Hi,
I'm trying to figure out why, with OpenWRT, I have few channels in 5 GHz band. Before posting here I searched in the forum and in internet, finding nothing of useful.
I'm using an Ubiquiti RouterStationPro with Ubiquiti XR2 and XR5 cards (but I have identical situation with Buffalo WZR-HP-AG300H).
I'm in Italy, and according the European rules these are the frequencies allowed in my country.
This is what dmesg says
[ 150.160000] cfg80211: Calling CRDA for country: IT
[ 150.170000] cfg80211: Regulatory domain changed to country: IT
[ 150.170000] cfg80211: (start_freq - end_freq @ bandwidth), (max_antenna_gain, max_eirp)
[ 150.180000] cfg80211: (2402000 KHz - 2482000 KHz @ 40000 KHz), (N/A, 2000 mBm)
[ 150.190000] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 2000 mBm)
[ 150.200000] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 2000 mBm)
[ 150.200000] cfg80211: (5490000 KHz - 5710000 KHz @ 40000 KHz), (N/A, 2700 mBm)
And this is what iwlist says
root@ApCasa:~# iwlist wlan1 channel
wlan1 16 channels in total; available frequencies :
Channel 36 : 5.18 GHz
Channel 40 : 5.2 GHz
Channel 44 : 5.22 GHz
Channel 48 : 5.24 GHz
Channel 52 : 5.26 GHz
Channel 56 : 5.28 GHz
Channel 60 : 5.3 GHz
Channel 64 : 5.32 GHz
Channel 100 : 5.5 GHz
Channel 104 : 5.52 GHz
Channel 108 : 5.54 GHz
Channel 112 : 5.56 GHz
Channel 116 : 5.58 GHz
Channel 132 : 5.66 GHz
Channel 136 : 5.68 GHz
Channel 140 : 5.7 GHz
So, the first thing I notice is that I cannot use channels 120, 124 and 128. The second and most annoying thing is that Luci let me to chose only 36,40, 44 and 48 channels. Why?
So I compiled my personal and very unrestrictive regulatory file for the "world domain", in order to make a test. This is dmesg output
[ 41.190000] cfg80211: Calling CRDA to update world regulatory domain
[ 41.200000] cfg80211: World regulatory domain updated:

[ 41.220000] cfg80211: (5170000 KHz - 5250000 KHz @ 40000 KHz), (N/A, 3000 mBm)
[ 41.230000] cfg80211: (5250000 KHz - 5330000 KHz @ 40000 KHz), (N/A, 3000 mBm)

[ 41.240000] cfg80211: (5650000 KHz - 5710000 KHz @ 40000 KHz), (N/A, 3000 mBm)
[ 41.250000] cfg80211: (5735000 KHz - 5835000 KHz @ 40000 KHz), (N/A, 3000 mBm)
and this the iwlist one
root@ApCasa:~# iwlist wlan1 channel
wlan1 21 channels in total; available frequencies :
Channel 36 : 5.18 GHz
Channel 40 : 5.2 GHz
Channel 44 : 5.22 GHz
Channel 48 : 5.24 GHz
Channel 52 : 5.26 GHz
Channel 56 : 5.28 GHz
Channel 60 : 5.3 GHz
Channel 64 : 5.32 GHz
Channel 100 : 5.5 GHz
Channel 104 : 5.52 GHz
Channel 108 : 5.54 GHz
Channel 112 : 5.56 GHz
Channel 116 : 5.58 GHz
Channel 132 : 5.66 GHz
Channel 136 : 5.68 GHz
Channel 140 : 5.7 GHz
Channel 149 : 5.745 GHz
Channel 153 : 5.765 GHz
Channel 157 : 5.785 GHz
Channel 161 : 5.805 GHz
Channel 165 : 5.825 GHz
I would have expected also channels 32, 42 and 46. Also in this case Luci permit me to select only few channels, and in particular 36, 40, 44, 48, 149, 153, 157, 161 and 165.
Is it a bug of Luci or what? What about missing channels?
Thanks in advance
