            hello

            you can trigger a rescan from command line using

            sudo iw dev wlan0 scan
            

            note that if it succeeds, there a big amount of information generated (redirect output to a file in this case), if not the output should fit on the phone screen, post the capture here !

                wow this phone has 2 wifi interfaces, amazing. As a wild take, could you try with wlan1 ?
                (Edit wlan2 -> wlan1)

                I take it that you are using 20.04 OTA-11 (stable) ?

                Also this bug is concerning, could you have been hit by it ?

                        If it's global
                        https://xiaomirom.com/en/download/redmi-10x-4g-note-9-merlin-stable-V12.5.4.0.RJOMIXM/
                        Choose the Fastboot ROM
                        But there are specific ROM for models for India, Indonesia, Russia, Turkey, EEA, Global, China.

                          Something broke in stable at some point preventing wifi scanning on Redmi note 9 pro and Redmi 9 (from my testing). Use the ubports installer to reflash and select 24.04/daily and wifi will be working OK 🙂

                            I have two Xiaomi Redmi Note 9 Pro.
                            One for tests (and back up) and one for my daily use. (20.04 several OTA, and actually one on 24.04-1.x Stable and the other under 24.04-2.x)
                            I have flashed with ubport installer more than 30 times each one.
                            Starting from the right Android Stock ROM, I never had any problem with any parts of those phones. All is working well.
                            As UT is talking with Halium (10 in my case) and Halium is talking to previous Android parts left in place during install, the previous Android MUST be the right one. Not near, not another.
                            Now, I can only refer to my experience...
                            My FAI device, the mobile network from Orange.
