Everywhere I searched, this has solved the exact problem I have [look at the thread, linked above].I just don't know HOW to disable these things. It's my Wireless Connection that doesn't work, and the directions I've been able to find have ONLY been for Local Area Connection. The directions at Gateway [http://support.gateway.com/s/Checklists/BPC/ck2007022632.shtml] [steps 7 and 8] are according to Local Area Connection. If you look at the picture links below each direction, you can see what I mean.Someone please help. I've been searching this for two days and am so frustrated =\

are you sure you need to disable these? I highly doubt that is the cause for lack of connectivity. Most likely this could be a bad driver, or bad settings for the driver. Let Vista do the connection settings rather than the application that came with the wireless adapter. You could try this as well. HKLM>System>CurrentControlSet>Services>tcpip6>ParametersRight click and create new Dword32. Name it DisabledComponents with a value of 1This will disable all IPv6 components. Also uncheck the Ipv6 on the wireless adapter properties within the ncpa.cpl
