I've made the (very simple) changes myself and the kernel appears to be sane though I haven't yet attempted a connection at 10 or 5 Mhz, 20Mhz definitely still works .. $ ifconfig -v ath0 list channels Channel 1 : 2412 Mhz 11b Channel 6 : 2437 Mhz 11g/10Mhz Channel 1 : 2412 Mhz 11g Channel 6 : 2437 Mhz 11g/5Mhz Channel 1 : 2412 Mhz 11g/10Mhz Channel 7 : 2442 Mhz 11b Channel 1 : 2412 Mhz 11g/5Mhz Channel 7 : 2442 Mhz 11g Channel 2 : 2417 Mhz 11b Channel 7 : 2442 Mhz 11g/10Mhz Channel 2 : 2417 Mhz 11g Channel 7 : 2442 Mhz 11g/5Mhz Channel 2 : 2417 Mhz 11g/10Mhz Channel 8 : 2447 Mhz 11b Channel 2 : 2417 Mhz 11g/5Mhz Channel 8 : 2447 Mhz 11g Channel 3 : 2422 Mhz 11b Channel 8 : 2447 Mhz 11g/10Mhz Channel 3 : 2422 Mhz 11g Channel 8 : 2447 Mhz 11g/5Mhz Channel 3 : 2422 Mhz 11g/10Mhz Channel 9 : 2452 Mhz 11b Channel 3 : 2422 Mhz 11g/5Mhz Channel 9 : 2452 Mhz 11g Channel 4 : 2427 Mhz 11b Channel 9 : 2452 Mhz 11g/10Mhz Channel 4 : 2427 Mhz 11g Channel 9 : 2452 Mhz 11g/5Mhz Channel 4 : 2427 Mhz 11g/10Mhz Channel 10 : 2457 Mhz 11b Channel 4 : 2427 Mhz 11g/5Mhz Channel 10 : 2457 Mhz 11g Channel 5 : 2432 Mhz 11b Channel 10 : 2457 Mhz 11g/10Mhz Channel 5 : 2432 Mhz 11g Channel 10 : 2457 Mhz 11g/5Mhz Channel 5 : 2432 Mhz 11g/10Mhz Channel 11 : 2462 Mhz 11b Channel 5 : 2432 Mhz 11g/5Mhz Channel 11 : 2462 Mhz 11g Channel 6 : 2437 Mhz 11b Channel 11 : 2462 Mhz 11g/10Mhz Channel 6 : 2437 Mhz 11g Channel 11 : 2462 Mhz 11g/5Mhz Channel 6 : 2437 Mhz 11g Turbo Since it appears that everything is in place to support it, I'm curious whether there is some technical or regulatory/legal reason that this hasn't yet been done .. I'm not sure of all of the tradeoffs of 5Mhz/10Mhz channels @2GHz, I know that one downside is that likely only ofdm modulations will work, an obvious one is that you'd lose half the bandwidth. On the positive side I suspect (as is the case for 900Mhz) one's noise immunity may change (improve?), and perhaps my signal may get a bit more 'punch' as on the access side I'm firing through a fair bit of foliage.
