I have have this little speed demon now for a little over 10 day . it work great with absolutely no flaw . I just go with Comcast in Northern ca , after be with att for the last 12 year . with att I have drop internet at least 3 time a day . Comcast and new cable modem do not believe in drop internet . go from under 5 mb with att to 26 plus mb with Comcast . after switch over to Ooma and drop att , I now pay less than I pay for the att with phone and internet charge . Life be good . while it be true that no instruction or warranty card come with the Ubee , the hook up be pretty much impossible to mess up since all the cable will only fit into they respective orifice . have not have one drop internet connection with the Ubee or Comcast . Good-Bye att . its be fun all these year . I would consider come back if you would get better product and service than my current isp . it be call COMPETITION ... and you lose !
