The intel proset wireless connection dissapeared

Model 769 have the intel 3945abg chip inside, if you visit the Intel download site you can fetch the latest proset wireless package.
A reinstall solves most Wireless issues.

Alternatively you can download a much older version from the Lenovo site.

Using Intel ProSet Wireless, right? Use Windows utility and it will be fine. I still have not resolved this with ProSet.

If the Intel ProSet application has an icon on the bottom-right of your "system-tray" (the system-tray has the START button on the left and the clock on the right), then right-mouse-click on that icon, and choose 'exit' or 'close'.

Hi
Need to know when you try to search the network in the intel proset , does it find the network name or not . ie. does it see your wireless connection.

Alternatively you can use the following link for troubleshooting

Use the Optional Computer Radio On or Off Switch

If your computer has an external switch installed, use it to switch the WiFi radio on or off. See the computer manufacturer for more information about this switch. If you have Intel® PROSet/Wireless installed, the current state of the radio displays in the Intel PROSet/Wireless main window and on the Taskbar.
