I just recently buy this modem to update my 5 year old zoom that seem to be have issue turn out it be router that need replace , so I have a Asus 56 on the way . however , I be keep this because it be blaze fast , I notice a huge jump in internet speed almost instantly . I be go to give this four star because it say the light be suppose to be Easy to understand and I be a tech guy and I still do not understand they ... and there be not even a mention of they in the manual ... good job ubee . anyways if a Ubee guy come and comment on my post tell I how to interpret the light you 'll get a 20 % boost and reclaim you 5 star rating .
