I have this up and running, and seem to be able to flash and run v19.07.3 or master, no big issues there. But it seems odd ... wlan0 is 5 GHz, and wlan1 is non-existent? I also try to scan networks for both, and see nothing - so really thinking the WiFi is broken somehow.
Is it really the case that wlan0 is 5 GHz? Or can this be "broken" by the configuration in /etc/config/wireless (i.e. do I need to reset that somehow)? Also, I do see in the kernel log, quite a few lines like the following
[ 39.097996] ath10k_pci 0000:00:00.0: Direct firmware load for ath10k/QCA988X/hw2.0/ct-firmware-5.bin failed with error -2

OK, a bit more "playing" with this . It does seem that radio0 (wlan0) is 5 GHz, and with some searching and changes to /etc/config/wireless, I do appear to have this radio up - scans work, and in LuCI it shows up as " Qualcomm Atheros QCA9880 802.11acn".
But no joy for radio1 (2.4 GHz). I updated the wireless config as well, based on what seems to work for others (in the forum), but after saving the WPA password from LuCI, the section in /etc/config/wireless gets "minimized" down to,
The device shows up as " Generic 802.11bg", but always shows as not active, and cannot find other devices when scanning ... so I'm really thinking it's not working.
