    Setup: Network consists of a D-Link DI-604 (4 port, 100 Mbps) as wired router with the 3Com SuperStack II (24 port, 10 Mbps) as a hub connected to one port of the D-Link. Using Rogers Cable internet connected to the WAN of the D-Link with DHCP enabled.

    Situation: Connecting from computer (Windows XP Pro SP3) to hub, DHCP works fine and gives all the computers an IP.

    Problem: Connecting from computer directly to router fails and gives limited connectivity. When I disable and re-enable, sometimes connection fluctuates between connected and not connected. Either way, no internet on the computers.

    What's going on? :( Is there a way to fix this so my three main computers can take advantage of the 100 Mbps speed (so my network transfers are faster).

    Do you have the same problem if you disconnect the hub and leave just one computer connected to the router?

    No, when I first installed router, I tested the connections directly and they worked fine. Somehow, the hub is messing things up.

    *bump* anyone have ideas as to why the hub is messing things up for the router? (or there is another problem)?

    Ok try connecting the 3 computers directly to the Router's ports starting from port 1, then 2, then 3. And connect the Hub if you need to use it to port 4 on the Router. If this doesn't work then i'll be damned...because it sounds like the router is already set up to give out IP addresses. So if it gets a Limted Connectivity error that most likely means that the computer isn't recieving any IP configuration from the Router. So you'll need to take a look at the IP configuration properties of the computer in it's connected state. [Connected through the Hub]

    Do a ipconfig command to see what ur IP settings look like. Connect the computer(s) directly to the Router [from port 1] and take a look at those IP settings using ipconfig...you may need to set the IPs that u get when u are "connected" via the Hub, manually on the LAN Card to test if that will get it "connected" while directly connected to the router...If anything..that should work.

    But honestly, ur issue doesn't make sense to me...and am sure it don't make sense to u either..how the heck is it that it connects fine through the hub..but directly to the router is a problem!...that I find strange.

    Well, when you go through the various settings on the router's administrative webpage, what do you see - anything look funny? Fer instance, how many IP addresses is the router permitted to allocate, and how many has it allocated to the switch? Do you have MAC filtering on, and so forth.

    A hub is a half duplex product that broadcast packets to all the ports (except to the incoming port), and it will serve just one computer at the time, so I'm wondering if there is an special setup in the router to make it aware that there is a hub in one of the ports, so this doesn't interfere with the other Ethernet ports.
