That's what got me thinking about this in the first place. Sure is a good way though to make them think twice about asking again:eg:
The guy across the hall told me he would give me $20 or $25 a month for my Wifi access. Not much considering I pay just about $200 a month for my Comcast package.
It would be nothing but hassles, as the signal isn't even that strong, the first one I gave to lives down the hall, halfway the length of the whole floor and he has trouble getting a good connect..
Steve001's link told me exactly what it's about, it's there for friends or family who have Comcast and a curtisy to them. Those who don't have Comcast, I can only give access to 5 and then there are still other rules..
