After a fresh boot, my internet connection works great. If I then reboot the system, when I'm logged in again the internet connection no longer works. I can get it working again by commanding shutdown -h and then booting up fresh again.

I saw a small handful of older posts that were similar, but no helpful replies were given.

I have a dual-boot Slackware 11 / Windows 2000 configuration. If from Slack I reboot to Windows, and then from Windows reboot back to Slack, the internet connection still fails. I need to do a complete system halt to get it working again.

Hi,

I had this issue a long time ago in my laptop. The problem was in the driver that Windows would shutdown the card (or something like that) but when the linux driver kicks in it wouldnt turn it back on by default. So if you reboot from one system to the other you get this but a fresh start would always be successful.

I was using a broadcom card, for your info. My recommendation is for you to run an:

lspci -v

To get your board model and then google using that info to find out if there are any known solutions to the problem.

I have a different card for my desktop now:

04:09.0 Ethernet controller: 3Com Corporation 3c905B 100BaseTX [Cyclone] (rev 34)
Subsystem: 3Com Corporation 3C905B Fast Etherlink XL 10/100
Flags: bus master, medium devsel, latency 64, IRQ 18
I/O ports at c880 [size=128]
Memory at faaff400 (32-bit, non-prefetchable) [size=128]
Expansion ROM at 40000000 [disabled] [size=128K]
Capabilities: [dc] Power Management version 1

Get the 3c905B from there and google. Do the same for your card.

Hope this helps.
