Benjimoron:
Apologies, I now understand what this piece of kit does!
I would still use a wifi router on its own to extend or sort out the current router.
yeah thats my way of thinking to, but some people like to throw money at a problem first, all depends if u have more spare time or cash i suppose.
tbh in some instances he has gone for the right product.
given good electric cabling this will give him both powerline and wifi any where he wants it
very unlikely to be unable to work over one or the other so a pretty good spend money and fixit solution
