I gave up on AT&T because they could not make DSL work and every repair on the trunk line made it worse.
That sounds similar to the problem I had: Old neighborhood and not enough copper pairs. Now that the people are moving away from POTS lines to cellular and fiber, the likelihood of getting any help with copper is non-existent. A repair request for a copper pair is now weeks away in my area, even for a business.

Thank you to everyone for their input. I will post an update once I know more on the situation...

Default Did you eliminate possible issues?

If you have not already done this you should try it just to prove the concept.
Disconnect the cable completely and run the same transmitters the same way with no cable.
if that shows no signs of interference plug in a small local antenna like the ones you see for sale everywhere or even just a short length of cable with about a foot of shield removed.
try all you can to make the same reference happen without being connected to the cable.
And do this with and without the cable box inline. I would start with just the tv itself to make sure the tv isn't just very sensitive to stray RF
This could give you an idea if the interference is being delivered by the cable or if there is a weak link in the equipment TV, Box etc

Guys just a little update on my interference issue...

Today I ran a temporary coaxial cable lead directly from the junction box on the outside of the house up through the sliding door to the cable box, and experienced no RF interference. I then disconnected that cable and then reconnected the coaxial cable that is in the house walls to the cable box, and again experienced no RF interference. I then connected two other coaxial cable leads that are in use (cable modem and additional television downstairs) with the splitter (leaving three un-used coaxial cable leads disconnected) and again experienced no RF interference. I did several transmission tests on different frequencies and still no more interference. Apparently the RF leak is in one of those un-used cable leads. Anyway, end result is that the RF interference issue has been resolved.

Good process used for t-shoot... and you resolved the problem! And THANK YOU for coming back here with the update. 75 ohm terminators on the end of the unused runs might have solved it as well, but why go to the trouble when you can just disconnect the unused runs (which were acting as antennas to pick up the nearby RF).

Since the buy out of the local Bell System company, normally a Bell company, by AT&T, the telephone and outside plant service and maintenance has gone to crap. The company cost for service has gone way up. AT&T is the worst company I have ever had to deal with.

You call fora service problem and your lucky if you ever see someone show up.

I have filed a number of complaints with the FCC. That gets the attention of AT&T. They are required to answer each and every complaint. Problem is they do a simple tap dance and have managed to side step each and every complaint I have filed. I do end up with a call from some one in Atlanta that explains in B. S. language just why they can't resolve the problem, or tell me the situation has been resolve.

Problem is the original call out problem has not been resolved. So when you do get that call form Atlanta, make sure you get the name of the person and a phone number to be able to call them back. That person will try not to supply their contact phone number at all costs. You will receive a letter in the mail explaining what the company has done to resolve the problem. Problem is it's all a white wash program to make the FCC go away.

Complaints to the FCC do have a long lasting ding on AT&T. When AT&T comes back for rate increases, the FCC looks at the number of complaints and uses that information to base the rate increase amount. So you complaints do have an effect if it isn't a direct impact. Don't forget to contact your state department of public utilities or what ever the state calls that group. They too have input to rate increases by the utility like AT&T.

I can show where there was an auto accident along a rural road and the pole was taken out. The power company put in a new pole and took care of their power wires. BUT AT&T STILL HAS THEIR CABLES HANGING IN THE BREEZE FROM THE POLES ON EACH SIDE OF THE BROKEN POLE. They can't even take the time to lift their cable up and attach it to the new pole. This is becoming a common occurrence around the country.

Have to remember that AT&T just laid off a good number of employees. I am not sure just where this is going to end, but fewer employees has 2 effect. The first one is it effects the bottom line on expenses going out. It effects the profit margin. The flip side of the issue here is it effects the repair response time.

Another picture here is that AT&T is the contractor that First Net will be using to install the new Public Safety radio system that will be country wide. Kind of makes you wonder just how they are going to install this new super duty radio system when they just got rid of a large number of employees.

I smell a rat in Denmark here. Don't know about the rest of you.

Another point I will point out is that I use to have my house phone with AT&T. It was costing me $85 a month. I have my internet service from the local cable company. I bundled my land line service for the house phone with my Internet connection. The cost of my home phone service went to $29.99 a month for the same service and features. It also lowered my Internet connect cost.

Don't sit back with service problems. Become a strong complainer. It does cause ripples through many areas that are a thorn to AT&T. Make them feel some of the aggravation that they are putting you through.

The original post was about Xfinity cable service from Comcast. What did anything in this thread have to do with AT&T?

I agree with popnokick. I would have thought considering that my issue has been resolved, your thank you reply would have been "the closing" to this thread ending the need for any further replies, especially when the reply has nothing to do with the thread subject.
