    Can't get wifi (AX200NGW) to work in Ubuntu 16 kernel 4.15, Acer Predator

    Hi guys, hope someone can give me some help on this. I need to keep using this distro and same kernel for the main purpose of the laptop, but need wifi to work.
    I've trying backporting iwlwifi but no luck.
    Here's some output

    Code:
    ~$ dmesg | grep iwl

    Re: Can't get wifi (AX200NGW) to work in Ubuntu 16 kernel 4.15, Acer Predator

    Despite all the interesting messages, it seems that an acceptable firmware file is found and loaded and a wireless interface is created:

    iwlwifi 0000:40:00.0 wlp64s0: renamed from wlan0
    Does it scan and see networks?

    Code:
    nmcli device wifi list
    Is the switch set to enable the wireless radio?

    Code:
    rfkill list all
    Any other interesting clues?

    Re: Can't get wifi (AX200NGW) to work in Ubuntu 16 kernel 4.15, Acer Predator

    Thanks for help guys

    Does it scan and see networks?

    Code:

    nmcli device wifi list
    Yes, it does show networks after the things I've tried before, but the system hangs when I click connect.

    Code:
    nmcli device wifi list

    Is the switch set to enable the wireless radio?

    Code:
    rfkill list all
    this one looks allright

    Code:
     rfkill list all

    Any other interesting clues?

    Code:
    dmesg | grep wlp
    yes, maybe here we have some clues

    Code:
     dmesg | grep wlp

    I suggest that you rename one or both of these instances; perhaps 2degrees5 and 2degrees2.4. Then try to connect to one or the other and tell us if it still hangs.

    Re: Can't get wifi (AX200NGW) to work in Ubuntu 16 kernel 4.15, Acer Predator

    I renamed one of the files in this directory.

    Code:
    /etc/NetworkManager/system-connections$ ls -al
    total 36
    drwxr-xr-x 2 root root 4096 Mar 28 19:41 .
    drwxr-xr-x 8 root root 4096 Mar 19 07:04 ..
    -rw------- 1 root root  434 Mar 28 19:40 2degrees2
    -rw------- 1 root root  459 Mar 28 19:41 2degrees2.JL13H0
    -rw------- 1 root root  475 Mar 27 01:00 2degrees Broadband - 46E2.14D4H0
    -rw------- 1 root root  475 Mar 27 00:27 2degrees Broadband - 46E2.2CU5H0
    -rw------- 1 root root  475 Mar 27 00:31 2degrees Broadband - 46E2.6XETH0
    -rw------- 1 root root  475 Mar 27 00:48 2degrees Broadband - 46E2.MLFWH0
    -rw------- 1 root root  475 Mar 28 12:34 2degrees Broadband - 46E2.Y1GMH0
    then edited the file and changed the id field. Rebooted, tried to connect and hanged again.
    I suggest that you rename one or both of these instances; perhaps 2degrees5 and 2degrees2.4. Then try to connect to one or the other and tell us if it still hangs.
    I don't know if I'm doing this right.
    Thanks!

    I don't know if I'm doing this right.
    I'm sorry if I didn't explain the process carefully.

    I am suggesting that you go into the administrative pages of the router and rename the name that is broadcast, like this:



    Your routers setup or administration pages will no doubt look different, but I hope this illustrates the process.

    I did it, tried to connect and the system hanged. Now can't boot.
    Tried recovery mode and it hanged when was booting the full mode.
    Please, I appreciate your help.

    I did it, tried to connect and the system hanged. Now can't boot.
    Tried recovery mode and it hanged when was booting the full mode.
    Please, I appreciate your help.
    Are you able to boot at all in any mode?

    If so, you may get an idea of the trouble if you check the message log:
    Code:
    cat /var/log/syslog | grep -i error
    cat /var/log/syslog | grep etwork

    I can't even boot in recovery now. At some point it was booting and the GUI hanged when trying to automatically connect to the network at startup. But now I'm only getting to this point (pls forgive the pic):
