• No longer able to see any wifi networks - Gnome

    I’m not sure if this is because a recent update, but I have not changed any internal settings on my dilapidated laptop.

    [[email protected] yeep]# wifi-menu
    Scanning for networks... failed
    No networks found

    Any thoughts on what I can test to find the issue?

    Thank you!

    Ok, you have a Realtek 8723ae, which should work out of the box.

    What’s the output of rfkill? It should look something like this:

    [[email protected] ~]$ rfkill
    ID TYPE      DEVICE      SOFT      HARD
     0 wlan      phy0   unblocked unblocked
     1 bluetooth hci0   unblocked unblocked

    If it looks more like this:

    [[email protected] ~]$ rfkill
    ID TYPE      DEVICE      SOFT      HARD
     0 wlan      phy0     blocked unblocked
     1 bluetooth hci0   unblocked unblocked

    then you need to unblock your wireless network. The command is “rfkill unblock all”

    Failing that, have you tried the solutions listed in the Arch wiki?

  • @TaraF Here is the rfkill output:

    [[email protected] ~]$ rfkill
    ID TYPE      DEVICE                 SOFT      HARD
     0 bluetooth Toshiba Bluetooth unblocked unblocked
     1 bluetooth hci0              unblocked unblocked
     2 wlan      phy0              unblocked unblocked

    I have looked at the document you sent, but I have no errors related to powersave. Wifi was working great until a recent update. I guess I am of the opinion right now that something has changed.

    You are correct, out of the box, my wifi worked flawlessly.

    Thank you for any ideas.

  • I see that the wlp2s0 state is down:

  • @YeeP
    Maybe you have accidentally disabled wifi? Is there a physical switch? Or are the wireless network connections still set up OK? Wifi password’s OK?

    If that doesn’t help, you could try the LTS kernel.

  • @manuel Nope no physical switch on this laptop for wifi. Just an internal setup. I used to have it setup as a dual boot, and with that I could test both sides. Alas, I eliminated windows from this machine recently and made it a pure linux one. I could boot up with a live antergos disc to see if wifi works there.

    Can I change Kernels without reinstalling Antergos?

  • @YeeP
    In my case the networkmanager 1.14.6 stopped connect, I downgraded to 1.14.5 then now 1.14.7 is available which works without any problem. Could it be same problem maybe?

  • @YeeP

    Can I change Kernels without reinstalling Antergos?

    Yes. The LTS kernel can be installed with command

    sudo pacman -S linux-lts linux-lts-headers     # headers is optional

    and after reboot, select LTS kernel from the additional options of the grub menu.

    BTW, downgrading may help, but that’s just a temporary workaround until the real problem is resolved.

  • @Edwin-Foss
    Wow, that really got me excited, but unfortunately I have 1.14.7 already. :(

    I will try falling back to 1.14.5 as a test.

    That was a bust, still no wifi networks show in the network manager. The 26th on those updates sure sounds familiar though as far as when I first noticed I didn’t have any networks available.

  • @YeeP

    Add the following to file /etc/modprobe.d/rtl8723ae.conf:

    options rtl8723ae fwlps=0

    More at https://wiki.archlinux.org/index.php/Wireless_network_configuration#rtl8723ae/rtl8723be

  • @manuel said in No longer able to see any wifi networks - Gnome:

    options rtl8723ae fwlps=0

    [[email protected] ~]$ ls /etc/modprobe.d/
    i915.conf  nvdimm-security.conf
    [[email protected] ~]$ sudo vim /etc/modprobe.d/rtl8723ae.conf
    [sudo] password for yeep: 
    [[email protected] ~]$ cat /etc/modprobe.d/rtl8723ae.conf
    options rtl8723ae fwlps=0

    Rebooting just in case…

    EDIT: No luck there either. I will download a live copy of antergos at work today and burn it to a flash drive just to test and see if I have wifi with an “unchanged” copy. Thanks to everyone for trying to help. I did scan the journalctl for a bit, even grepped it for ‘wlp2s0’, no clues yet.

  • @YeeP
    But did you try the LTS kernel?

  • @manuel No, not yet. I just kind of feel like this is some package upgrade that got me. I am trying to figure out what the package in question is.

    Here is a screen shot from the live antergos usb. Connected to my network no problem. So at least I know this is not a hardware issue.


    I will try the kernel change.

  • @YeeP
    It may well be a kernel update issue, that’s why testing with another kernel might help.

  • @manuel I installed the LTS kernel and went into the options menu while in Grub, I did not see any specifications as to which kernel would be loaded. Do I need to manually add an additional option in the grub config file to boot into the LTS kernel?

  • @manuel LTS kernel did not fix the problem, however, the “fallback” selection in grub does have working wifi.

  • @YeeP
    That fallback thing sounds like reinstalling linux might help:

    sudo pacman -S linux
