I only get a link local address, so I can't connect to the internet. All other devices connected to the network work, and the WiFi card works in Arch Linux and Windows.
Edit: I solved it by enabling the RT2800PCI option in the kernel configuration.

0x9fff00,

[ 496.155660] wlp3s0f0: deauthenticating from <router mac address> by local choice (Reason: 3=DEAUTH_LEAVING) |
That shows that its working but you asked it to stop. That's what Reason: 3 means.
The usual cause of this is more that one network controller trying to use wpa_supplicant at the same time.
This is supported by the cycling shown in dmesg.
How do you start your WiFi?
There it a lot of debug junk in dmesg. Some debug options interfere with normal device operation.
They are intended for debugging the code, not individual connection issues. Turn this off.

That's because I pressed ctrl+C to run another command. After that I ran wpa_supplicant again with the -B option.
Here is the output from ping that shows that it's not working:
| Code: | # ping -c 4 8.8.8.8

Like this:
| Code: | # wpa_supplicant -B -Dnl80211,wext -i wlp3s0f0 -c <(wpa_passphrase <ssid> <password>)
# dhcpcd wlp3s0f0 |
I've tried the ncurses versions of NetworkManager and Wicd too, but they didn't work either.

What do you mean? How do I do that? |
