waver168, it was a pretty straightforward call to AT&T to get a replacement router sent. No complaining needed. I just told them the recent history of having to reboot the gateway each morning. I think if you call and tell them that, you'll have success in getting a replacement one sent to you.
Also, I would call on a weekend or at odd hours if you can help it; avoid calling in the evenings. I think you will have less of a wait time. Seems like weekday evenings are the busiest times.
Good luck! I'll send feedback on how my the new gateway helps me.
esteeze, I called up techsupport this morning, the guy claims 6db is the floor for noise margin(what?!), but he ran the line test and did say something is not right and is sending a guy over to see where the noise is coming from. Not sure if I'll get a new RG....
6db is the min, if its lower than 6db than you will experience problems if its over 6db it is considered within specs(Not saying that its right but testing will show passing)
think of it as a pipe a pipe that is only 6in can only let so much signal in but a pipe that is 20in has a lot of room for signal the greater the nosie margin the better your signal so a low noise margin could be too high a speed for how far your distance is from central office or vrad or could be interference from other signals or could be bad wiring or outside drop wire etc..
