WIFI Association Rejected

[Castelchariot]

Hi, I got a problem after updating my Xperia tablet Z WIFI to 4.3. I cannot connect to WIFI, I got the message "association rejected". Googled around and it seems the problem is shared also with Xperia Z/Z1 user after updating to 4.3. Not found real solution on the net for this. Waiting a fix from Sony (off course I tried reboot of tablet/router/delete and create teh connection and so on)

Ok, I tried also Update Service and PC Companion, reinstalling the firmware...no way...

I have the exact same problem and I've also tried to restart/repair everything - Nothing works...

I think I am going to downgrade, to have a WiFi only tablet with WiFi not working is useless.

I wonder why there is this problem on both tablet and several smartphones....without solving it!

I'm experiencing the same problem... Sometimes I'm lucky and when I reset my tablet I'm able to delete and re-setup my wifi connection. While it connects, my tablet isn't responsive but after a short while it connects to the network (again only happens on very few occasions). Most times I receive the WIFI Association Rejected notice or my Wifi just toggles on and off before connecting.

So, I have downgraded and now I can connect again to the WIFI. What is not working, it is the backup recovery. I backuped all my staff on the 4.2.2 before updating, now that I am again on the 4.2.2 I wanted to apply the backup but I receive an error, that it is not possible because of some imcompatibilities between the current software and the backuped...no idea which one, it should be the same.

Is there a workaround? Maybe a way to apply the backup manually, instead from Android?

Thank you

Hi i am from India, I got a problem after updating my Xperia ZR WIFI to 4.3. I cannot connect to WIFI, I got the message "association rejected". I tried reboot of phone/router/delete and create teh connection and so on, even my Bluetooth is also some time find device and sometime cannot able to find device. i have mail to service center & also inform call center since 3 week , problem is not solved.

WIFI is very imp for smart phone so if its not working i unable to do basic function with smartphone.

My number is removed by alexdon - no private info on the forum... i am getting crazy with sony service center feedback & support, thry dont just listen & react very very very slow to customer complaint.
