Mandrake10 network problem 1

[jon1117]

I just installed Mandrake 10 last night on my spare HDD. I have a P4 2.4 with a Asus P4P800 mobo that has an onboard 3com 10/100/1000 nic. Everything went fine except internet setup. I have a cable modem hooked into D-Link router and 2 PCs. I setup the Mandrake for LAN with dchp. When it boots and lists the startup sequences for 'bringing up eth0' I keep getting a 'failed'. If I goto the Mandrake control panel and look at my connections for internet it shows I was assigned the proper IP, but under internet connections it says LAN 'not connected'. So i thoughtto myself, OK I had the same problem when installing gentoo with the onboard nic. But, when i open Mozilla and browse the web it works, and i can connect to gaim, and xchat also works...with one hitch. If i have xchat connected to 2 networks, and open mozilla and begin surfing I can watch the lag bar shoot right up in xchat and it disconnects me from the networks...almost like it cant handle surfing the web and chatting in irc at the same time.

Why does it say its failing to bring up eth0 yet i have internet when im booted?

What could be causing the 'time/lag outs' when doing multiple online things?

Could this all be related to it not liking my onboard nic for some reason?

You most likely have an IRQ conflict. Try using your BIOS to move the NIC IRQ to anything else and let plug-and-play resolve the balance. Short of that, you might have a bad driver in the Linux kernel for the NIC chip.

Further down the diagnostic road you might consider:
1) bad NIC,
2) bad wire,
3) bad wall jack,
4) IP address conflict
5) bad kharma,
6) sunspots

Found the problem..I went into Configuration and into MCC/Internet Connection and disabled 'network hotplugging'. Rebooted and it brought up eth0 fine and connections working right now too.
