Wifi Issues after upgrading to ICS 4.0.3

[#1]

Dear Forum Members,

Recently I have upgraded my Xperia Neo V to ICS 4.0.3 from ginger bread 2.3.

I am facing issues with my wifi connectivity, I am getting signals and able to connect to a particular router, but not able to surf internet.

Is the problem persists with my mobile hardware or there is some issues dut to ICS 4.0. I was able to use wifi with ginger bread excellently.

I hope, somebody can help me out to resolve this issue, my phone is not rooted as it is still under warranty.

Today I have updated my Neo V with ICS 4.0.4

But wifi issues were same as before with ICS 4.0.3.

Then I reset by phone to factory settings, erasing my all previous data.

That really worked out for me, now I am able to use wifi.

Users having problems with WiFi usage with ICS 4.0.4 shall try this solution once.

I did the upgrade to ICS today, with my Xperia pro. Same problem, refuses to send data over Wifi.

Edit: Using ICS 4.0.4

Edit: Now I've tried the Wifi with a different router, and that works. So it probably is some issue with DHCP-leases or so.
