Windows cant detect Network card after Knoppix

[darkcurves]

Just tried Knoppix LiveCD. It worked great. I even browsed the net with it. After shutting off Knoppix and returning to Windows XP. I notice Windows doesnt detect my network card anymore. When i check in Device Manager, there is totally nothing, as if there is network card at all. What could be the problem? Did Knoppix changed any settings for my network card?

Thanks!

I doubt very much if Knoppix changed any XP setting, it can't even write to an NTFS partition. And I can't understand why the NIC would no longer show up in device manager (although we have seen a few rare cases of IP address lease problems when the lease is not returned properly, but that is very different from a NIC missing from device manager).

My best suggestion at this point would be to be sure that you completely shut down the computer that was running Knoppix (don't just do a warm reboot). If that doesn't do it I would also try cycling power on the router (although, again, any problem there would not explain a NIC not being in the device manager). Beyond that we need more information, including both the NIC and the network configuration. Also confirm that Knoppix can still see the NIC if you boot back into the Live CD/DVD.

Thanks for the reply Harry.

Even Knoppix cannot detect my NIC. It's actually built-in the mother board. I tried all sorts of stuff, nothing doing so i just installed a network card. It works but i am yet to test it with Knoppix. Lemme test it out now.

That's very strange. Even if the NIC somehow was failing one would expect most failures to still allow one to see the NIC, not have it completely vanish. However, knowing that it is on the motherboard, I would look in the BIOS and see if there isn't some setting that lets you enable or disable the on-board NIC. Check to see it it somehow got disabled (and check your other BIOS settings too, if the NIC somehow got disabled who know what else happened). And even if the NIC is showing as still enabled in the BIOS, I would take the extra step of disabling it in the BIOS, restart the system, and then enable the on-board NIC again and see if that makes it show up in Windows and Knoppix. There may also be a BIOS setting that restores systems defaults, which might help. BIOS changes are certainly not typical of Knoppix either, but I could believe that something (maybe Knoppix, maybe something else) somehow changed the BIOS setting that says the NIC should be seen more than I could believe that the Windows configuration was changed (and it obviously was not if Knoppix can't see the NIC now either).

Very strange indeed. In addition to what HK suggests, I might completely remove power from the machine, unplug it. Try removing the battery from the mobo as well, which will erase any changes made to the bios and reset it to factory.

What is the make/model of the board?

Well, i tried all sorts of stuff, nothing works, i gave up. Anyway, the network card i installed works great with Knoppix and Windows. Knoppix comes handy when i would like to backup files.

Thanks for all the help guys, appreciate it.
