    3G/4G dongle with TM-AC1900



      I am trying to use my 3G/4G tmobile dongle with this router.  I use it as my backup connection.  The dongle works fine when I plug it into a pc and I am able to connect to the internet fine.  The sim is a tmobile data sim only.


      The dongle is model ZTE MF691 Rocket 3G 4G - which is supported by asus




      The device tries to connect and comes back with


      "Unable to connect to the Internet, please re-enter the information, or double-check your account data with your ISP."


      It doesn't matter which APN I try - epc.tmobile.com (no user/pass/dial) or the old internet3.voicestream.com ones.  It never connects.




      Thank you

          I'm assuming you followed the instructions on pages 40 & 41?


          Have you looked at the logs to see if there's a specific error message?

            did you do the setup on the router's page under USB application?

              Yes i read those (and did the setup under USB, also tried the connection wizard) - the only thing that appears related in the log is

              I notice that my exact model is not in the list on the device - i have it set to "Auto".  The website shows as supported.  This is an old USB stick so i figured the firmware must be new enough

                Does Tmobile read these forums? or am i posting in the wrong place?

                  Yes they do but with the volume of threads it takes a while
