I must have hear the entire 4 Seasons by Vivaldi . the help agent be rude and unhelpful . he even hang up on I . this modem have be nothing but trouble from the day we get it . we Internet speed slow by 30-50 % . and the problem with own you own modem be that the modem people will always blame the internet provider for any problem and the internet provider will blame the modem maker , and you , the customer be stick in the middle with no recourse . not even a friendly voice from the Zoom company to acknowledge how frustrated you might be . Stay away from this company .  zoom 5350 Cable modem\/router with Docsis 3.0 speed
