Mine was easy, but leaving it alone for 2 hrs was hard. There was a stretch of 45 minutes where it seemed to be hung.
On the other hand, I spent 3 hrs today why none of my computers, iPad and Kindle would not browse the internet but email and everything else (including iCloud) were OK. It seemed like a DNS failure. After calling Comcast, they said there were no outages, I reset and restored the router from a backup. Everything works now, but was mysterious.
