Yes, friends, we have internet service at home again!
Last night Dan got a call from our next door neighbor that his modem was working. We tried ours, but no luck. Dan called Comcast and was able to get some information on repairs going on in the neighborhood. He got us onto the list and today at noon I noticed that the modem was working. I plugged in the router but was unable to get online due to setup issues. Dan fixed it on his lunch break, though, and everything is working great!
So nearly three weeks after the storm, my life is finally back to normal.
