Back in 2021, i was having issues with wifi which lead to me using a Beta version of the routers firmware to correct the issue. Since then, there have been newer versions of the firmware for the AX50 on the website which I have tried to upgrade with, but ultimately failed. I'm still stuck on 1.1.0 Build 20201013 rel.33896(5553) with the "TPLINK BETA" watermark on the web interface.

Every time I try to update the firmware I get the error 'unable to upgrade'.

I've tried troubleshooting tips from the tp link forums, but no luck.

Is there any way to force the firmware upgrade?

Any help would be appreciated.
