heeeelp: wifi problem after imate sp5 update

[Guest CheckerChecker4711]

I have a Tornado in the VDA II version (means Vodafone branded). I have put on the new imate SP5 update.

Since that I have the following problem: wifi is connecting but if I try to open any web site I get "locating..." and then "the page cannot be found. check the name and try again". Same problem occurs when trying to downlod mails over wifi.

If I try to edit the wifi-connection and go "Menu -> 802.1x -> Menu -> Properties" it apears "cannot log on to wireless network. the network requires a pesonal certificate to positively identify you"

On my router I have tried it with WEP security enabled and configured as open network without success.

I'm really thankfull for any help since I've upgraded to the Tornado just because of the wifi function.
