I've come up against this problem and it's driving me crazy. My girlfriend's parents have dial-up (they can't get anything else) and have several computers which they would like to connect with that are not near a phone line. I had given them 2 wireless cards knowing that it's fairly easy to share dial-up over an ad-hoc network but they would not reach far enough. Therefore I purchased a used Dlink 802.11b router. It was the really popular one which name escapes me at the moment. But on to the problem: I cannot get a dialup connection to share over the router. I've done everything manually, tried to run their wizard to the closest specifications of what I have. Is there a way to do this? Any insight is appreciated.
