10ec:8172 [System76 lemu2] Wireless connection drops and cannot be re-established

[Colan Schwartz]

Spontaneously, the wireless connection stops working. That is, the applet still shows that it's connected, but no traffic is going through. On attempting to disconnect and reconnect, connection is not possible. It continuously fails. One can only reconnect using the following workaround, or rebooting.

WORKAROUND: sudo /sbin/rmmod rtl8192se; sudo killall NetworkManager; sudo modprobe rtl8192se
