    I assume your router is 192.168.2.1 ?

    Also post us 'ifconfig -a' from Ubuntu and 'ipconfig /all' from Windows, please.

    Might not be the os ... it might just be wireless. Try to find any differences using Ethernet cable. Wireless is not the best medium to be using for speed and low latency.
    Granted most would be faster than internet connection but ...

    Only real way to tell is to do comparative analysis using some packet capture software like Wireshark..

    Load a page under windows verses loading page under linux while capturing network traffic.

    Compare captures to see where the delay exists.

    Regards,
    Brandon.

    I'll try that when I have more time.
    It's the week before spring break, which means...
    Midterms! Yay!

    I might be able to get this done tonight...otherwise it will have to wait for the weekend.

    I need you to give us these results:
    cat /etc/resolv.conf
    That will give us your DNS servers. We're just wanting to see if they're the same as Windows.

    I am not trying to insult your intelligence, so I apologize if it appears that way.

    Also, some wireless drivers (and I don't have a list) do have known instability issues. I wonder if this is perhaps an example of that.

    Might actually be, I'm also running on 4965AGN. Although when using my ISPs DNS servers it's working fine for me at least.
