    I’m having a hard time getting my Intel Dual Band Wireless-AC 7260 to work with my fresh installation of Ubuntu 16.04.3. There are similar questions to this, but all of the ones that I could find are dated. Currently, its not even showing any networks to connect to.

    Here is some output that other posts (e.g. this one) led me to believe would be useful for helping solve this problem:

    The information on this Intel site leads me to believe that the iwlwifi-7260-14.ucode should be making this work, but its not.

    Accepted AnswerAnswer

    From our discussion in chat, and seeing nothing else incorrect, it appears that in connecting the PCIe mini-to-PCIe adapter, the antenna wire was either not connected or wiggled loose. You opened the computer and connected the antenna firmly and the wireless is working!
