I am in search of a router that specifically supports the latest version or is closer to the latest ZeroTier. Currently, I own several GL.iNet routers, but I am encountering problems with slow ZeroTier bandwidth. My current ZeroTier version is 1.8.4, while the latest version is 1.12. I am contemplating whether upgrading to new hardware, along with the latest ZeroTier version, will enhance my speed. Currently, I am only utilizing 13% of my total bandwidth, and I am confident that I can achieve better results with more suitable hardware support.

I'm looking at the following model: RB5009UG+S+IN and L009UiGS-RM and would like to know what is the lastest version of Zerotier that I can install?

The version which comes with ROS is not the latest.
Nothing you can do about that apart from running a container and run zerotier on there.

Current version on the 7.13-stable is 1.10.3

1.10 has some speed improvements from my current 1.8.4 which is a good new. I ordered the RB5009. Thanks.
