I have a problem with WiFi.

I have a home wifi network - laptop works, iPhone works.

Nokia N900 - WiFi is broken. Maybe this is because I am using 10mw power??

It works for the web-browser just fine.

BUT

Any application which connects to the internet, doesn't work!

I can't even update the firmware, TuneWiki, or even the weather when I am on WiFi... but can browse the web perfectly.

When I try to use the wifi via an application, it just times out.

Any help??
