In the USA all the ISPs disallow re-sale of service. As these forums are squeaky clean (read those forum policies) such a discussion can't be had here.
My neighbor will lets use his wireless for a 1 time fee. He has a Linksys WRT54G. The signal is pretty weak but this works good enough about 3/4th of the time. I was thinking about setting up a repeater in a part of the house closest to his house. It would be the best value to get a router supports 802.11n and that could also function as a repeater so that I could have my own router for whatever future use and also support the latest standard. I did find a third party firmware called DD-WRT that has a feature called universal wireless repeater that will do the trick. However, DD-WRT will work on many b/g routers but only a few n routers. So if I wanted to go with DD-WRT my choice of n routers is very limited. If feature I want is supported in the manufacturer's firmware then DD-WRT is mostly moot and I can just go after the best product?
What do you think is the best approach to this problem?
