Fixing: Windows Vista won’t connect to the network

I found an interesting post “Windows Vista won’t connect to the network - how to fix the problem by making Vista less aggressive on the network” by Steve Lamb.

Windows Vista automatically tunes it’s network settings to make the most of the available bandwidth. In some scenarios Windows Vista can fail to connect to the network - this is often due to old routers which don’t always quite follow the standards to the letter. There is an excellent white paper titled Windows Vista TCP/IP Networking and IPv6 Migration that explains in quite some detail how Windows Vista tunes it’s performance - it’s well worth a read. The white paper explains the rationale behind the default settings and the implication of making changes.

If you find yourself in a situation whereby you are unable to access a network then it’s worth trying the following from a command line that’s running with elevated privilege.

Note: An easy way to run an elevated command line is to create a shortcut to “cmd.exe”, right click on the shortcut (whilst logged in as an administrator) and select “Run as administrator”.

To view the current TCP optimisation settings issue the following command:

C:\Windows\system32>netsh interface tcp show global

    You have to run CMD as administrator. Shift right click and run as admin. This still did not help me anyway. I still can not connect to my home network but I can get on other linksys netorks.
    Good Luck

    Kon - Right click on the Command Prmopt icon on your start menu and choose “Run as Administrator” - this will give you the elevated rights you need.

    If I can find this site again, I’ll let you know how this fix gets on. So far I’ve tried to disable IPv6, QoS and more and Vista still randonly disconnects.

    A quick fix to save rebooting is to disable and re-enable the adapter.

    Operation requires elevation is because UAC is switched on. Switch off UAC under your name in User Accounts before you try.
