    initial v1  
    33**eg:** 165 is an ht20 only channel, but cause ddwrt thinks its valid, using another ddwrt device will result in a connection, while all the other devices do not connect or use 80mhz worth cause it violates 802.11 spec. any violation of the spec & channel portions shown here http://twimgs.com/networkcomputing/news/2013/10/graphic-80211-acChannels-all.png will result in devices not connecting, not using full 80mhz bandwidth, or no radio broadcast. as the chart shows for example, vht80 128 is LL only, 52 is UU only. if u try to do UL, LU, or LL on 52, it bleeds over into the 36-48 spectrum space below it & breaks spec.

    5 ddwrt is not following channel spec so u are being tricked by using ddwrt <-> ddwrt to test whats valid. test with your mac, iphone, any other 802.11ac device, u will quickly see the invalid combos.
