I'm running Vista Home Premium 64-bit on a Gateway M-6864FX laptop, and I'm unable to get internet via wireless or ethernet. It said it was there was a problem with my IP configuration, but upon checking the properties of my wireless adapter, where normally ipv4 and ipv6 are located in the list, there was nothing. It wasn't present in my wired adapter's list either. I clicked the install button and was able to install ipv6 back without incident, but when I try to install ipv4, it says "Could not add the requested feature. The error is: Access is denied." The image attached is the area I'm referring to where ipv4 is missing from. I've tried using netsh.exe to reset my IP "stuff" and winsock, but after restarting, nothing is different. I've uninstalled and reinstalled my driver for both my wireless and wired adapters. I've scoured the web and found a very small few articles of people with the same problem, but none of them have found a solution. Can anyone here think of anything else that I might try? Thanks in advance for any help I receive. I can provide any additional information that might help you to diagnose my problem.
