It turned out my IPv6 problems were caused by my router however, I documented a fix at http://jetpackweb.com/blog/2010/05/05/netopia-routers-slow-dns-and-ipv6/ Hey Johann, thanks for the reply and those suggestions!

As it seems to me it is a WiFi subsystem or even kernel regression. There also seems to be an IPv6 issue, but as has already been noted, simply disabling IPv6 does not help. I narrowed down the problem, and in case you connected by WiFI please try the following: When speed is slow: disable WiFi re-enable WiFi and wait for re-association with AP. Is speed back to normal? Also see http://ubuntuforums.org/showthread.php?t=1473022&page=3 and http://ubuntuforums.org/showthread.php?t=1487039 If it has helped, it won't last for long, speed drops back to painful slow after some time. Consider assigning yourself to https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/581936 to raise awareness.
