I have a laptop using Vista. I usually use IE (7) and wireless connection for internet browsing.
It works well except that when I try to access certain website, it will fail. There's not any error message, just there's no response. Afterwards, all internet connections will be hanged. And I need to reboot the laptop and the router to get things normal again. However, if I choose to use my laptop with a LAN connection, it can connect to the specific website without any problem. What's wrong about it? It seems the specific website will hang the wireless router. The brand name of the wireless router is "Buffalo". Anyone can help? Thanks.

Check your router config. I am not familure with the software on Buffalo routers it may be a security issue or an issur preseaved as a security issue by the router. If it is only one site Iwould suspect the site. Not knowing the site I would advise against changing any settings or security features to allow the site to run.
