It’s been reported that some have experienced a ‘slow in network speed (especially at great distances), dropped signals, or can’t connect to network notifications’ when using over Wifi when they have upgraded to the Windows 7 RC from Windows Vista.

To troubleshoot this issue Open the “Network and Sharing Center” click on “Change Adaptor Settings” in the left pane. Now Right-click on the Wireless Adaptor and choose “Properties”, and click the “Advanced” tab.

Before you change anything else start with changing the “Mixed Mode Protection” to ‘RTS/CTS Enabled’.

If you are still having issues here are some of the setting you can change around to try and boost your signal and reliability of the connection:

  • Ad Hoc Power Management
  • Change to ’Disabled’
  • Change to ‘Noisy Environment’
  • Roaming Aggressiveness
    • Change to ‘Medium-High’
    • Change to ‘Highest’
  • Throughput Enhancement
    • Change to ‘Enabled’
  • Transmit Power
    • Change to ‘Medium-High’
    • Change to ‘Highest’

    Remember that changing some of these settings can affect the battery life on a laptop computer. So start with the lease aggressive setting and then gradually increase them if needed to get the performance you need.
