Frequent Downtime

I've been having problems for the last few years. Everything will be working fine, perfectly stable connection, and then the RG will flash with a red light for about 10 seconds, switch to a flashing green light for another 10 seconds, and then reconnect and everything will be fine again. Throughout most of the year it only happens once or twice a week, but every summer (may-september primarily) it will start happening more and more often. As of right now it has been happening about 3 times an hour, very inconvenient.

 

I downloaded UV Realtime a few days ago after some searches, here are some screenshots.

I notice the recommended profile rate is lower than what I have, is it possible that this is the root of the problem? If so, is there anyone in particular to call to have my profile rate lowered, and would there be any side effects? Or is it likely there is some other underlying problem? Also, what would be the reason behind it being so much worse in the summer? AT&T has told me it is sunspots and solar flares, but that seems hard to believe as no one else I know is having these problems. 

 

I'm in Texas, DFW area, A/C runs all year round so I doubt it is the culprit, no major appliance changes. I've had quite a few people out to check lines over the years to no avail, but I don't recall any specifics as to what, if anything, was done other than swapping out the RG a few times. 

 

Thanks for any help you can give.

I live in North Dallas and I have the same issues.  I had this issue for years also and it seems to be getting worse.  I got to a point where I stop calling ATT becuase they don't seem to know what the problem is.  I'm looking to dump Uverse and go with someone else soon.

Guideline,

 

You have several problems with your line.  You're on the wrong profile, for one thing.  Second, it looks line you either have a bridge tap or other form of line interference.  The Bitloading looks abnormal in the high end along with the large dropout in the low end, and the Error table is a complete mess.

 

You should contact tier 2 and have them send a senior tech that can look for and eliminate possible sources of interference. Possible sources include:

* Power line interference, such as:
* Fluorescent light ballasts
* High-intensity gas discharge lights like mercury vapor
* Grounding problems, such as improper ground at the NID, the pedestal, etc.
* Electrical system grounding problems, such as improper ground on the RG's outlet, the breaker panel, etc.
* HAM radio broadcasts in the HF band
* AM radio transmissions, such as a nearby radio station

Try to isolate any potential source of these problems and see if you can find one that eliminates the interference.

 

A bridge tap is an extra length of wire attached to your pair that doesn't terminate anywhere. It is usually left over from a previous customer that used your pair. Bridge taps cause problems with xDSL services.

You should call technical support, have them send a premises tech to your house to check the line. He should open a helper ticket with the Installation and Maintenance group (I&M), which are the linesmen, to come find and remove the bridge tap.
