I have a wireless router plugged into a dsl modem. Our download rates are 160kps at best. I called router company (Belkin) and they said to set the router up as an access point. Basically plug modem into one of the ports (not dsl port) and change some settings. 1. Why would they have me do that? 2. Why would that increase tranfer rates? 3. Anyone think this is wise procedure? 4. Will I still have all the router security stuff with this set up?
