So, why would someone's (my mother) cable signal cut out at exactly the same time every day (11 pm), and stay off for several hours? She has ATT U-verse. She gets a screen alert, something about you have lost signal (duh). Happens house-wide on several tvs. She has an upgraded more powerful router, and rebooting it has no effect. The length of time connectivity is lost varies, but the really weird thing is when it starts, exactly at 11 every evening. Anyone have a theory?

Yup. ATT is probably doing work starting at that time. Of course, they won't notify anyone that will be affected.

Having spent most of my working life (30 plus years) as a Customer Engineer for a very large US computer company I have seen this exact situation affect our customers many times.

Wow. Several CSRs from ATT swore up and down they had no idea what could be causing this.

They did fly in some special trouble-shooting technician (after my mother raised hell). He also had no explanation, but did reinstall the router on a higher level. We'll see if it helped.

11 pm sounds like an odd time to shut down the system. Between 2 and 4 am is more like it. But I guess, the maintenance is being done by someone in the East.

Could maybe have some type of parental lock accidentally set on it. Look in the TV settings menu and see if there is a feature where the TV is only available during specified hours.

I would ask your mother to talk to neighbors using same service and ask if there are having outages. Then take next step on trouble shooting.

AHhhhh ... was late when I replied. Never mind.

This may sound stupid. Could there be some sort of environmental issue with the cable whether it is above or below ground?

Reason I ask, our previous house had a phone issue that occurred between about 2-6 P.M. with slight variances, excessive static, sometimes dead. Above ground. Ameritech (pre AT&T) and I went around and around, they blamed everything under the sun, had supervisors involved and I solved it.

I was home during an cloudy cool rainy day when I noticed no static on the line. I checked every line in the house and the interface outside. Rain broke, everything heated up, static again including the interface box. Called the supervisor I had been dealing with, they came out and tested the drop line. Bingo, bad conductor, when the black cable would heat up in the sun (west side of the house) the sheathing would expand pulling the inside cable apart. Drop replaced. problem fixed.

I guess it could be anything at this point. I checked with Mom today, the problem persists. She's insisting on refund for all downtime. I actually like the theory that it's unannounced scheduled maintenance.
