stations cant communicate with each other in mininet-wifi #444

Closed Rahi63 closed 2 years ago

Rahi63 commented 2 years ago

Hello, I have Opendaylight controller and mininet-wifi on Ubuntu 20. when I run simple mininet, all my hosts can ping each other, and the network works properly. but when I run mininet-wifi the stations can't ping each other. Also, I can run some examples like mesh.py without any problem. could you please help me?

Is network manager running? Are stations associated with APs? If you confirm associations, this means that you have a problem with the control plane.

Thank you for your answer, but I don't think the stations are associated with APs.

I stopped the network manager with: sudo systemctl stop network-manager but in the end, the problem remains

Any issues with sudo mn --wifi -v debug?

Rahi63 commented 2 years ago

I have run this command before but unfortunately, I could not understand anything from it to fix the problem

I could solve the problem by resetting the network manager. Thank you for your help
