  • How to check that my WWAN M.2 module is working.

    From Ankit Burman@21:1/5 to All on Tue Dec 6 23:05:52 2022
    Hi I tried interfacing my M.2 WWAN module but it is not detecting in my Linux OS. how do we verify whether it is present or not ?

    Use lsusb and lspci.

    lsusb for an M.2 module will do nothing. And lspci I suspect will do
    nothing either, it is not the PCI bus.

    I tried on a computer here, and the m.2 disk is not detected that way.

    Best hope is google: "how detect M.2 modules in Linux?"

    It depends on the device. M.2 can provide PCIe (lspci detects also
    PCIe and AGP), SATA or USB.

    I would expect the majority of WWAN modules are USB, even in M.2 form
    factor. lsusb should show it.

    I tried on a computer here, and the m.2 disk is not detected that way.

    M.2 storage can be either PCIe (would show in lspci as an NVMe device) or
    SATA (would not, but would show at boot in dmesg).

    I've never used one. A quick search leads to https://www.kernel.org/doc/html/latest/networking/device_drivers/wwan/index.html

    Figure out which kernel module is needed and try loading it with modprobe.
    See if that shows anything in the journal.

    True, my module is USB and can be detected by lsusb.

    fdisk and lspci both show my m2 ssd. It comes up as /dev/nvme0n1

    The WWAN module is for a wireless wide area network device, not a storage device.

    WWAN is similar to a wireless internet device but instead of connecting to a router it connects to a cellular network like cell phones do.

    The WWAN module is for a wireless wide area network device, not a
    storage device.

    True, and therefore it can't use SATA via M.2, but it can use PCIe or
    USB.

    Also, to be usable, it will not only require support in the kernel, but
    also configuration frome userspace applications where you might need to
    set things like network operator and access point names. Example of some
    WWAN documentation:
