For a month now I've been operating a free WISP in the Berkeley Marina (80211b <-> full T1). Yesterday I noticed that a new commercial operation (darkersun?) has put up at least one access point on the same channel as one of my free and open access points. And it's causing a lot of interference. Suddenly I'm getting 30% of my received frames having errors, lots of duplicate frames, and generally very poor performance (though my signal is still strong).
I suppose the "solution" is to tell anyone who wants to use my network that they will have to get a directional antenna and aim it at my access point, but I'd been working for some time to come up with a system that provided good coverage over most of the marina (got 2 12db gain sectors and dual radio access point on the roof other Berkeley Yacht Club.)
I'm curious how others have dealt with the issues of crowded 802.11b spectrum, overlapping channels, conflicts between commercial and free networks. Hopefully I can find out some way to keep my dream of free, community supported wireless Internet service alive. At the moment I'm getting awfully frustrated.
