There are many ways to improve your device settings - but they make small differences. Key is a sound card and wired network (which you already say you have).
But by far the biggest impact is where you and the other players are with respect to the Jamulus server you use. I am in Scotland and my server is in London - hosted in AWS EC2. That's about 600km each way. But I manage a ping time of about 18mS and overall delay of about 30mS. Anything above about 50mS we found increasingly difficult and not enjoyable. I have achieved these figures with Windows 10 or Ubuntu PCs. Wired Android tablet and smartphones are slightly worse (no external sound card).
In Jamulus everyone connects to a central server, sends their audio there, then a mix of everyone's audio (and yours) is sent back to each person. So no matter how many people you have, the bandwidth to/from the server is the same. As a result we don't find any difference when more people join.
Key is each person's connection to the server. Are they all getting good overall delay (as described above)? If not, consider trying a different public server, or placing a private server somewhere else. It's easy to install a private server, host it on your own PC at home, and test it - you will get a great connection of course, but how about everyone else connecting to you? Do you have sufficient bandwidth at home? How is their overall delay? Sometimes using my home server does actually work better for everyone than the AWS-hosted ones.
AWS EC2 free tier is a great place for private servers - free for a year, great connection to the Internet, so great to test. Is there an AWS region that is close to your musicians? If you're located in Germany, for example, there has been quite a lot of discussion about alternatives to AWS from more local hosting providers. A good place to start is the Jamulus discussion forum and wiki... Jamulus ‒ Play music online. With friends. For free. If you haven't visited for a while, there continues to be new information added all the time.
