BQ E4.5 (OTA-7) and Wifi 5 GHz
I have some problems with one of my BQ E4.5 (runs OTA-7) and Wifi AP of the type AVM FRITZ!Box (at least I found no other router until now with the problem). One of the hints from AVM forum is to switch to the 5 GHz bands, which is "802.11n+a" (while "802.11n+g+b" is 2.4 GHz).
Is this supported by the BQ and UBports (and its Android kernel below)?
Can I see somehow in the logs or elsewhere the actual used connection in the UBports installation?

@guru BQ E4.5 has only Wifi bgn :
Thanks. So, 5 GHz is not an option. I don't even think, that 2.4 GHz is the problem, having around 10-15 APs in the area. And, my 6 FreeBSD laptops and the 3 other BQ E4.5 all connect fine with the AP, only one does not. Any ideas?
I think it's time to debug and nail this down. I found the file
/etc/init/wpasupplicant.confwhich spawns the WPA daemon as:
exec /sbin/wpa_supplicant -u -s -O /run/wpa_supplicant
I will mount the /root in this test device writeable and change the line to:
exec /sbin/wpa_supplicant -dd -u -f /var/log/wpa_supplicant.log -O /run/wpa_supplicant
to gather the debugging output in a file.
It's not necessary to mount /root writable. The proc
initstarts and re spawns that proc when it dies. With a bit of luck you can fire up these three lines from a shell script and get your version of WPA up before
initcan restart its own:
#!/bin/sh pkill -9 -f '/sbin/wpa_supplicant.*' wpa_supplicant -dd -u -f /var/log/wpa_supplicant.log -B -O /run/wpa_supplicant exit
The lines in the log files look promising...
