Hello!
I have a 6Mbps DSL connection with centurylink. I've had it for about three years, and over the last year it often becomes unstable, and even unusable. I have had atleast 10 technicians come out, and spent many hours on the phone trying to get the problem resolved, none of which has led to a fix. I have recently had my drop line replaced, which had no effect on the connection. I have replaced the C1100z router/modem three times, and it has had no effect. I do live out in the woods, and I've been told by some of the techs that the CO is about 2 miles out. A couple of the techs that were independent contractors straight up told me to deal with it, because 1) centurylink doesn't care to replace the old copper line and 2) i'm too far away from the CO for a stable connection. Other techs have told me that is not the case, and the connection was more stable when i first moved in a few years ago, so I am still hoping for a fix.
The connection will sometimes work for several hours at a time, and VERY rarely, a whole day. Most of the time though, it will work for 30 minutes or less before I see the SNR drop, and the CRC errors begin to accumulate at a rate between 50-500 every 10 seconds. Sometimes this leads to a line retrain, and it will work when the modem has cycled. Other times it will continue to error until i power cycle the modem, where the whole process repeats. Other times it will not resolve until I factory reset the modem, and other times still, even that won't resolve it and there is nothing I can do.
My main questions are thus: How can the line work so well at some times, and so poorly at others? If the line was damaged, wouldn't it be unable to support a solid connection at any time? Could the connectivity issues be related to other subscribers in my area using their service at the same time? Also, with stats like this, is it DEFINITELY a line issue, or could this be related to my router, and might I benefit from trying a different make such as Netgear?
I am currently in contact with a branch of Centurylink called "Crucialcare" that deals with problem connections like this, and I am waiting to hear back from the agent I'm working with, as he is reaching out to the local supervisor.
Any information or suggestions are welcome and appreciated. I have had to learn a great deal of patience from troubleshooting and dealing with this connection, but I would still like to do everything in my power to resolve the situation. I'll attach some screenshots of what the DSL stats commonly look like when the connection drops, but bear in mind that the SNR can vary anywhere from -2 to 12, and that the CRC errors accumulate at a varying rate as well, sometimes more, or less than what I've posted. Please let me know if there is any other information, or other screenshots from the modem GUI that would be helpful to post.
Note: The first image is typical of a connection failure. The second and third attachments are from this morning, when it is strangely acting fine with NO ERRORS (very rare)
Thanks for taking the time to read!
