A couple of problems, communication as well as low vectors counts since Jan 1 05:00. 2018-01-03 20:22 GMT visited site due to no comms. Found computer ON, but offline. Neither Restarting the computer nor pulling out the USB modem and reinserting it helped, but I then deleted the existing service profile for the MiFi USB modem in System preferences and then removed and reinserted the modem again and that fixed the issue..
