I just pushed a patch into rtl8xxxu-devel which may resolve this issue. There were problems with the 8192eu not handling driver reload very well. It is possible the network scripts you run would trigger the shut down and restart that caused this problem. I would be interested in knowing if this patch resolves the problem for you.

The same problems as with the 8723bu where REG_RX_WAIT_CCA bits 22 and 23 didn't get set in rtl8192e_enable_rf(). In addition it also seems prone to issues when setting REG_RF_CTRL to 0 intead of just disabling the RF_ENABLE bit. Similar to what was causing issues with the 8188eu. With this patch I can successfully reload the driver and reassociate to an APi with an 8192eu dongle.
