After the upgrading the Amber + GDR2 updates to my L620, i am finding that Wi Fi connectivity will be lost and will not work once the screen turns off due to inactivity even though in Settings -Wi-Fi - -Advanced - "Keep Wi-Fi on when the screen times out" is checked or ticked.

During that time wi fi logo will still shows connected on the top of the screen and also in the wi fi setting menu.

It will only work again if you disconnect the Wi Fi connection and reconnect again.

Is any body facing similar problem??

I was having an issue similar in which WiFi would not reconnect on my home network. I power cycled the router and haven't had any issues since doing so.
