Help Cannot connect to network or network error after software update

[geoffp]

I have just done a Software update on my HTC Desire HD, now I can't use the my Wi-Fi network, it says it is connected, but all the apps. say "cannot connect to network or network error".
The software information is as follows: Android version: 2.3.3, HTC Sense version: 2.1 Software number 2.36.161.12 (CL52372 release-keys).
The mobile connection is fine, but the Wi-Fi connection does not work.
I have done both a "soft" and "hard" reset, but this didn't solve the problem. Can anyone please help. Thanks

The WiFi threshold in this update was set too low so whenever the wireless signal strength drops below -88db, WiFi will automatically disconnect and switch to the 3G Signal.

I think if you turn off mobile internet whilst connected to WiFi, you should be ok.

Hi,

Sorry, that didn't work, the WiFi connection is strong and stable, but the phone does not get onto the network although they are connected.
