In device manager 802.11n Wireless LAN card#2 - McAfee Cor NDIS Intermediate Filter Miniport is listed with a yellow ! and problem code 19. "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available." When I checked for solutions, it said: "Description: Windows was able to successfully install device driver software, but the driver software encountered a problem when it tried to run. The problem code is 19. Files that help describe the problem: C:\Users\tits\AppData\Local\Temp\DMI8598.tmp.log.xml C:\Windows\inf\oem22.inf " First, I tried disabling it, but that didn't help. I checked to make sure my network adapter was plugged in properly. I checked for updates but they were all current. I attempted to delete the UpperFilters and LowerFilters registry values but I didn't see either registry value listed. When I tried to rollback the driver, the button was gray and inaccessible. I uninstalled and reinstalled the drivers, but to no avail. My best guess is that I need to replace the hardware. It does look like the card itself is a little bent as far as I can tell. (The little pin looking metal object looks like it is bent downward.) And because it frequently comes loose, I have pushed it back into its slot multiple times. Anyways, I was hoping to find other possible solutions before I replace the card. Any help would be greatly appreciated. Thanks!
