So I've been happily using my wireless extender for almost a year (bought 12 June 2023)

It's been great but recently the wireless has been randomly turning off, to fix it I have done the following;

Reset the device on both the wired powerline and the wireless unit
Disabled the power save on the Powerline
Updated the firmware
Factory reset, took it back to barebones to start again tech can get confused now and then.

I am unable to try another plug so a suggestion to try that can't happen.

It's annoying that after almost a year its started to fail. Please give advice at what to try next as I am currently unsure where to go next
