cascading a hub

[GTSwift]

I am adding another computer to my network. But only two ports work on my router work so I wanted to stack a hub to the router. I set the hub to "cascade" and it acts like it is getting a connection to the router(both units connection lights come on). But as soon as a computer on the hub boots up the collision light come on the hub which then partitions the router off so it can't be seen.

should I get a crossover cable and forget about the casscade switch?
Or I am doing something else wrong.

Are you trying to connect a true router to a hub? If so, you won't need a crossover since router to hub/switch uses straight-through cabling. But, since you get a link light (which I inferred from your post) that's probably not the case. Do you perhaps have one of those Linksys router/hub combos?

Either way, if you're connecting a PC to that hub and it goes nuts with collisions, make sure of a few things:

1. You have the latest (and correct) NIC driver for that PC.
2. Hard code your speed to 10Mbits and the duplex to HALF.
3. Try a different straight-through patch cord from the PC to the hub.
4. Make sure you're not using DHCP unless you have a DHCP server on that network. (It's a long shot but maybe it's going a little nuts on it's DHCP broadcasts and it's getting "mad" that it can't find a DHCP server)
5. Try a different patch cable between the "router" and the hub too.

It's a moot point now but it was a SMC barricade router/switch combo connecting to a plain 5 port hub. About 6 hours after I made the post the router finished its trip south. So I guess it was a problem with the SMC barricade.
