Hi, I am a new Centurylink customer and am having similar problems installing a tp-link td-w8950nd. On the username/password do I use the centurylink.net email I set up or my randomly generated account ID & password? I have tried both & the authentication fails either way.
In the quick set up I get an error 020 to check my WAN parameters/settings & network connection. I am able to ping the tp-link from my computer & I have it set to a dynamic ip address.
When I try to set it up using the web based setup wizard, I get the following failures.
Test ATM OAM F5 end to end ping
Test authentication with ISP
Test assigned IP address
Ping default gateway

Any advise on what I am doing wrong would be greatly appreciated!

I also looked through the modem's logs, and every 30 seconds there is a log entry that simply says "Call Failed". (Doesn't seem very informative to me, but maybe someone else will know what it means.)

Out of curiosity, does CenturyLink require the full account email address as the user name? SBC was so busy merging, and maintaining legacy domains that now, as AT&T, they have eleven different domains, such that {%User%}@ameritech.net, {%User%}@pacbell.net, and {%User%}@bellsouth.net are all viable names, and need the domain part to differentiate accounts.

Of course, if CenturyLink is forcing all subscribers to use a single email domain, that is probably a moot issue.

Nope, ours is just an account name with no '@' or domain name. The same is the case for several other CTL customers in town whose DSL I've helped get set up.

Since we're able to get the DSL light, and our SNR and line attenuation look good (at least according to the sticky), would I be correct to conclude that we can narrow this down to either an issue where the ISP didn't get our account set up correctly, or a problem with the modem/configuration?

If that's the case, would it make sense for me to go over to a friend's house in town (who has CenturyLink DSL of this speed working) and try to connect to my DSL account from there, using their known-to-be-working modem? (Should that work, assuming the ISP has my account set up correctly? And inversely, would its not working suggest that the ISP does not have my account set up correctly?)

Have you contacted CTL support about this? What have you asked them, and what were there responses?

The Call Failed message indicates that the modem is not able to establish a valid PPPOE session. Have you tried adding the domain name to your user id? Did they switch you to DHCP?

If you're in an oldtime Sprint / Embarq area - they well could have you on DHCP , especially with the 10M service. I'm positive my area is using DHCP, but I use my Embarq 660 in bridge mode - not router. I also have an old Sprint 645 modem that also works in bridge mode . I'm only on 3M service, though.

I talked to Centurylink tech support, and they have switched over to the dynamic IP option (not PPPoE) in some regions. Using the dynamic setting, I am now passing every test except the end to end ping & I still cannot access the Internet. I am about to just rent a modem. Blah.

Rent it for long enough to get the settings correct.
