Slackware / Ethernet Network Interface Card (NIC) problem.
Thanks in advance.
About 9 months back I installed the then current version of Slackware on an older machine with dual CPUs, 1 GB RAM and 2 Ethernet adapters on the system board. I hosted a Mediawiki site from this machine for about a month. So, I probably hardwired the TCP/IP address to catch incoming connections passed through my routers. Everything worked great! Then, I retired the machine for about 6 months.
Today, I brought the machine out and fired it up. I have two routers in series and, instead of wiring it to my 2nd router (like last time), I moved it to the router that is plugged directly into my cable modem. DHCP server is running on this router.
During boot, it pauses a long time after showing the NIC's address, but I did not notice any error messages. After I get into KDE, I cannot get a network connection. I can't even call up the router config windows by keying "192.168.15.1" in the address box.
I go to the NIC properties window and it says something like "disabled" for both the NICs. I select either of them and click "Enable" and it works at something for a couple seconds before saying saying something like "Could not Enable - You must enable this manually."
I don't want to re-install Slackware if I can help it. Is there a trouble-shooting or step-by-step process for resolving NIC issues in Slackware?
