In case anyone's interested in "networking" without a smidgen of hassle, I recommend NetGear Powerline Adapters **, as an alternative to airport and some of its reported vagaries,
or stretching more ethernet cables..
Imagine, getting a network as easily as when you first plugged in a your Mac . . . anywhere in your domicile!
If you have a router, - - and a dwelling illuminated by something other than candles or oll lamps - - merely 2 NetGear adapters is all it takes to move any computer you might have "established" somewhere else to wherever you might enjoy surfing, as yers truly is doing at this moment.
Highly recommended.
** Got 'em for a good price from Amazon, today . . .
