DM111psp and Airport extreme problems..

Need Help-

After breaking my Actiontec dsl modem, as of 07/13/2013 I have a new DSL modem DM111psp. When the ethernet cable is connected directly to my computer, I have internet. When I bridge the modem to my airport extreme, I get a green light on the front of the airport, but no internet access. This is not a computer issue as the internet worked with bridging the Actiontec dsl modem to the AE before I broke it. At first, I thought it was a security setting that did not match in the computer. For example, if router was set to WPA personal and the computer was set to WEP, there might be a problem, but this was not the case. I even turned off security.

According to Centurylink, my ISP, they informed me that I need to setup the modem as PPPOA. Infact I tried PPPOE and get no internet. Internet only works with PPPOA. Internet setting in the AE is set to ETHERNET and to automatically detect settings.

I even reset my AE and rebooted. Still only get green light on AE, but no internet. All lights on DM111psp are green also. The problem seems to be the signal the DM111psp is sending to the AE.

In the modem settings or AE settings, there does not appear to be any setting for RFC

  • have you tired power cycling both?
    modem 1st then AE after 3mins?
  • Just called my ISP and they informed my that my dsl is ATM. Don't know if this matters....

    Absolutly tried that. Powered everything off including computer. Powered everything back on, one at a time. First the AE until green light. Then DM111psp until green lights, then computer. I then powered down everything again and restarted in different order.... modem, then AE, then computer.
  • Usually PPPoA can not be authenticated at router so prior to changing the DSL unit other one was modem/gateway. Authentication was done at DSL unit

    With DM111p unit plug computer directly and setup authentication first and check Internet if that works AE should be plugin to dm111p with Ethernet option to get private IP from the dm111p

    I am kind of a amature when it comes to computers and trying to follow you...
    When I first setup the DM111psp, it was connected directly to my computer and internet worked.

    I then plugged the DM111psp into the AE. After a few minutes of adjusting password setting in AE, the light went from amber to green. (green is good :) ) Inside the menu settings of the AE, where the option to set AE to Ethernet is, the AE auto populated the modem's ip address. I am at work now, so not at that computer, but I seem to recall the ip addy being 192.168.0.1 AE has been set to Ethernet.
  • ok... that worked. However I do have a iconcern
    In the modem (dm111psp) where the bridging protocol can be selected.... (PPPoA, PPPoE, or RFC2684) Why do I NOT have a option for RFC2684? Just PPPoA and PPPoE in the drop down.

    The reason I am worried is that I also have an Airport express being used as a wireless print server. I called Apple tech support to find out why this wireless print server would not connect to the AE and I was told by Apple tech support that when the router is in bridge mode (not Ethernet) that it shuts down wireless capability.

    Any way around this?
    I mean.... is this setup you described is the only way a Netgear DM111psp and a airport extreme can be joined together? or is there another dSL modem product that will work instead of the DM111psp. I was looking at the Netgear N600 w/ DSL modem, but the majority of reviews are bad and I don't think it would be as good a router as the Airport extreme. (reviews on Amazon)

    Read again

    You use PPPoA authentication on DM11P

    Not sure why you are changing to the setting to bridge on AE. You should seutp on DHCP for internet port
