If you're talking about weak signal on some routers, browsers hanging etc. - unfortunately this problem hasn't been completely resolved with 434 update. I think we might need to contact Sony about it because it's very frustrating.
Hint: for now, try setting your router to 802.11G mode. It helped me a lot - seems like XZ is having problems with 802.11N or mixed N/G networks.
I am experiencing bad wifi reception,my router is Netgear N150.Its working fine with my macbook pro ,desktop, galaxy tab2 and ipad4.It was fine with my iphone 5 too.Xperia z is finding it difficult to connect to the same wifi network ,in the same situation.Also if mobile data is kept on occasional shifting between wifi and mobile network occurs.I feel that,wifi reception of xperia z is NOT good.

Hi,
I use only WiFi on mine, and not much problems.
I use the WiFi Alarm app so that if it does get disconnected, I'll beep really loud and alert me to solve it (Otherwise I might not get VOIP calls and not even know I am missing them!)
Like once or twice a day it disconnects for about 0.5 seconds and triggers the alarm, which is annoying, but no major problems. (It reconnects on its own, and it may be the router's fault).

WiFi Dropouts & Issues

Having read around the forums, it seems that wifi problems seem to be an issue.
What are the symptoms people experience? I never had any issues for the first few months. My Wifi will show as connected and I'll have no connectivity (even though it's showing the wifi icon) shortly after it will lose the icon, go on 3G and then connect back to wifi thus repeating the cycle every few minutes.
The WiFi drop when the wifi range is low.Happens to me right now. :/
The WiFi fix by gm007 fixes that issue.(root needed)

Wifi drop fix without any battery drain.
But it got fixed in update 253.
I'm running 307 now and there are no drops in wifi.
I'm on 307 and still getting constant dropouts.

Sometimes me too. Running .253
Actually i started getting wifi drops once again on 307, so i used the mod mentioned above and it got solved.
The OP of the thread i mentioned says there are new drivers for wifi available for XZ so hopefully they get solved in the next update.
But my wifi is pretty good with the mod applied so no worries.

[Q] Working 4.1.2 Wi-Fi Fix?

I am on 4.3 right now but cannot live with the battery drain, the only issue I had on 4.1.2 was the poor Wi-Fi range and it kept disconnecting, is there a fix for it that actually works?

Wi-fi signal keeps dropping in the M31

Hi,
I notice that if the Wifi has been connected for a while, the signal drops and I'm not able to connect to the internet unless I switch off the wi-fi and switch it on again. Initially I thought it was just an intermittent issue, but it's happening almost daily for me now, and has begun to bother me.
Any one facing a similar issue?

Wifi constantly dropping after 58.1.A.5.441 update [w/ workaround]

My XQ-AT52 (dual sim HK) became unusable after recent 58.1.A.5.441 update. Wifi constantly connects - disconnects every few seconds, and after several tries, it gives up then nothing would show up in wifi list. Tried airplane mode/reboot/factory reset/software repair and no luck.
After hours of desperately poking around settings and google, a weird workaround was found: turn on hotspot first, then connect wifi like usual. It keeps connected and fully working until the second hotspot gets turned off. I guess maybe an overly aggressive battery-saving rule was introduced in the update, wrongfully shuts down normal wifi connections and got overridden by hotspot. But I can't find any proof in logcat.
Hopefully this will be fixed in the next update.
Edit:
Upgrade to 58.1.5.474 did NOT fix this problem.
Upgrade to 58.1.5.530 and problem fixed.
I'm having a related issue with Xperia 5 II (XQ-AS52 Dual), seemingly since the same update 58.1.A.5.441.
For me the problem is that 5GHz networks work fine for around one day, then they get disconnected for no apparent reason. At this point, 5GHz networks won't show up in the list of Wifi networks until I restart the phone. Then I can see and connect to 5GHz again but the same problem re-occurs after around one day. Really annoying !
No issue though with the 2.4GHz networks apparently.
I wanted to downgrade to the previous firmware to confirm my suspicion, but can't find it on the web for my region (EU).
