No SSH on Wlan0

#1

Hi,

i use the Rock5B several weeks on Ethernet with fixed IP over RDP and SSH.

Now i bought a Wifi Card and i cant access any services (ping,RDP,SSH) over Wifi, but i can see correct IP in my Access Point Status and correct settings in ifconfig.

Hi, Schuppeste

What system do you use? What is the model of your WiFi module? wlan0 does not appear to be getting an IP. wlP2p33s0 xxx Is this the correct device? What is the output of the command ip route?

#3

oh…

System:
Linux rock-5b 5.10.110-31-rockchip-ged1406c748b1 #rockchip SMP Sat Nov 26 04:03:23 UTC 2022 aarch64

Wifi Chipset:
rtl8852be

ip route:
192.168.0.0/24 dev enP4p65s0 proto kernel scope link src 192.168.0.101 metric 100
192.168.0.0/24 dev wlP2p33s0 proto kernel scope link src 192.168.0.113 metric 600

dmesg
[ 17.346697] rtl8852be 0002:21:00.0 wlP2p33s0: renamed from wlan1
[ 27.167687] IPv6: ADDRCONF(NETDEV_CHANGE): wlP2p33s0: link becomes ready

Yes, its the correct device. but not wlan0, its wlan1.

when i disconnect the Ethernet Cable, i cant ping or anything on 192.168.0.113, reboot no change.

The A8 wifi exposes two wlan interfaces, which seems to confuse Linux to no end. wlan0 doesn’t seem to be the default interface and this (maybe) messes up the ssh server. I have the same problem.

#5

Ok, i wait to have to spend more time… in this moment i dont use keyboard and monitor, so i cant Debug myself.

I look next Days, normally i can solve it since 15 Years in Linux…

but nmcli is new for my side. I must read next time.

Thanks.

Confusing…

The System has detect two wlans in Dmesg, Wlan0 and Wlan1 and renamed wlan1 to wlP2p33s0 (maybe P2p whatever) and used it as default connection (Connected to Router like Ethernet via nmcli). i add a route, so only the Browser works, but not ssh.

Now i have installed the xfce “nm-applet” and change the configuration of connected Network to “wlan0” interface.

Then i add a default Route:
sudo route add default gw 192.168.0.1 (IP=Internet gateway Router)

Now, it works. Thanks for Replies.

But you can simple use nmcli:

nmcli dev wifi connect Routername password PASSWORD ifname wlan0

without “ifname”, nmcli use the renamed Device without default Routings.
