How to communicate with anyone with a clue?
A while ago the power company replaced a series of power poles that also supported Comcast cable. Surprisingly, our service wasn't interrupted. A few weeks later - about when I expect that Comcast restrung the temporary cable supports, my incoming signal strength dropped 15dB. It's still - barely - within spec but once the weather warms up it will no doubt be out of spec.
Trying to contact support: 30 minute wait, then someone who repeats my question in more-or-less my brand of English, then offers to reset my modem. Me: PLEASE do not reset my modem, the problem is outside in the neighborhood and I'm trying to give you a heads-up. She: resets my modem.
Outside tech have always been awesome. Phone support... ghastly.
