Powerline/EOP wifi , long term reliability ?

Hi there

I was wondering how everyone was finding the long term reliability of the consumer EOP/powerline pairs ?Ive installed a few, Netcomm/TP Link , and have had some issues with devices resetting/losing pairing etc .

Also, how about reliability of the actual signal/connection through the mains. Had any issues with that dropping off ?

I know these devices are consumer level,best effort,last resort option, but many homes just dont have the option to run new network cabling throughthe walls & floors . Home users expect wifi to just work, perfectly, allways
