switched to now for WIFI. But still use the powerline. Hope that helps you .
