A couple of days ago, I noticed that my 1Gbps nominal Comcast service was down to ~90Mbps. I spent an hour with them on their automated chat, and then did a couple of things, and it bouced back up to closer to 900Mbps. But then, this morning, it has slipped back down to sub 100Mbps again. Sigh. And they reset my cable modem out of bridge mode. Anyone have any experience with this?
