Hello,
How can I change the ports on bitcomet to try for better connections
Simply specify a different listen port in your preferences, then be sure to block the old port on your firewall(s) and unblock the new one.
Changing ports won’t make a difference in your connections. Any one port is as good as any other. It only matters if you’re trying to do two things on one port, though most systems won’t allow you to do that.
