So I noticed the MTU is displaying as 1504, not 1500, this is a unconfigured device (greyed out). I then set MTU to 1500 manually, didnt touch anything else, and it failed to bring any connectivity back online, everything dropped, wifi etc. I let the 90 second cool down expire, but was no auto recovery. I gave it another minute or so hoping it at least reverted the config and then rebooted it, luckily it came back up fine and the GUI said it had recovered.
Just a warning if anyone else see's the same issue.
