I installed the snapshot build for Xiaomi Redmi AC2100 and everything works but often my 5G wireless network doesn't work / even show...
I got two phenomenons going on - both happening some time after a working 5G network runs:
- Very often - the 5Ghz network doesn't even show - I've attached an image of the view, it's enabled and should be working but doesn't appear in any of the devices I see
- In other cases, I can connect, get a DHCP address, but nothing works, not even ping to 192.168.1.1 even though the network is connected (tested on laptop and phone).
I tried changing the bandwidth from 160Mhz to 80Mhz and now 40.
Tried to change the channels.
Tried to change the country (I'm from Israel, but tried US, Europe...) - didn't help
Tried to restart the MediaTek MT7615E 802.11nac radio device - Partially helped - on some devices this started to work while in others it doesn't but again after some time was back to not working.
Need to mention that 2.4Ghz works flawlessly during these case.

Any help or ideas for extra data?
