help with lots of packet collisions!

hi I am running Mandrake 9.2 on my corporate workstation. The Mandrake machine shares a hub with a Windows 98 machine, and the hub is connected to the work LAN.

Yesterday I lost my Internet conenction and noticed the hub's collision light was on. when I unplugged my network cable from the hub, the light went out and everything seemed normal. When I plugged it back in, the collision light came on again, and LAN activity stopped.

So, I swapped out the Ethernet card for another one of the same make and model. There are still collisions but I can at least access the net.

ifconfig eth0:
eth0 Link encap:Ethernet HWaddr 00:50:BA:45:2C:5A
inet addr: Bcast: Mask:
RX packets:5962 errors:0 dropped:0 overruns:0 frame:0
TX packets:4687 errors:0 dropped:0 overruns:0 carrier:0
collisions:1747 txqueuelen:100
RX bytes:4136373 (3.9 Mb) TX bytes:1860150 (1.7 Mb)
Interrupt:11 Base address:0x4f00

What is causing my computer to have all these collisions? Last night when I went to turn off the computer it was over 38,000 collisions.

Check your cable - it might be faulty. Did anyone step on it ? Is it "hurt" ?

Youmight also want to try using any unused ports on your hub (in case a port is faulty)

So you are thinking it's a hardware problem, not my computer software/ the OS?

OK well I did try other ports on the hub. It didn't help. I have not tried another cable yet, though.

Oddly enough, 6 days later, I only have 8 collisions today. So maybe changing the network card worked, only it took a while??

check for damaged cables, cables longer than 350ft long. Also try a diff port on the hub, if all else fails, replace the hub with a switch.
