RPi WiFi issues. Power_save ?

[MochaBrowser]

Hi,

Just set up a headless Rpi 4 with WiFi only. Or tried at least.

The Pi boots, I see it appearing from the router and successfully getting an IP.

But I cannot connect via ssh :

$this->bbcode_second_pass_code('', '$ ssh alarm@192.168.1.72
ssh: connect to host 192.168.1.72 port 22: No route to host
')
and the Pi disconnects after a minute or so and disappears from the router's list of connected devices.

On the debian I used to do :

$this->bbcode_second_pass_code('', '
$ sudoedit /etc/rc.local
------------------------
[...]
iw dev wlan0 set power_save off
')
Is that still a problem with Arch linux as well ? I've just never been able to get this Pi to work reliably with WiFi...

Thanks very much !

I've managed to plug in a screen. When I reboot, wifi works for a few seconds, then I get
$this->bbcode_second_pass_code('', '
ieee80211 phy0: brcmf_p2p_send_action_frame: Unknown Frame: category 0xa, action 0x8
')
and network becomes unreachable. The screen is flooded with
$this->bbcode_second_pass_code('', '
brcmfmac: cfg80211_set_channel: set chanspec 0x**** fail, reason -52
')
relevant logs :
