Unable to activate wifi

Unfortuantely I'm unable to post the exact output messages as I can't get my laptop on wired LAN at the moment.

After I installed Arch a while back wifi and wired worked fine. I've been on wired for a few months. Laptop is fully updated with the latest updates. Since my battery was dead the laptop as on wired and power and never moved. I ordered a new battery and detached the power and wired LAN, to find out wifi wasn't working anymore.

After some troubleshooting, I found it was hard- and softblocked. Rfkill list showed that. My hardware button toggles through all possible combinations, so after a few toggles, I end up with nothing hard- or softblocked (all devices, asus-wlan, bluetooth, wired, and psy0 all are unblocked).

When I type

ip link show

It shows all network adapters, including wlp3s0. The links are down obviously.

When I now type

ip link set wlp3s0 up

I get no output, it just returns the prompt.

In dmesg I get

[date/time] IPv6: ADDRCONF (NETDEV_UP): wlp3s0: link is not ready

When I try:

nmcli con up mywifi

it says:

Error: Connection activation failed: No suitable device found for this connection.

There is nothing new in dmesg.

In addition, in journalctl after rfkill unblock wifi and restarting NetworkManager, I get

systemd[1]: starting load/save RF kill switch status
systemd[1]: started load/save RF kill switch status
NetworkManager: wifi now enabled by radio killswitch
kernel: IPv6: wlp3s0 link is not ready

I'm at a loss. I have no idea why it doesn't want to activate wifi. According to the search results I found, after the blocks have been released using rfkill unblock all or toggling using the hardware switch, it should be able to activate wifi.

When I reboot the machine, the blocks are back and I'm back to square one.

Thanks for the help!

Re: Unable to activate wifi

Try to disable networkmanager, (rf)unblock all, activate wifi manually using wpa_passphrase (check wiki). This helps to pinpoint if it's an unblocking problem or a daemon/networkmanager problem.

Have you tried disabling IPv6?

Re: Unable to activate wifi

This may not directly help with your problem, but if you need to show your exact messages you could always output the messages using:

 foo > bar.txt 

Copy this to a usb and plug in to your desktop.

Or are you using your phone/tablet (kudos typing all that out if you are!)?  You could still transfer the file with a usb cable.

This worked, thanks!

What would be the problem with NetworkManager? It kept saying the interface was disabled.
