Hello,
Today I noticed that version 4.8.4 is available again. I would like to ask whether all the previous issues have been resolved—especially the poor Wi-Fi coverage problem.
Would you recommend upgrading now, or is it better to wait?
Thank you very much.
Whilst your AI written post is very polite, there are already various posts on this forum discussing it - and on Reddit - with examples of the problems 
GL.iNet are saying the WiFi changes are intended, so from their point of view it’s ‘as it’s supposed to be’
Someone on Reddit posted that they cannot now set over 100mw for 5G - but then another post states the lowest legal limit (UK/Australia) should be 200mw, or even 250mw for USA.
