I have a linksys router model # BEFW11S4V4. The problem I have is that it locks up. But here is the weird part it only locks up when I try to stream video. And not just any video only wmv and realplayer. Sometimes it doesn't lock up though and other times it locks up after the streaming is complete. This started happing when I updated my routers firmware to the latest version. I am all out of ideas and any help would be greatly appreciated.
