I have the same problem, and I am fixing it same way is Barrr. However, recently it takes more and more time for little WiFi icon to appear on the tope of the screen (and than I tap on it and click "turn off WiFi).

The whole thing is MUCH anoying, and I was looking into ways how to solve this, but cannot find it.

Funny thing is that this started happening to me after I connected to WiFi network in hotel Intercontitental in Cairo, what might not have to do anything with this, but this is how the whole thing started.

Is there a way to push HP to look into the problem?

To be honest, I haven't noticed missign WiFi Tab, I was only truing to go through HP Wireless and no mather how many times I click on WiFi to turn off, it is not turning off.

Also, I have the same problem if I turn ON the WiFi. iPAQ slows down (practically blocks) and I have all of the same simptomes as with the SR.
