NIC woes

I have recently installed a second NIC on my Red Hat 6.1 box. It is an SMC etherpower pci card.
The card works but inconsistently. Occasionaly I will look down and the link light will be off on the back of the card... this is what it says in dmesg:
"eth1:21041 Media information at 30, default media 0800 (Autosense).
eth1:  21041 media #0, 10baseT.
eth1:  21041 media #0, 10baseT.
eth1: No 21041 10baseT link beat, Media switched to 10base2."

What could be causing this?  

Thanks.

Yeah, perhaps, but I need more information. What is the SMC hooked to, a hub, a switch, cable or DSL modem?  Also which SMC Etherpower? Please be specific and provide make & model info.

Model: SMC EtherPower 10 PCI(8432T/8432BT)  

It is hooked up to a dual speed hub.

hope that helps.

Maybe you have a cable problem or you have a defective port on your hub. Try to change the port first. If it doesn't work, take a look to your cable.

It sounds like it's not happy about seeing a dual speed hub. According to the tulip driver page (http://cesdis.gsfc.nasa.gov/linux/drivers/tulip.html) you ought to be able to force the speed with either an "options=12" 0r "options=9". I can't figure out from the page which would be correct for that particular card, experipmet and see what happens.

I agree. It sounds like forcing the speed of the NIC would be in your benefit. That would be my next step.

I suspect your NIC.  Evidently you have a BNC port (thinnet) and an RJ-45 (Cat-5).  It appears that your adapter logic is toggling between the two connectors.  If you have a utility disk, try configuring the NIC for the specific connector (I assume the RJ-45) rather than "auto."  I don't believe the NIC is throttling back to 10 Mb/s and would also recommend trying a different adapter.  Lastly, use a #2 medium pencil to burnish the edge connectors of the card.  I have fixed several problems to include I/O and video adapter.  A little bit of copper oxide can wreck havoc and be cautious not to lift any trace runs.

Digital 00, thanks for the generous grade!  For my knowledge, what actually
fixed the problem: an eraser or a new
NIC?
