Neither the default browser, nor Dolphin works when I use wi-fi. It just says "processing" or something like that, but they can never finish loading the page in question. Sometimes they even claim that I don't have a data connection, even though I have my wi-fi turned on (and the wi-fi works flawlessly, I can use the Market and other apps without problems). Opera Mini works fine. However, when I browse through my 3G connection, they all work perfectly. What's wrong?
