I'm trying out 12.10 - installed yesterday, all updates applied and the wireless connection keeps dropping randomly. It appears to still be connected in Network Manager but I get no response from web pages and can't even log in to my router home page. Clicking on the network manager and selecting my wireless network gets me back up and running.

I have a Broadcom BCM4313 in an HP G62 laptop using the brcmsmac driver.

I had a look on the forum but this didn't come up in any searches so I apologise if this has already been discussed. Is anyone else having issues or does anyone else know of a fix on it's way?
