I am thinking about going from Redhat 9 to one of the new enterprise ones. Theres only one thing stoping me. I had already tried Fedora 6, but is seems like my ethernet card wasn't supported or something, because the connection would connect for less then a minute then it would disconnect, the only way to get it back on was to pull the able out of the card, then plug it back it. After doing that, it would connect for another minute before disconnecting. So I was wondering if one of the new Redhats would not have this problem. Acording to Hardware Browser the info for my ethernet card is Manufacturer: Davicom Semiconductor, Inc. And Driver: dmfe. Can someone give me a response?

The network card thing seems like a minor issue. What is the chipset on your network card. If you get a realtek 8139 based network card, it should work flawlessly with most Linux distributions (and the cards are quite cheap).

Unfortunately, Red Hat does not certify individual hardware components like Network Cards. However, if you can find a system in the Hardware Cert List https://hardware.redhat.com/ that has your NIC, then you should be OK. Otherwise, new drivers are adding to the O/S with each update release. The post above is useful as well, replacing a network card should be minimal considering the other value you will get out of upgrading to a supported O/S.

See what module the version you have now is running for your NIC and you'll want to use the same module in the newer version. Also telling us what type of NIC it is would be helpful.
