I have this exact problem: a couple dozen 2.4 Ghz APs are visible to me. Actual throughput at a distance of 6 feet from a 2.4 Ghz router is 1 Mbps (tested with multiple APs). I switched to 5 Ghz and luckily no one else has! Unfortunately, this doesn't solve the problem for all devices -- for example, the Chromecast is 2.4 Ghz only. With the chromecast, I practically can't use the chromecast in a room other than the one that the AP is in. I was thrilled when the Amazon Fire TV Stick came out with 5 Ghz capability. This made it possible for me to stream Netflix, etc. to the tv in the other room.
