@Kauãã your dummy get s an other connection than your main character and sometimes this means the rooting to the server is different which results in a different ping. Resetting the router might work if i remember correctly
Different port is used, it's always random, different routing or traffic shaping is done by some ISPs. Restarting client can help (or setting fixed dummy_port), restarting router doesn't help. It's not your router deciding the problematic route
