This is what I have in mine and I just spent 20mins trying to get my WiFi to work to reply. My wifi hasn't worked in weeks and I'm now out of data

I'm the same. Only temporary solution is turn the airplane mode on and off to get the stable Internet for about 15 mins before it slow down. Sony support acknowledged that the Jan security update is the culprit behind the WiFi issue and will working on a fix in upcoming update but I have no idea how long it will be. 😕
