I have been having a problem for quite awhile and I've just been tolerating the nuisance until now. I don't know if it has something to do with a cable line sending bad packets to my network from the cable company, but I have a hub that is colliding very often. Here is my network layout. Linksys Router takes the main cable line and splits the signal to two computers on the first floor of my home directly. Now, on the second floor I have one line coming up on the side of the house which goes to a Linksys Hub. That line then splits the signal into 2 for two workstations on my second story. Now, one workstation most often times is never connected, as the Cat5 cable just kinda sits behind the desk unless I have to repair something. Now, the other one is on the second floor in my office, which is the same room the hub is in. The collisions occur pretty frequently which causes lag spikes that will shut down programs momentarily and start them back up again. It's a very annoying nuisance. I haven't really configured much in the router itself other than port forwarding. Can anyone give me any assistance? All help would be appreciated. I would just like to figure out if it is my network configuration or if I need to call my cable company and get it straightened out by them. Thanks in advance.

The problem is with the hub. A hub is pretty dumb piece of equipment and will tie up the network evasively as it doesn't so any packet direction like a switch does. First think to do is make sure you NIC are configured for half duplex. Hubs don't work to well on full duplex. Also make sure that speed on the NIC is set to Auto detect. If you still get a lot of collisions, consider replacing the hub with a switch. That should eliminate collisions almost entirely. Stuart
