TLP and wpa_supplicant issues

After the upgrade to 4.11.2-1-ARCH last night I realized that wpa_supplicant can not connect to my router anymore. Nothing has changed at all, and in the logs I've seen a lot of

For me it looked like a power management issue, so I disabled the TLP service - and that solved the problem.

Now my configuration for TLP is:

# WiFi power saving mode: on=enable, off=disable; not supported by all adapters.
WIFI_PWR_ON_AC=off
WIFI_PWR_ON_BAT=off

So looks like it shouldn't be an issue, but apparently there's sort of interference with TLP and wpa_supplicant

Please advice.

Thanks!

Re: TLP and wpa_supplicant issues

I realized that wpa_supplicant was started by systemd-networkd and NetworkManager, so that caused conflicts.

Hence removing the dependency on NetworkManager from TLP systemd unit solved the problem.
