Mesh speed + traceroute

[Petri Virkkala]

Hi Javier and Andrey,

thanks for your fast replies!

Connection speed was measured by a simple ssh file transfer between two links. I might be wrong but I remember reading somewhere that there is/was an 1Mbit limit to connection speed. Could it assosiated with the zd1211rw driver we are using?  What else could explain the slow transfer rate?
