Re: Centurylink frequent disconnects.

Log in to the modem and check the line stats. SNR and Attenuation numbers are what you are looking for. Then connect the modem to the test jack at the NID and check the numbers again. If there is a significant difference in the numbers, you have an inside wiring issue. If not, you could have a line issue further upstream. It is also possible that you are just too far away for the speed you are set at and it may need to be lowered.

I don't have a phone cord long enough to stretch to the NID, I'll look and see if I can buy a 50' cord this weekend.

Thanks for the help.

Your modem is showing sync at 5888 kbps down and 576 kbps up. Those figures are lower than they should be for 6/768 service.

Your modem is showing down SNR at 10.6 dB and down attenuation at 42.9 dB. Neither figure by itself is horrible, though the 10.6 dB is somewhat marginal; but together is odd. At 9,156 feet, my old AT&T ADSL connection was 11.0 dB SNR and 51.0 dB attenuation.

I think your attenuation should support 6.0 M service, but something is drastically wrong to hold your SNR that low. The test at the NID will determine if the problem is premises (inside) wiring (higher SNR at the NID) or plant (outside) wiring (same SNR as at the jack).
