Hi, how did you resolve this issue? I also notice my 5Ghz setting always stick to ch44 160Mhz.I also noted the ch 44 bug. If you change 5G settings , it will always drop back to ch 44.
Thankfully i have saved settings before make any changes. So restoring works.
Take note upgraders to save your settings first.
@starhubbros fix the bug
I also notice the 5Ghz wifi connection keep dropping and not available. Is anyone having this issue?
