no issue with this modem . setup be quick and easy . call WOW and give they the information they need ... then be up and run . compact size fit nicely on the desk . also I pick up just a bit of speed . prior to connect the modem , I check connection speed and be at about 15.75 download and 0.6 upload . with this modem I be now at about 16.25 down and 0.75 up . I also notice on the speed test website that the connection be `` cleaner '' than with the old modem ... i.e once it hit its maximum speed it would stick there without much fluctuation . I buy the modem so that I do not have to pay the $ 5\/month to rent WOW 's modem . the bit of add speed I get be just a bonus . I have have this for a few week so I can not comment on long term quality . but at this point , no issue and I be happy with it .
