munkee Posted April 17, 2016 Share Posted April 17, 2016 I have a 802.11n USB wireless LAN card and running a windows 7 pro x64 OS. when I plugin the usb for the lan card it keeps showing up and then disappearing in the device manager. it's like I'm plugin it in then removing it. all my ports are 3.0 ports. it works perfectly on my other computer running windows 7 ultimate x64 that has 2 2.0 usb ports. Is it a 3.0 usb port problem or something else is up ? thank you Link to comment Share on other sites More sharing options...
