The AT&T repairman just left, after nearly 2 hours of further troubleshooting. He said he’s never encountered an issue like this. Not reassuring.

He replaced the modem, the card at the hub, and completely changed the line from the box at the front of the subdivision to the hub. Same speed results after each change: 5,100 Mbps download, still less than 100 kbps upload.

He has now kicked this issue up to the “LightSpeed guys”, who handle connection issues from there to the main central hub.

I’m becoming more convinced that this is a case of “bandwidth throttling” and nothing to do with cabling. I also find it interesting that no one else in the neighborhood is reporting a similar problem. Guess I’m the only one in the neighborhood who UPLOADS files. Hmmm.
