retiredqwest posted : If you only have the 1 jack then a filter is unnecessary, especially since you don't have a landline dialtone.

At the NID did the modem lose sync at all? If it still drops at the NID then you will need a tech visit.

Another thing you can do since there is no dialtone on the DSL line. Is plug in an old analog phone into the phone jack on the modem and when there is a problem listen to the line and see if you hear any noise or static.

Mikesalz posted : I will try this. The only thing is I only have 1 jack that has connection in my house. Does that even matter?

Do you consider the DSL a active phone line if I dont have a "phone line" with Centurylink and I only pay for internet? I ask this because I dont use a filter or wondering if I am less likely to get noise on my line.

retiredqwest posted : Your levels are:

SNR Down = 20/21 Up = 9/14
Attenuation Down = 17 Up = 7

Your attenuation numbers mean you are VERY close to the DSLAM.

The down SNR 20 is good, but the up SNR 9/14 is a problem. Something is affecting the SNR up by 5db.

You should try connecting the modem directly to the NID/SNI/Protector or whatever one wants to call it and see if those numbers are still the same. Not knowing what your residence is, this may be a problem. At least try to prove its not in your wiring.

Unless a tech can isolate a noise problem on your line. About the only other thing would be a bad port in the DSLAM.

Intermittent trouble is the biggest pain in the rear to find.

Here's a good reference for the above readings:

Noise Margin (AKA Signal to Noise Margin or Signal to Noise Ratio)Relative strength of the DSL signal to Noise ratio. The higher the number the better for this measurement. In some instances interleaving can help raise the noise margin to an acceptable level. 6dB or below is bad and will experience no synch or intermittent synch problems7dB-10dB is fair but does not leave much room for variances in conditions11dB-20dB is good with little or no synch problems20dB-28dB is excellent29dB or above is outstanding Line AttenuationMeasure of how much the signal has degraded between the DSLAM and the modem. This is largely a function of the distance from the exchange. The lower the dB the better for this measurement. 20dB and below is outstanding20dB-30dB is excellent30dB-40dB is very good40dB-50dB is good50dB-60dB is poor and may experience connectivity issues60dB or above is bad and will experience connectivity issues

It contains the Line Attenuation , SNR, etc.

Mikesalz posted : Our modem keeps lossing connection to "ISP" (says connecting in yellow through Modem Config) and every other time looses connection to both Qwest Broadband and ISP (both are red and say not connected in Config). This has been happening for a month or two. I must reboot the router for it to work again, its getting ridiculous!

About my modem/router PK5000Z
First has WPS off just enabled last night after reading something about it being the problem on this site. Want to leave it on and see if it effects.

Also had a tech out they looked at their server and re-did the port. They said it leaves me with two possible options for the cause. Something about authentication with my user name and the server and my overall modem which I got "new" from Qwest in June.

Ill attach some screen shots with working correctly and the issue I am getting. Let me know what you think. Thank you
