I've been having on & off intermittent connection issues with my DSL for over a year now. Some months its stable, others its not. But lately it has gotta so bad I've lost connection every 15-45minutes. I have lost count of the dozens of times I've called Centurylink/Qwest tech support for help over the past year.
Power light will be solid, but DSL light will blink when connection is loss. After 2-4minutes it will retrain and get connection again. Sometimes it stays connected for a few hours and loses it again. Other times it would have a marathon retrain spree having only 5-10minute uptime before it retrains.
Even while writing this post I've lost sync and retained =( Maybe someone here can shine more light on what might be the issue.
Instead of pasting a big block of line stat text. I'll provide here a screenshot. »i.imgur.com/D9jDS.png
. From the screenshot you can see I've had so many sync loss and retrains on the connection. I have good SNR/Atten on my line. DSLAM is visible in front of me a lock away from house.
Things I've done with support many many times
-Power cycled modem (oh so many times lol)
-Reverse the phone cable
-Tried new phone cable
-Tried three different modems. Two actiontec PK5000 and One Zyxel pk5001z
-Check for filter (I have none, only one jack and its for DSL)
-DSL modem connected directly to wall jack 2ft away into "line" port of modem
-Modem is not near microwave or electronic equipment. Don't have any cordless phone in home.
-Desktop is directly connected to ethernet port
-Support accused my Desktop as having malware/virus. So I only used my iPad and problem still remain
-They done line condition testing said their end is fine
Things different field tech dispatch done.
-Replaced phone jack in the house. The NID box is basically right behind it 1ft away
-Switched the line pair at DSLAM multiple times to different ports
