I have a 509 with MTU set to 1500 as well. Note MTU is not a "speed", as you say, but rather stands for "maximum transfer unit", which, as the name might suggest, is the maximum size of a transferred block of data (roughly equivalent to a single packet size limitation). Playing with your MTU is usually not necessary. # ifconfig ep0 ep0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 <..
