I just updated the firmware for my Archer AX10 router and both my range extenders a RE305 v4.0 and v3.0 don't work. 

I checked and the v. 3.0 is not even supported anymore??? 

The v4.0 has a US fw updare work easy mesh, but nothing in EU. 

Will we get a fw version update in EU soon? 

Will this be only for v4.0?

Overall I am really disappointed by this. I have a functioning solution in my home one day and the next I am two extenders short.
