[CenturyTel] Using my own modem

Anyone use their own modem with Centurylink?

I am convinced the modem I have from centurylink may be defective. After calling today and hearing from the phone support person that they would have me monitor the connection directly for several days and it would be a huge lengthy process before they would consider sending a replacement, I've decided to start looking into the feasibility of just using my own modem.

I have an excellent router already so I don't need those features- just a good modem.

What's happening to make you think the modem is defective
You can obtain and use a replacement modem

Since I had the service there has been speed issues. Most of which was remedied with some rewiring by technicians that visited. Since the last technician visted- The modem drops speed about 1-2 times a week even with a computer connected directly into the modem. Bridge mode and routing mode doesnt make a diffrence. Except bridge mode is good for getting random speeds. If the modem is turned off then on things get betterish usually. If it is flat out reset with a pen in the reset button it gets better for a week without any problems.

The modem is also very warm to the touch when this happens, more so than any other modem I've had previously.

The speed issues are noticed doing speedtests from the centurylink site and speakeasy. As well as looking at the modems page where it has a status portion that shows the DSL line speed which is proportional to the speed test results.

When I called Centurylink today I spoke with somone who I wasnt very impressed with who made it sound like it takes an act of god to get a diffrent modem.

Sounds like you are having trouble with the dsl line
I'll suggest that you post the dsl line stats

I used the Netgear DGN22000 DSL modem/router for a year, but recently I switched to the TP-Link TD-8616. Neither of these devices are on the "approved" list, but they have worked just fine for me.

I'll be looking into the TPLink. The $28 pricetag has caught my attention. The only other fix I have left other than paying another $85 for a tech to come out and blame the modem or jack, is to have maintanance open up the Demarc box and run a line to my apartment specifically for my modem.

Yea I don't think another modem will help
The noise margin is dropping to 9db I think that is causing your problem
Connecting the modem at the nid test jack will show if there is a problem with the inside telephone wiring

it's the only jack inside my apartment that has any functionality, the others have been "un attached" by the techs who was here previously.

You must be in a condo or apartment that makes self testing/repair difficult or impossible

Apparently instead of wiring each jack outside they just spliced the others to 1 jack inside. I could get to the demarc as it's right outside my window, however it's likely best I stay hands off.

If it would make any diffrence, I'm within a 5-6 miles of centurylinks "DSL building" here.

I did get my hands on another modem at Goodwill for $5. It's an older model 660. Only diffrence is in the downstream attenuation is detected at 34 and the upstream noise margin is 12. It was the same results each time, wheas the modem centurylink gave me waivers. I am going to talk to the building maintanance and see if I can get him to run a line from the demarc to my window (litterally 10 feet) and see if it improves it.

Thanks for the help, I'll let you know how it goes.

Can you post a picture of the demarc and wire splices

The demarc is a metal box outside attached to the wall. I wont be going near it. The wire splices have been disabled. The line litterally runs from the demarc to the jack. I did rewire the jack out of curiosity and it's about the same. I thought about tinning the wire but figured that would be overkill.

PS: After rewiring the jack I am back into the 8.16Mbps/738kbps range which is slight improvement. However the signal strength is:

noise margin upstream: 19 db
output power downstream: 18 db
attenuation upstream: 13 db

noise margin downstream: 11 db
output power upstream: 12 db
attenuation downstream: 26 db

Ok......

Disconnecting the unused wire pairs make the remaining pair a dedicated dsl wire pair

Doing that will not help

That's ok give it some time to see how stable the dsl sync is
Whenever the dsl line gets noisy the sync speed will get lower to gain stability

Lets say the wire in my wall isnt corroded or in some way bad (building was built in 2000), and lets say the demarc box is okay (a tech was just out at it Jan 12th and found no issues). What could cause issues like this? And how do I explain it to CenturyLink?

Once you eliminate any "inside wiring" problems all that's left is the telco wiring and you can't repair the telco wiring

Patti, I'll be emailing you for sure. I talked to the bulding maintanace man who said it's very likely the line in the wall is bad because they did not use very great quality cable in some of the units when the place was built 10 years ago. He did not want to run the line as he admitted he wasn't the most knowledgeable on what he was doing. And calling Centurylink wasn't very useful.

I may have solved the issues at least partially. The jack I and 2 centurylink techs believed was the "main jack" inside my apartment was not the main jack. I discovered another jack behind my sofa that no one had noticed before. I plugged my phone into this mystery jack and got a dialtone. Plugged in the DSL modem and the noise was the same, but the speeds was in the low 7Mb range more often than it broke the 8Mb range. The receptical where the wire plugs in at was a little on the start of corrosion and it had the blue wire with the green wire, the white and blue with the wire and green. The screws that held the wires in place was on the loose side as well. I replaced the jack and wired it identical to the other jack. However I did not continue the practice of splicing so it is the only active jack.

The noise is about the same although a bit more stable and is holding between 10 and 11 I also hit 12. So it is at least slightly improved. The connection doesn't feel so brittle. I don't know if it's fixed entirely so we'll see.
