We are looking at providing internet service to subscribers via wireless 802.11. I am looking at using PPPOE and Radius for authentication. Is this still the best way to handle authentication for fixed wireless subscribers? If so what is the best way to handle the PPPOE and Radius authentication. I have heard a lot of ISP's are using Linux, but I would much rather have a hardware based solution if possible. Does anyone have any thoughts on this? We are somewhat low density probably looking at a few hundred subscribers max.
