Network Controller Driver missing, company not known

Hi, All of a sudden my working network controller's driver went missing. I have dual boot (XP, ME), and it is missing in both OS. Could it be a hardware problem ? Do I need to replace the network card ? I searched for the driver in WinXP installation disc, but didn't find it, though WinXP had earlier configured the Network Cnotroller properly. Any way to know which company's Network Controller do I have on my machine ? Thanks Akash

I was having wireless network problems and I accidently went to control panel and uninstalled the Broadcom Network Adapter. I soon found out that I had a missing driver for network controller. I found this out by going to control panel, new hardware and doing a search for new hardware. Then I was trying to figure out where to find the driver since I didn’t know the make/model etc for the adapter. I went to the gateway site and as I was looking for the serial number (still don’t know it), I saw on the bottom of the computer contains Broadcom Adapter BCM9431MPG. I googled the Broadcom Adapter BCM9431MPG driver and downloaded the driver.

My other option was to go to the gateway site and see if I could find out the driver needed and download it based on the seriel number.

My other option was to open the computer and actually find the PCI slot where the Network adapter was put in and see if the name was on the card.

Note: To search the web, I couldn’t use wireless internet access so I plugged an ethernet cord into my computer and the back of the DSL router to connect to the web.

    It depends what mark of Pc you are using. You might have Intel or Broadcom. If you card is missing in both systems, it might be disabled in BIOS or might be damaged...

    Hello, Try physically removing your NIC from the computer and reboot. Then replace the NIC and reboot a second time. If the card is good your OS will recognize it as new hardware and install the appropriate drivers. If the card is bad it will not see it at reboot and not install any drivers and not appear in device manager. If that occurs you'll want to try replacing the card as your next step. Good luck!

    It could be a bad network card; however, do you have your virus program files up-to-date? Also, do you have any spyware software on your OS and is it up to date? Did you do a virus scan after you updated your virus protection? If it is a bad network card you will need to pull it out if it is a PCI card. If it is built into the motherboard you will need to look up the motherboard manufacture to find out what kind of a network card you have. The manufacture of the motherboard will be on the motherboard. Example: Intel, IBM, Chaintech ect. Good luck.
