Xperia TX cannot connect to home wifi after Jelly Bean upgrade

[jiunshyong]

My Xperia TX (LT29i) after upgrading to Android Jelly Bean 4.1.2  using build number 9.1.B.0.411, is experiencing a strange problem: cannot connect to my home wifi. However  I am able to connect to all other wifi access points (public wifi, office wifi etc).  

Before upgrading, I was able to connect to my home wifi with my same Xperia TX phone Android Ice Cream Sandwich and was using my home wifi to download and upgrade to Jelly Bean.

Whenever I tried connecting to my home wifi, I will get this "saved, secured with wpa2"..    The wifi strength shows full bar but when i tried to connect, the signal bar shows 1 bar only.  After that nothing happens.  Just ""saved, secured with wpa2".. 

My wifi router is working good as I am able to connect to it using other smartphones. 

I have resetted  my Xperia TX and wifi router to factory default but am still getting the same problem.

Apparently others have been facing the same issue.       "Wifi problem after upgraded to JB 4.1.2 - Xperia TX"
