It seems like you're experiencing issues with getting your Linksys WUSB600N wireless adapter to work on your Windows 7 Ultimate system. Let's try to troubleshoot this problem step by step: 1. Check Device Manager: - Ensure the wireless adapter is correctly recognized in Device Manager without any warning symbols (yellow exclamation marks). - If there are no issues in Device Manager, the hardware is being detected properly. 2. Update Drivers: - Since you've already downloaded the Windows 7 drivers for the WUSB600N, let's make sure the drivers are installed correctly: - Right-click on the wireless adapter in Device Manager and select "Update Driver Software" to manually choose the driver. - Browse to the location where you saved the drivers on your flash drive and select them for installation. 3. Enable Wireless Adapter: - Sometimes, wireless adapters can be disabled by default. Check if the wireless adapter is enabled in Device Manager: - Right-click on the adapter and select "Enable" if it is currently disabled. 4. Check Network Services: - Make sure that the necessary services are running: - Press Win + R, type "services.msc" and press Enter. - Check that services like WLAN AutoConfig are running and set to Automatic. 5. Network Adapter Settings: - Ensure that the wireless network adapter is not hidden in Network Connections: - Press Win + R, type "ncpa.cpl" and press Enter. - Check if the wireless adapter is listed. If not, click on File > Add Legacy Hardware to add it. 6. Power Management: - Disable any power-saving settings for the wireless adapter that may cause it to turn off to save power: - In Device Manager, right-click on the wireless adapter > Properties > Power Management tab, and uncheck "Allow the computer to turn off this device to save power." 7. Reboot and Test: - After making these changes, reboot your system and check if the wireless networks are now visible in the Network and Sharing Center.
