[Help] Devices Cannot Ping Within or Across Networks in Mininet-WiFi

[Christian Agyekum]

Dear Mr. Ramon 

I am currently working on a project using Mininet-WiFi and I have encountered some connectivity issues that I have not been able to resolve. I would greatly appreciate any insights or suggestions from the community.

1. Intra-Network Ping Failure

   When I attempt to ping a station from its associated access point within the same network, I receive the following output:

mininet-wifi> ap3 ping sta31  

PING 192.168.3.2 (192.168.3.2) 56(84) bytes of data.  

From 10.0.0.3 icmp_seq=1 Destination Host Unreachable  

It appears the access point is unable to reach the station, even though they are configured to be in the same subnet.

2. Inter-Network Ping Failure

   Additionally, when I try to ping a station located in a different network from another station, I get the following message

mininet-wifi> sta15 ping sta55  

ping: connect: Network is unreachable  

This suggests a routing or configuration issue preventing communication between subnets.

I have attached the Python script that I used to create the network topology and configure the hosts and access points.

Thank you for your time and assistance.

Please review how OVS works, as this topic has already been thoroughly
discussed on this mailing list.

You have some action points assigned that haven’t been started yet.
Additionally, this may involve an L2/L3 issue, so please make sure to
explore all available alternatives.
