[SOLVED] NetworkManager failing to connect to wifi networks

Up until yesterday NetworkManager had been working fine on my network. Then yesterday it began dropping internet access (but still reporting that it was connected to the network) and eventually dropping the connection entirely. This has been happening whenever I attempt to connect to the network.

Now, nm will not even connect to the network, it appears to attempt authentication but fails. Ethernet however, works perfectly.

Here are some of my logs:
journalctl
dmesg
lspci

Is ip-config available on your system?

No it is not, I also can't find it via pacman/aur.

ip-config isn't a program/package (on linux at least). This message just means that DHCP is timing out.

This thread may be relevant: https://bbs.archlinux.org/viewtopic.php?id=146261. You could also try a different dhcp client.

Re: [SOLVED] NetworkManager failing to connect to wifi networks

Thanks for the advice, I have solved it.

Turns out this laptop (the one that wasn't working) is the only device on the network that uses the 2.4GHz band of the router, rather than the 5GHz/ethernet that the rest of the network is on. The 2.4GHz band was made more unreliable with a new firmware update to the router and the channel the signal was on was congested. After moving the channel, the signal and packet loss has greatly improved.
