  • 1.  Aruba USB LTE modem + 605h accesspoint

    Posted Dec 16, 2024 03:33 AM

    Greetings,

    I've bought an Aruba USB LTE modem and an 605h accesspoint with the intent to use these on sites that I can't get fiber (or doesn't need fiber).

    I've managed to get it to work with the 605h as a remote accesspoint in my lab but only under the condition that I start the accesspoint with the cable and modem connected.

    If I then disconnect the cable it will switch over the USB modem correctly and continue working as intended.

    This behaviour won't however work out on site where I don't have any other way of connection other than the USB modem.

    Is the USB modem only intended as a fallback ?

    Can it not be used as a primary method ?

    You've gone through the provisioning process?

    That's the kind of documentaion I've been looking for :)

    I did a quick new provisioning profile based on the third example but now it won't provsion at all :D

    I belive this is the universes way of telling me to go home and do more tests tomorrow ;)

    Well, a day of testing things out have not made me much wiser.

    I managed to create a provisioning profile where I'm able to provision the accesspoint while connected via cable and i can then switches over to the USB LTE modem when I disconnect the cable.

    However I am still unable to provision/start the accesspoint using only the USB LTE modem for reasons unknown.

    I based the profile from this output:

    You'll want to set the link priority so that the cellular connection is preferred.  Lower (closer to zero) number is higher priority.  Set Cellular to something like 20, Ethernet to 40, and WiFi to 60.

    Link Priority Ethernet                                           0
    Link Priority Cellular                                           0
    Link Priority WiFi                                               0

    I set the priorities according to your suggestion and re-provisioned the accesspoint but unfortunately it still behaves in the same fashion ...

    The previous log was showing the AP reboots because of a lack of IP address, assuming the cellular is working properly on another device, then that's a bit of an odd result.

    I'd recommend opening a case with TAC to troubleshoot at this point.

    I don't have another device to try it on (as this one is on loan from HP via our partner) but as I mentioned it works just fine on that device as long as I don't try too boot the accesspoint with only the USB modem attached and no cable.

    So yes, I'd also file it under the "odd" category.
