I have a wired connection. And I recently changed my modem to a much newer
one. I've been having issues recently, which seemed to spawn from an updated
vbox. I have ubuntu running as quest on windows 7. After the update of vbox,
my connection would be very strange, at start up of Firefox, everything
would load. After couple seconds or so, the connection would grind to a
halt. Recently, I activate IPV6 on Firefox, and the problem has gotten much
much better, but not completely alleviated. Some pages are constantly trying
to load, but never get there. But thats much better than before. Before I
switched the flag in Firefox, pretty much all the pages would be stuck in
load mode, it was so frustrating.

Specs:
Windows 7 with ubuntu guest through vbox
wired connection straight to the modem, nothing in between.

Windows 7 seems to work fine
Ubuntu seems like there are some issues still.
