|why would one use a usb adapter when the wireless device is already working? |
If it were working you wouldn't be having this problem. Well, if it were working correctly.
Check for newer drivers for your network interface and install them if you find some. If that doesn't fix the issue, uninstall, then reinstall the TCP/IP stack on that device.
If that doesn't fix the issue uninstall the device from device manager and reinstall it.
If none of the above fixes the issue, you'll be needing a new network interface.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
