    Hi, I want to use my RAP-3WN with HUAWEI K5150 (Vodafone branded) LTE modem as a uplink. But I'm not successful in provision RAP with correct modem config.

    Modem works flawlessly with my Linux host. I have to use usb_switchmode to switch it to ethernet mode. Than there is new interface where it is possible to get IP address with DHCP and connect to the net.

    But no luck with RAP:

    show ap debug usb ap-name rap-01

    USB Information
    ---------------
    Parameter         Value
    ---------         -----
    Manufacturer       HUAWEI
    Product            K5150
    Serial Number      
    Driver             cdc_ether
    Vendor ID          12d1
    Product ID         1575
    USB Modem State    Standby

    Following line is used for modeswitch in RAP provisioning:

    -v 0x12d1 -p 0x1f16 -V 0x12d1 -P 0x1575 -M 55534243123456780002000080000a11062000000000000100000000000000

    I use same VIDs/PIDs and message with usb_modeswitch at my Linux host.

    Does anybody have idea how to solve this ? Is network adapter style USB modem compatible with rap ?

     

    Thanks.

    I managed to hack in the RAP with TTL-USB serial converter. It is necessary to set console password in the controller:

    ap system-profile rap-ap-system-profile

    than login to console and press Esc ^k to get full access (enable doesn't work).
    There are some log in /tmp. lte.log looks promising, but there is only:

    Setting up data connection...
    Modem mode not available - need to repair this

    Does it mean that this modem is not supported?
