Cant get the network card working

I have an abit kt7a-raid mother board running win 98 and i cant get my linksys 10/100 fast ethernet network card to work with it. Windows detects it when i first put it in and the drivers installed with no problem. But when i set it up to use my cable modem it just donst work. I followed the instructions the cable company gave me which work fine on my other computers. I dont know whats wrong with it. I tried everything i can think of. The lights on the card turn on but when i run winipcfg to renew the ip address it just hangs for a bit then keeps the incorrect/default ip address. I tried disabling irq holding which was recomended in the manual but that didnt work either. Im gonna try to mess with the irq settings on the bios, but this hasnt worked either so far, all this has done was make more conflicts between the sound card and the scsi card. I have a bunch of free irqs but the scsi card and the sound card both want irq 11 for some reason. But i dont think this has anyting to do with the network card because in the device manager it says this device is working properly.

It was on auto sense. I Tried every other setting too but since none of them worked I put it back on auto sense.

thx for the reply

Im sure I set it up right. I have 2 other computers that work fine on the cable modem. I unplugged one of the old ones so I could plug the cable into the new one. But when I follow the steps it just dosnt renew with the proper ip address. I tried what you said with the ping 127.0.0.1
and this is what i got back

I dont know my isp's gateway address.

If your loopback address is giving you those results, then that means your NIC is working fine and TCP/IP is installed properly. Describe your topology in better detail. Is this computer part of a LAN or is its NIC attached directly to the cable modem?

Here is how im set up. I bought 2 ip addresses from my cable provider @home. I have the cable modem plugged into the hub in the uplink outlet and the 2 computers on outlets 1 and 2. This setup works for the two old computers. The oldest computer i have is a p200 so i was gonna take that one off the network and plug the wire that used to be in that one into the new computer which i did. I copied the settings exactly from the old computer to the new computer. I couldnt find the same exact network card because they didnt have the 10baseT only cards. So i bought the 10/100 one from linksys. It has some extra settings which my other card didnt have which might cause the problem. when i go into network settings and select the adapter and select properties then click on the advanced list i get a list labeled propertiesOnes i have selected are in parenthesis)
here are the properties in the list:
Link Off change= with the options (disabled)/enabled.
Link On change= with the options disable/(enabled).
Magic Packet wakeup = (enabled)/diabled
Media type: = (Auto Sense)/100BaseTX/100BaseTX Full Duplex/10BaseT FUll Duplex/10BaseT

Those are the only things differnt from the card in my old computer.
ill try to get a screenshot of the settings up

Its a linksys 5 port hub. No idea but i dont think it would be autosensing because its only 10baseT. I lost the manual so i dont know for sure.

The problem sounds like it just didnt like your 10/100BT card on that hub. The NIC had to be set to 10BT...probably half duplex
