...we were told that our current PVR and modem would stop working and that we must update to BlueCurve, Since then we found out 1-the equipment would have still worked (others we know still use them) 2-BlueCurve has no local storage - (maybe we were lied to so that we'd have to buy cloud storage ?) Our TV stream is often choppy, frequently blanks out, and we must reset the equipment at least once a week. User's recommendation: stay away unless you need wireless for many tvs etc,,,
