As I mentioned before, Yes, there are tons of them (literally 13, all single family structures, this isn't an apartment), but knowing that doesn't help.

What do I do with that information?  The only unused channel is 5, but the DIR-655 isn't selecting that channel, it's using 2+6.  There are 4 networks on channel 11, 2 on channel 1, 1 on 2+6, 2 on 6 only, and 1 on 6 only, and 1 on 4 only.  None of them have amplitudes near mine (mine is -30, the nearest is at -50).  Most of them are running WEP, two others are running 300(N).  Should I just select the least used?  Shouldn't auto channel select pick the optimal channel?

Having many routers near by, the router should try to select an open channel and maybe it's having a problem thus its getting stuck. Manually set up a channel thats open, 5 then try 7-10? test each one out and see what you get.

Auto channel can cause signal lost because the router has been trying to avoid the other router channels.  There are "three" main channels, 1, 6, and 11.  The other channels are the side band channels of these three channel.  Usually use manual selection channels 1, 6, or 11 should prevent signal drop.  Most people use channel 11.  Most home phone devices use channel 6.  Therefore, you should use channel 1.  Just place the computers at the line of sight direction of the front router so that the router signal cannot be cancelled out by the nearby routers, and the computers can receive the max strength signals from the router.

The poor wireless down could be the FIREWALL setting (use endpoint independent), enable QoS settings, and enable UPnP and Multicast Streams. I set the uplink speed at 55,000 instead of auto detect, Beacon with 33, RTS/Frag threshold at 5,000 to boost up the performance of the router.

I have tried on my dir-655 A4 router with firmwares 1.21NA, 1.32NA, 1.33NA, 1.34NA, 1.35NA, 1.21EU, 1.31EU, 1.34EU, 1.31RU, and 1.34WW.  Firmwares 1.33NA, 1.31EU, 1.34EU, 1.31RU, and 1.34WW are the most stable upload/download firmwares.  Personally I ended up with 1.31RU (English) firmware for its speed and stable performance.
