Today I'll share my experience and the steps I took to resolve connectivity issues with my home server after setting up virtual machines using VirtualBox. These issues involved intermittent drops in remote connection and even temporary unavailability of SSH on the host machine. After researching various forums, it appeared that disabling power management on the WiFi card of the Linux Mint host machine could be the solution.
To address this problem,I followed the steps in this StackOverflow answer while connected to the host machine through SSH.
That's it! By disabling power management, you should have addressed the connectivity issues on your machine. Remember to restart the NetworkManager to apply the changes.
