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.
