the zoom5350 be a excellent product and be easy to set up . the only adjustment I have to make be at the zoom website in the configuration manager -lrb- I simply unchecked one of the box as be suggest -rrb- . this change improve both download & upload speed . I replace a older DOCSIS 2.0 modem that work fine , but have slower download speed in the 5-8 mbp range . this zoom be DOCSIS 3.0 which allow I to receive the full 30 mbp that my cable provider supplies . I be a average computer user that prefer to web browse without wait .
