BBBW wifi issue with 10.5 buster console image #68

Hello everyone,

With buster 10.5, when the wifi is idle (nothing connected), it stops working after a while, about 15 minutes.

With connmanctl (USB):

connmanctl> technologies /net/connman/technology/p2p Name = P2P Type = p2p Powered = False Connected = False Tethering = False /net/connman/technology/bluetooth Name = Bluetooth Type = bluetooth Powered = True Connected = False Tethering = False /net/connman/technology/wifi Name = WiFi Type = wifi Powered = True Connected = False Tethering = False connmanctl>

Power is on, but no result with "scan wifi" and "services".

Need to:

connmanctl disable wifi connmanctl enable wifi

To make it work again.

However, when I'm connected on wifi, it's stable. Hard to know where is the problem, The power management is off with iwconfig.

$ sudo iwconfig SoftAp0 IEEE 802.11 Mode:Master Tx-Power=20 dBm Retry short limit:7 RTS thr:off Fragment thr:off Power Management:off

wlan0 IEEE 802.11 ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=0 dBm Retry short limit:7 RTS thr:off Fragment thr:off Encryption key:off Power Management:off

No problem with the 9.12 Stretch image.

Thanks,

Hi @sreipro this is a v4.14.x-ti -> v4.19.x-ti regression, I've never been able to fully solve what's causing it to go to sleep.
