Windows 7 Win7 disabled wireless network adaptor interface automatically and was unable to enable it until reb

[ihatewin7]

Hi All:
I met a big problem in Win7 and can't find the related solution or MS update on the internet.
I have a wireless device (USB interface).
Win7 system can detect it and I can use it to connect network successfuly.
However, sometimes Win7 will automatically disable it forever and unable to enable anymore (from Manage Netowrk Adaptor) when I unplug and re-plug in it, but the device can still be found in Device Manager .
In this case, the device can't be enabled anymore even I tried to use "netsh interface set inferface..." to enable it. The only way to use the device is reboot computer.
Does anyone meet the same problem? Do you have any idea?

My operations:
(1) Login Win7 (administrator)
(2) Plug-in my wireless USB device
(3) Connected to network
(4) Unplug wireless USB device
(5) The device will be disappered in both "Manage Network Adaptor" and "Device Manager".
(6) Replug-in device
(7) *Sometimes (1/2 rate), the device adaptor interface will be automatically disabled from "Manage Network Adaptor", but it is still available in "Device Manager". It is unable to connect network anymore since the interface is diabled by Win7.
(8) Reboot computer, it backs to (1)

Please help I will deely appreciate it. Thank you.

It seems like you're facing a challenging issue with your wireless USB device on Windows 7. The problem where the device gets automatically disabled and cannot be re-enabled without a reboot can be frustrating. Here are some steps you can try to troubleshoot and potentially resolve this problem: 1. Update Device Drivers: - Ensure that you have the latest drivers for your wireless USB device installed. Sometimes outdated drivers can cause conflicts or issues with device management. 2. Power Management Settings: - Check the power management settings for the USB device to ensure that Windows isn't turning it off to save power. - Right-click on the device in Device Manager, go to Properties, and under the Power Management tab, uncheck the option "Allow the computer to turn off this device to save power." 3. Registry Check: - You can also check the Registry settings related to the wireless device to see if there are any settings causing this issue. - Be cautious when editing the registry. Create a backup before making any changes. 4. Disable Selective Suspend: - Disable the Selective Suspend feature in Windows. This feature can sometimes cause issues with USB devices. - Go to Control Panel > Power Options > Change Plan Settings > Change Advanced Power Settings > USB Settings > USB Selective Suspend Setting > Set it to Disabled. 5. System File Checker: - Run a System File Checker scan to check for and repair any corrupted system files that might be affecting the device's functionality. - Open Command Prompt as an administrator and run the command: sfc /scannow 6. Disable and Re-enable the Device: - When the device is disabled, try to uninstall the device from Device Manager and then unplug and replug it to let Windows reinstall the drivers. 7. Check for Windows Updates: - Ensure that your Windows 7 system is up to date with all the latest updates from Microsoft. Sometimes updates can include fixes for such issues. 8. Check for Conflicting Software: - Some third-party software or security tools can interfere with the proper functioning of devices. Temporarily disable any unnecessary software and check if the issue persists. 9. Hardware Issue: - It's also possible that there could be a hardware issue with the wireless USB device itself. Try using it on another computer to see if the problem occurs there too. If after trying these steps the issue still persists, it might be beneficial to contact the manufacturer of the wireless USB device for further assistance or consider upgrading to a newer operating system that is fully supported with the latest drivers and updates.
