[SOLVED] wpa_supplicant keeps disonnecting

I'm on the fresh arch install.

I'm using NetworkManager. The problem is after 15-20 mins after boot my wifi-connection drops and I cannot reconnect again. No systemctl restarts help.

It must be something with my wpa_supplicant since during disconnnect,
journalctl -u wpa_supplicant --since crash

Re: [SOLVED] wpa_supplicant keeps disonnecting

Do you use dhcp or a static IP assignment? Please post your dhcpcd, or similar, log if you do. Does dmesg show any errors?

Re: [SOLVED] wpa_supplicant keeps disonnecting

I'm using NM internal dhcp and dmesg doesn't show anything suspicious.

My lspci:

02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88W8897 [AVASTAR] 802.11ac Wireless

Re: [SOLVED] wpa_supplicant keeps disonnecting

I tried also netctl with dhcpd and wpa_supplicant same effect - after 10minutes of working disconnects.

systemctl status netctl@myconnection:

Apr 26 17:54:58 arch dhcpcd[675]: wlp2s0: carrier lost
Apr 26 17:54:58 arch dhcpcd[682]: ps_bpf_recvbpf: Network is down

Apr 26 17:54:58 arch dhcpcd[675]: wlp2s0: deleting default route via 192.168.0.1
Apr 26 17:54:58 arch dhcpcd[675]: wlp2s0: removing interface
Apr 26 17:54:58 arch dhcpcd[675]: dhcpcd exited

Pls help. I'm getting out of ideas.

Re: [SOLVED] wpa_supplicant keeps disonnecting

Have you tried disabling  power  management for your wifi driver?
After the last system update I am facing a similar issue. I am unable to connect via network manager but wpa_supplicant is working for me without any issue.

Re: [SOLVED] wpa_supplicant keeps disonnecting

Wow, you guys are great. The problem was clearly with power saving on for wifi.

For references what solved the problem was adding `wifi-powersave-off.conf` to /etc/NetworkManager/conf.d/:

[connection]
wifi.powersave = 2

once again thanks guys!
