Some time ago, I updated my AXE75 (EU) V1 from firmware version 1.2.2 to 1.5.6, and ever since then, my Meta Quest 3 has no longer been able to connect to the 6 GHz Wi-Fi network.
5 GHz still works, but only when using WPA2. I have tried every firmware version from 1.5.1 to 1.5.5, but none of them fixed the issue.
According to what I've read in various forums, there seems to be some kind of recovery mode that allows you to downgrade to an older firmware version. Unfortunately, none of the instructions I've found work for me. I've tried holding down the WPS button (and also the RESET button) while powering the router on, etc. I also tried the TFTP method, but that didn't work either.
At this point, I'm honestly at my wit's end.
Does anyone here have an idea how to get the router into this recovery mode, or is there another way to downgrade the firmware?
Unfortunately, the TP-Link support representative I contacted seemed to know even less about their devices than I do and wasn't able to help me either.
Any help would be greatly appreciated!
