rp4 fresh install - cannot connect to any wlan

Apr 25, 2021 12 Replies

Hi,



today i install a fresh raspbian (debain buster) on my new rpi4. Kable Network is working well. Wlan settings are set - but it does not connect to any wlan.



"iwlist wlan0 scan" find my wlans as expected (and working with other wlan devices)



cat /etc/wpa_supplicant/wpa_supplicant.conf



ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 country=US



network={ ssid="[my ssid]" psk="[my pw]" key_mgmt=WPA-PSK }



Does anybody has a idea for this?

i forgot:

cat /etc/network/interfaces.d/wlan0

auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

A longshot, but is your SSID set for a channel (e.g. 13) that isn't licenced in USA?

What does iwconfig say? You seem to have ebverything where it should be

My Raspi doesn't work if I enable WPA3 in my Router.

Hi,

the AP is also set to US.

Yes, everything looks good, but no connection. As i say: my ssid will be listed in iwlist wlan0 scan

~:iwconfig lo no wireless extensions.

eth0 no wireless extensions.

hmm... i didn't know, that WPA3 is already on the market... My AP is set to WPA2 auth. What i dont understand: it is an new raspi, fresh debian without "anything" else... and not connecting...

For all who had a similar problem: In my case: the dhcpd was not running - why the hell this on a fresh installed system?

Ok, after starting dhcpd -i got a connect and a ip Adresse.

Jan

So how did the cable network connect?

Actually I take that back, surely you need dhcpcd, ie the client demon as opposed to the server demon, dhcpd.

yeah post systemd the names changed.

I should try Devuan on the rpi4, just to see if it works...

Devuan Beowulf works on a pi4, but it can be fun and games finding a copy :o
