Hi JCMTemple,
Dell has not tested this computer with Windows 7 operating system and the drivers for same are not available for this system. I did some research and found the wireless drivers for Windows 7 which I shared with you earlier. However, if those are not working, you may try installing the Vista drivers (shared by you initially) in compatibility mode and see if that fixes the issue.
- Right click on the downloaded file and click on Troubleshoot Compatibility
- Next, click on ‘Troubleshoot Program’
- Click on Program worked in earlier versions of Windows
- Click on ‘Windows Vista’
- Click on ‘Start the Program’
- Do not hit ‘Next’ until the installation completes
- Once the installation completes, click on ‘Next’
If the issue persists, you may uninstall the drivers and try to manually update the Windows 7 drivers (shared by me earlier). You may follow the steps below to update the wireless card drivers manually :
- Download the driver file and extract to a specific folder. By default it will be extracted to C:\Dell|Drivers\R295615
- Open Device Manager
- Right click on Network Controller and Click on update driver
- Click on Browse my computer for driver software.
- Click the Have Disk... button
- Click the Browse... button
- Navigate to the folder that you extracted the drivers to. Default is C:\Dell|Drivers\R295615\Drivers\Win7\WL
- Select the driver file and click on Open
- Click on Next and wait for driver installation to finish
- Once done restart the computer and check if the wireless works.
Hope this helps. Please reply with the findings.
