CM1200 suddenly dropping on Comcast

I contacted ISP, and the lady on the other end said she was looking at the modem right now and she sees nothing wrong on her end. She then said she sent several packets to it and it returned all it fine.

 I told her that NetGear support said it had to be between the modem and where the line connects. She said I can do anything else with customer owned equipment. I asked if I could send her the logs and screen captures and she said no, but you could send them to a tech specialist and they would read it as a first come first serve basis. She said I could have a tech come out and check the line, but they would charge me $49.95 if they found nothing on their end. I said, "oh no... I am not paying that again for some guy to come into my house and hook up his equipment to my line and check my router and modem and say, well I am not seeing a problem", He said..."but yes your speed is definitely cut in half of what you should be getting...don't tell them I said this because I could get fired, but it looks like they are throttling you." He left, problem was never resolved because they said it was my equipment. I told her go ahead and set me up with that  $4.95 a month fee so if I do have a tech come out again, I don't get charged another $50 for nothing.

Ended up purchasing the NG CM1200 to replace the Arris. That was done in end of June of this year. Everything has been fine until the last few days.

I since the call this am, guess what... No dropped Internet!!! But I am still monitoring the logs.

BTW, I gave the Arris to my Aunt... It is still working perfectly for her.
