What I would like, is to be a good neighbour and lead by example and control the scope and falloff of my own wifi.
Doing a survey at the boundaries, I can see some places that the signal has unnecessary reach.
I've tried the standard things like changing the position of the routers, the antennas and the size of the antennas, but most of this has resulted in incremental drops.
Sheilding the antennas from certain directions and focusing towards where I need signal, would be idea. Most of the tinfoil solutions I've seen, increase the focus forwards. That doesn't actually solve the problem, as I don't want to deaden one direction and amplify another.
Am I also shooting myself in the foot by giving my neighbours and their 'Auto' channel-choosing routers the opportunity to take domination of the channels I currently enjoy?
Looking for some ideas and comments.
