We’re running a Belkin Wireless G router in my office. I had to rummage in my garage for a few old wireless USB dongles, but it’s much nicer than having to string CAT-5 all over the place. (I hate cables.) Some of us were suffering deadly latency and frequently-dropped connections, which was annoying as hell. I flashed the firmware and tweaked every setting on the thing, but the problem persisted.
Then I had lunch with a friend this week and he suggested that I switch the router from Channel 11, which I had thought was the best, to Channel 6, which is actually the strongest. Blam-o! Now we all have a much stronger signal and no drops. Brilliant.
