[#1]

Hi everybody,

        I upgraded my brand new Sony Xperia S LT16i from its original firmware Gingerbread to ICS thruough PC companion installed on my DEll Latitude E6520. After the uapgraded I reset the phone to factory default settings and from them problem came: it no more could work with my wifi router with which it worked very well before its firmware upgrade, but it can work well with the hotspot from my Samsung Galaxy Tab 7.7! Restart, reboot or reset both router and the phone for n times but the problem remain. Is there anybody could help me to resoulve this Sony headach?

I to am having this problem on an Xperia S (LT26i). I have read many, and I mean MANY posts to this forum and others of this being a VERY common problem and still there is no fix. I did take the advice and my phone went to a repair centre and it came back and I was told that it was irrepairable and would cost more than the phone!! I had only had it for 7 months!! Tied to a contract and had an expensive brick!!

So I have SUS'd it, downgraded it and got the wireless to work only to start using the phone again and it stop working again.

I have got to say that I moved from an iPhone 3GS to what I thought was a decent phone (Sony) and a tried and tested OS. I actually wish that I had never wasted my money and stayed with IOS and Apple. I didn't have a single issue in the 3 years with that phone.

I have subsequently upgraded to the newest Jelly Bean after several other software and OS changes. I got the phone WIFI working again (no hardware replacing, no costly repair)!!!! However again after several days the WIFI will not connect to any 'known' SSID's which is complete crap.

Also WIFI will not turn on unless I do a hard reset (hold power and up volume key and wait for the 3 vibrates). Turn it back on, take out the SIM (the Xperia reboots), then put the SIM back in (the Xperia reboots again) and then WIFI turns on and operates for a day. Then STOPS.....

Just to add I do not have any AV or app running my wireless connections. I have SUS'd, upgraded, downgraded, flashed, factory reset the device so many times that it is pretty much first time boot other than turning off touch tones.

This has to be a software, driver or other issue rather than hardware!!!! If it was hardware it would just NOT WORK. There are also SO many owners of Xperia S devices having this exact same problem/issue that I cannot believe that Sony has an inherent hardware component issue in all the phones.

Has anyone found a way to reslove these issues or is Sony actually listening and trying to resolve them themselves????
