I have had the 825 for a couple of years now, and it has provided smooth service during that time. And even now, it is back to normal. It crashed during the setup period, when the OBI110 was upgrading its firmware. I say "crashed", because it was totally unresponsive during that time. Once the software update was done, all went back to normal on its own accord. It would have saved me a lot of stress if this possible behavior had been warned.
I am still curious about the multiple OBI numbers. The first one is the original OBI number assigned, I guess, by the factory. It always shows "offline". The 2nd is the one associated with GV, and it is the one that shows up in my OBI, when I go thru the web to view the setup screens... the original number was replaced by the GV OBI number. No problem, but again, if this is normal behavior, a heads-up would have been appreciated. As it was, I was worried that I had done something wrong.
