I just got an RT-N66U router and loaded tomato-K26USB-1.28.RT-N5x-MIPSR2-115-AIO-64K.trx on it. I noticed that on 2.4GHz channels 1 through 4 are not choices. Also, FWIW, on 5GHz, only channels 40, 48, 56, 64, 153, and 161 are choices. My main issue is with 2.4GHz though — as I would like to use channel 4 on 2.4GHz. Why the reduction in channel choices with Shibby???
