Misurazione Efficienza Rete

[techsupportupgrade]

Vi chiedo un aiuto ho una rete così configurata:

Modem router>>>wifi<<<router in wireless client mode===computer linux
192.168.1.1
vorrei chiederVi esiste un tool per minurare la velocità e ampiezza di banda di ciascuna tratta della rete con linux visto che non riesco ad accedere a nessun dispositivo via telnet grazie.

Sei sicuro che il telnet sia abilitato su quei dispositivi?

sul modem router sì c'è
sul router non so mi sembra proprio no.
