• Issues enabling WiFi


    I am trying to enable WiFi from my built-in PCI:

    02:00.0 Network controller: Intel Corporation Dual Band Wireless-AC 3165 Plus Bluetooth (rev 99) 

    I downloaded my drivers from here: https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html
    Extracted and copied to /lib/firmware and rebooted. Doesn’t work.

    I tried taking my interface up:

    ip link set wlp2s0 up

    Didn’t report any issue and didn’t help either.

    And I tried connecting a USB adapter, but it didn’t work either, no notification that something is connected and a green light on the USB device, didn’t work.

    I know this must be very common issue for newbies but I couldn’t find any solution that works for me. Any suggestion?

  • @ahassoun try that:

    modprobe -r iwlmvm iwlwifi

    get info about driver options:

    modinfo -p iwlwifi

    try loading without 11n support:

    modprobe iwlwifi 11n_disable=1

    check this:

    systool -v -m iwlwifi

    if it works, make it permanent:

    sudo nano /etc/modprobe.d/iwlwifi.conf
    and add this inside this new file:

    options iwlwifi 11n_disable=1
    options iwlwifi swcrypto=1

    Save with [Ctrl+X]

  • there are known issues with getting firmware for this device, may you need to check the firmware …

    May also try the LTS Kernel instead of the current one!

  • I am in LTS now. I repeated steps for modeprob and nothing changes.

    How about the external USB wifi adapter? Could it work? Or my hardware won’t like Antergos?

  • Solved :) by editing modprobe.d/blacklist.conf

    And added

    blacklist ideapad_laptop

    I now can see available wifi networks. Although I am still unable to access web but could be issue with my network. Will troubleshoot this later but at least I can see the networks now

  • Thats nice to see you get it working! where do you find the hint?

  • This is what got my Kali to work! (Same laptop, I came from Kali)

    I didn’t try it on first time because you suggested this command which I assumed are similar.

    modprobe iwlwifi 11n_disable=1
