Looks like I found a solution. This problem is listed in bugzilla as bug 1636. It'ss the sleep timeout for wlan, and after entering the command in xterm, my browser now goes forward and back without the blasted hangs and stalls. In fact this post has been written with my n800 as it's now become the device it originally promised! If your browser occasionally says connecting... when trying to move in liinks or back/forward functions, please try this fix. Edit: looks like this post failed just as before. Back to the drawing board.
