I called in and got quick and excellent service! I think, ultimately, it was my own router acting hinky - we made progress after a reboot, but importantly to me, my helper at Canon, Charlie, taught me where to go to troubleshoot if it happens again.
Customer service for electronics overall is, I think, beyond terrible (my daughter is on 3 weeks with Apple for a simple phone issue), it is SO NICE to pick up the phone and have a live person who I can understand and who is anxious to help! Great day!
