Yea I added a note to that one and will close this issue.

This also happens to me. I am using my Comcast provided router which also acts as the modem. Upon refreshing the server browser, my ventrilo, streaming software, web browser all disconnect. Even Netflix on the TVs cut out for a few seconds. This seems to determine a complete loss of internet connection while the router sorts through the server refresh. Other games allow you to limit the amount of servers refreshed per second to resolve this. This is not happening with any other game I've played so far.

Same issue as everyone else in here. I am running directly connected to my modem, but turns out my modem also acts as a router which is most likely the issue. I imagine it is not built to handle the amount of request coming at it at one time during a browser refresh. I will try to call Comcast to see if the modem can be turned in to bridge mode so I can use a stronger router. If this resolves the issue it must be due to weaker routers not handling the amount of requests.
