RB411U and Sierra Wireless 250U

I am trying to get a connection with Sprint using 3G and/or 4G.

So far I am trying to follow this guide… http://wiki.mikrotik.com/wiki/Option_Globetrotter_HSDPA_USB_Modem

Could someone help me with the correct settings to get this to connect to Sprint?

Have you checked all suggestions from,
http://wiki.mikrotik.com/wiki/Option_Globetrotter_HSDPA_USB_Modem#Typical_things_to_check

  • different port;
  • async,debug logs could provide with additional information about the problem.

Thanks for the help but I am currently at my knowledge limitation with this. Any pointers would be nice or if I could pay a consultant I would be open to that.

you haven’t posted any actual problem description. please tell us what the logs say, as sergejs already asked.

These run similar to the Sprint 598U… they will work with the same settings Etc…

You MAY need to play with the USB channels, but as I remember they work on the same ones as the 598..

Search the foruns for my prev posts on the Sptint series of USB modems and you will find what you need…

Trust me.. There is a LOT of work allready done on the Sprint series of cards..

Heve fun !!!

  1. RouterOS → v5.22
  2. 411U board
  3. I can’t make Sprint 598 3G usb data card to work when 411U boots up. It will only
    work when I disconnect and reconnect and than it recognize my usb device but I can’t
    make this card to work in cold boot. I have increase my boot-delay time to 9s but no
    difference. Appreciate any support. Thanks
