pci simple communication controller

I have a systemax computer running on a windows xp pro and connected to a small wireless network. The internet connection is intermittent. The network card, a G-302v3 seems to be ok but the system says that there is no driver for the pci simple communication controller which appears with a big question mark next to it in the device manager. Can anyone tells me where to find the driver. Thank you.

 

Virtually every time I've seen this error it's due to a windows modem (is there one installed in your system?) I doubt it's anything to do with your wireless issues. Try changing the channel you're using, neighbouring wireless networks may be interfering.

Regarding the PCI simple controller, look at the motherboard manufacturers website for drivers.
