Windows Vista: Improving Wireless Connectivity

Are you having problems connecting to a wireless network with your Windows Vista computer? This may be caused by the fact that your Wireless Access Point (WAP) doesn't supports Vista's wireless auto-tuning feature. To fix the problem you have two options:

• If you own the WAP, you can try to upgrade its firmware to the latest version. You can generally find these updates on the device manufacture support site.
• If upgrading the firmware on the WAP is not an option, then you can try to disable Vista's wireless auto-tuning feature. To turn off this feature follow the steps below:
• Open the 'Command Prompt' in the Accessories menu with administrative privileges (generally this can be accomplished by right-clicking the icon and selecting 'Run As Administrator'. This can also be done by typing "CMD" in the Search field under the Start menu and press Ctrl+Shift+Enter. Then select Continue in the User Account Control dialog box.)
• In the Command Prompt type: "netsh int tcp set global autotuninglevel=disable" then press the Enter key. You should see a response that says 'Ok.'

You will have to restart your computer to apply the change.

Note: To reverse this change, in the Command Prompt type: "netsh int tcp set global autotuninglevel=normal" then press the Enter key. You should see a response that says 'Ok.'
