Hi, My htc wildfire is able to connect to my office wifi network very smoothly, but strangely it is not able to open any website or internet application. It just says network not available. The signal strength is pretty good, and my wifi router is Linksys wrt54G. I am using mixed mode, with channel 11. Also please note that, the phone connects to my home wifi network, and works well - with the same router (WRT54G). The sites and all applications open well. Please help - what could be the reason, and what should I do about the same ?
