0xD1 errors are usually caused by drivers (sometimes these also may occur due to hardware), please uninstall your currently installed network drivers, then run Driver Sweeper to remove any files which may not have been deleted by uninstallation process, then download and install latest drivers for this network card.

If that doesn't solve the issue, please post your most recent minidumps for analysis along with complete specs of your system. Regards
