I bought my sonyxperia a month ago and every thing about internet connection was just fine suddenly after i received that there is a new updating system i clicked it and it updated the software then i tried to connect to my home wifi it didn't detect it even other devices and phones detect it  and it's working well  ! i  even tried to open my 3g it didn't connect !!! i don't know what to do

turn your phone off..take battery out for some minuetes..then turn on phone and see how it goes

if it doesnt work you can try reset to factory...but keep in mind all of your data on internall storage will gone..so backup if you want

do as i suggested above...if problem persist you can repair your firmware using either SUS or PCC

Sounds like your firmware needs to be repaired but in doing so will factory reset your device meaning any data etc will be lost - To run a repair 1st make sure your phone is fully switched off and disconnected from your Pc then start PC Companion and click on Support zone then click on Update my phone/tablet then in Blue click on Repair my phone/tablet and when prompted hold volume down and connect your USB cable to your phone from your Pc - This should begin the repair process
