Good morning olympicfarmer,
Thanks for posting and providing all this information, it helps. I just ran diagnostics and despite the weather at your gateway being fine, I'm unable to communicate with your modem. Let's replace it and see if we can get you back online. I'm shipping you a complimentary modem, please expect it in a few days. Here are instructions on how to replace your modem. You can use the box in which the new modem arrives to return the old one; there's a return label in the outer pouch.
