No WiFi with 20210219 update

Post by jackinho »

Today I installed the new released 20210219 update on my N2. After that it wasn't possible to activate WiFi in Android settings. Fortunately I made a backup before updating and therefore could go back to the previous version, where WiFi works without problems.

Does anybody else have this problem with 20210219? Is something wrong with this update?

It's a Realtek 8811CU (VID_0BDA PID_C811). It always worked very stable and reliable on previous versions. Normally I have it connected to the OTG-Port.
The strange thing with the new update 20210219 is that it is impossible to activate WiFi in Android settings. It is deactivated after boot and, no matter what I do, I can't switch it on.

Weird. As far as I remember, we've not ported the RTL8811CU driver.
Did the previous 20210108 version have no issue?

No problems with 20210108 version. The only thing is that WiFi disconnects from time to time when the dongle is connected to a 'normal' USB port. But it is very stable on the OTG port.

We've tested RTL8821CU and RTL8811AU dongles and they worked fine on the latest image.
Since we have no RTL8811CU dongle, it is hard to find what's wrong. Sorry about that.
