Hi, I'm having an issue trying to get the 2.4GHz radio on my WRT1900AC to work, and I don't think the 2.4GHz radio was enumerated on startup.
I've noticed that even when I manually enter the radio into the configuration file it shows up as a 'Generic 802.11bg' in LuCI and reports that the device is not active. The network that I've associated with it is reporting wireless is not associated.
when I run iwinfo on phy1 and phy0, I get the following output:
root@OpenWrt:/etc/config# iwinfo phy1 info
No such wireless device: phy1
root@OpenWrt:/etc/config# iwinfo phy0 info
phy0 ESSID: unknown
Access Point: C2:56:27:BB:FC:69
Mode: Master Channel: 36 (5.180 GHz)
Tx-Power: 20 dBm Link Quality: unknown/70
Signal: unknown Noise: unknown
Bit Rate: unknown
Encryption: unknown
Type: nl80211 HW Mode(s): 802.11nac
Hardware: 11AB:2A55 11AB:0000 [Marvell 88W8864]
TX power offset: none
Frequency offset: none
Supports VAPs: yes PHY name: phy0
I've also noticed that in the log, there is no mention of phy1 starting, but there is a phy0 startup:

Searching through the log for pci 0000:00:02.0, this is all that's mentioned:

Can anyone shed light on this? I'm guessing there's something wrong with the interface or the driver and it can't instantiate it on startup?
