Can't ssh over wifi [solved]


I can ssh to my Raspi over LAN but not over wifi. While pinging works, ssh connections are refused or never answered.

boris@iti27:~$ ping PING ( 56(84) bytes of data. 64 bytes from icmp_seq=1 ttl=64 time=5.89 ms 64 bytes from icmp_seq=2 ttl=64 time=5.69 ms 64 bytes from icmp_seq=3 ttl=64 time=5.47 ms

boris@iti27:~$ ssh root@ root@'s password: Permission denied, please try again. root@'s password:
In this case, the terminal freezes and doesn’t react to Ctrl-C:

boris@iti27:~$ ssh volumio@
volumio@'s password: 

I use the password volumio in both cases.

If you have updated to v2.144 via the UI, please reflash your sd card with the latest image.

I flashed the card some days ago with 2.041. I’ve ssen that there’s 2.114 now, I’ll try that.

Yep, reflashing the card with the latest build cured this for me.

Just flashed 2.114. Didn’t help, same problem as before. It freezes or tells me “Permission denied”.

I noticed that I can ssh over wifi if and only if the LAN cable is attached.

I also noticed that ifconfig eth0 down doesn’t deactivate eth0. Instead, the connection becomes unresponsive for a few seconds and then eth0 is up again.

The solution is to add

IPQoS cs0 cs0

to /etc/ssh/sshd_conf.

For the sake of clarity for others reading this post, could you just confirm (or otherwise) that you have a RPi3 and you are using the onboard wifi … from what I have Googled, it would appear to be a RPi3 wifi chipset problem??

Yes, I have a RPi 3 and I use the onboard wifi.
