Deco M5 will not upgrade firmware
Hi, hoping someone might have some magic tricks or advice to help me get my M5 to update.
The app has told me I have firmware updates for my 3 M5's and I have successfully updated two of three, but the third just will not update. It's on 1.5.6 20210615 00000 and the app prompts me to update to 1.7.3 20230906 59213.
Another issue I have which i presume to be a side effect of this is that no clients are connecting to the outdated Deco, it just sits with a signal strength but otherwise doesn't do anything.
I have tried installing from the app multiple times when prompted and each time it confirms firmware upgrades, but the firmware does not change.
I have tried doing so manually through the app with the same result.
I have tried a factory reset, with no luck.
I have tried the online utility throguh the tplink deco management page without luck.
I also tried a utility which is supposed to work for bricked deco's but it didn't do anything when I tried to reboot it to force the file across.
Any suggestions?
