22.1 Legacy Series / Wireless issues - WLE200NX (Atheros AR9280) - no 5Ghz option

« on: May 07, 2022, 01:46:16 am »

Hello

I have migrated my pcengines to opnSense today, I have a WLE200NX a/b/g/n wireless card (https://www.pcengines.ch/wle200nx.htm). I recently moved from an older version of Pfsense 2.4.5 which I could use 5GHz, I was using channel 36.

The settings I have are:

[Common wireless configuration - Settings apply to all wireless networks on ath0]
 Standard 802.11ng selected, "802.11na" is missing from the list....

[Network-specific wireless configuration]
the Mode is Access Point


Can't select any channels in 5Ghz and can only see 2.4Ghz

Using SSH I can see the other channels are available:

Code: [Select]

root@OPNsense:/ # ifconfig ath0_wlan1 list channel
Channel   1 : 2412  MHz 11g ht       Channel  11 : 2462  MHz 11g ht
Channel   2 : 2417  MHz 11g ht       Channel  36 : 5180  MHz 11a ht
Channel   3 : 2422  MHz 11g ht       Channel  40 : 5200  MHz 11a ht
Channel   4 : 2427  MHz 11g ht       Channel  44 : 5220  MHz 11a ht
Channel   5 : 2432  MHz 11g ht       Channel  48 : 5240  MHz 11a ht
Channel   6 : 2437  MHz 11g ht       Channel 149 : 5745  MHz 11a ht
Channel   7 : 2442  MHz 11g ht       Channel 153 : 5765  MHz 11a ht
Channel   8 : 2447  MHz 11g ht       Channel 157 : 5785  MHz 11a ht
Channel   9 : 2452  MHz 11g ht       Channel 161 : 5805  MHz 11a ht
Channel  10 : 2457  MHz 11g ht       Channel 165 : 5825* MHz 11a


Code: [Select]

root@OPNsense:/ # ifconfig ath0_wlan1 mode 11na
root@OPNsense:/ # ifconfig ath0_wlan1 channel 36


Code: [Select]

root@OPNsense:/ # ifconfig

So the card works fine in 5Ghz it is just the interface that does not allow this...



Update: I can see that someone has raised a similar issue with an old version 19.1 previously here: https://forum.opnsense.org/index.php?topic=12755.0 and it was fixed in 19.7...could this be a regression bug?
