I've been running for several days two machines connected to the same router via WiFi, running ros Melodic, and I also have the same problem:

I can roslaunch from the "master" to the slave perfectly using the Hostname, no errors, all topics OK, can communicate without any kind of issue. But, after some time, when the slave recieves a DHCP request to renew or a KeepAlive, the master loses connection to the slave, even though the IP and Hostname of the slave does not change.

I don't know what else to do. Everything works fine for some time, but suddenly the master cannot communicate anymore with the slave, but they can still ping eachother and so on.

Is there any configuration that I'm missing?
