DSL Line "Dropping" - reboot brings it back

[rstark18]

Hi All.
My Mom is having a strange DLS issues I'm trying to help her with that just popped up a week or two ago. She was having landline issues. She had a service call for that, that fixed the landline for a week. but then it got much worse (static). After the second landline service call the landline static was resolved but as soon as that service call was done she ran into the current DSL issue.
Every couple of hours she gets no DSL service on her hardwired computer. A powercycle of the modem brings everything back to life for a few hours. Again, this started immediately after the call for static on the landline was resolved. She has had this setup for years so I know it's not a config issue. What could it be?
Modem is a Speedstream 4100b. To make sure it wasn't the modem going bad I replaced it with my spare SpeedStream 4100b and she still has the exact same issue.
This has been a problem since the day the landline service was repaired which was a week ago. AT&T did a line test and they say all is good.

audible static, DSL intermittent. Sounds very much like a "bad pair" in the home or more likely from the home to the cross-connect box on the curb somewhere close.

Telco repairmen are infamous for swapping pairs- customer A has a noisy pair so repair takes Customer B's pair and swaps with A. Closes repair ticket. Then B calls to complain, and the juggling continues. This is complicated by lack of record keeping on bad pairs and by running out of spare pairs.

The real cure is to get a cable modem. The reason is that telcos aren't maintaining their outside plant much any more. Not lucrative business.

(Aside: This bad pair issue is why AT&T's copper wire form of U-Verse (the most prevalent) is a joke - trying to shove 30Mbps down 40 year old wire designed for voice not data nor high speed data.)

I'm pretty sure this was the solution for the line tech that fixed the landline the first time. Not sure what the second landline tech did when the static reemerged a week later.
