I just had a very pleasant experience with Comcast customer service. I didn’t know that such things existed anymore. The tech was local to me, completely patient, and walked me through a dozen troubleshooting steps. As we did them, he explained why each step was valuable and what we hoped to learn. It turns out that our router may be feeling its age, but because the guy was so helpful, I now know how to do the electronic version of kicking it to make it start again. Yay.
