Hi. I have been facing wifi performance issues in my z4 tab after last system update.
Tablet doesn't connect to 866Mbs AC anymore, it just links in 433mbs mode.
The wifi performance dropped noticeably :(.
Solved! Go to Solution.
After trying to fix it doing a factory reset, I decided to repair through xperia companion. Didn't work...
Decided to flash another version via flashtool. Flashed nordic. 378.... It worked, now tablet is able to link with ac router at 866mb/s as before with MM.
