Hello everyone. I am at my wits end. As the title states, I am without internet connectivity at home. The error in the subject is what I get when I attempt to configure my connection. I cannot even connect directly to my router by going to 192.168.1.1. I cannot even ping it...it tells me "General Failure". I have disabled the network card and re-enabled. Uninstalled NIC and reinstalled. I have reinstalled drivers, rolled back drivers and even done a system rollback. I have tried disabling Bonjour Service, but it is not listed...neither is it listed as: ##Id_String2.6844F930_1628_4223_B5CC_5BB94B87 9762 ##" I have tried the solution found here: kb/299357 (guess I can't post links). Using both the CLI option and the Fix It For Me thing. I've tried to set my IP manually. I have bi-passed my router and gone straight from the modem to the computer. I've disabled IPv4 and/or IPv6. My card shows up in my device manager as working perfectly (however there is a listing with an exclamation point for something called "Microsoft Teredo". When I attempt to enable it it won't start. I then attempt to enable it and Windows tells me it doesn't have any software for it. I am at a complete loss. This all started because I wanted to share resources across my network and I installed IPv6 because it said IPv6 was needed to share resources across a Homegroup. Is there something else I could be missing?
