    Unhappy "Unclaimed" Network Interface (Likely Firmware Issue)

    I just performed a fresh install of Kali on a Dell laptop and I'm experiencing an issue with the embedded network interface card. It appears as though no firmware is found for this particular device, however I'm having a difficult time even identifying the precise model/version of the network controller itself -- preventing me from obtaining and building the appropriate driver. I'd be grateful if someone could either help me fingerprint the device or fix the issue altogether.

    I've also tried using modprobe to insert the e1000 and e1000e kernel modules without success.

    Below is additional information regarding the laptop, OS version, and relevant hardware-related command output:

    Kali Version: 4.16.0-kali2-amd64
    Laptop Model: Dell e7470

    Code:

    You can see the first one is a wireless, so you can always search for "firmware intel" using apt-cache then install it and reboot.

    The second one, after doing a quick google search of the device ID (8086:093c) turns out to be a wireless device too, Intel Tri-Band Wireless-AC 17265: https://wikidevi.com/wiki/Intel_Tri-...65_(17265NGWG) and there is no driver for it yet.

    e1000 and e1000e are for wired ethernet devices, so that modprobe is useless.

    Keep wikidevi in your bookmarks, it is very handy to identify wireless devices and drivers.

    One last thing, lsusb and lspci rely on a database to display the information. You can update it using update-pciids and update-usbids
