I am using a comcast cable modem that is about 5 years old. My QOS is very erratic. sometimes it's 96% sometimes 45%. The jitter ranges for 2.2 to 7or 8. Do you think a new cable modem would help? I did but a new dlink dr655 router and it works fine.

There may be other problems that are giving you those kinds of results. Could you post the signal levels at the modem?

If you are renting that cable modem from Comcast, take it to their local office and tell them you want a newer one. You don't have to explain why. That's the only upside to renting IMHO.

I can tell you that I went to a house last week (comcast user) with back speeds, high pings, etc. Multiple power cycles didn't help. I had them buy the new Motorola 6120 modem and their speeds and service skyrocketed. It's an expensive modem but it's future proof as it has DOCSIS 3.0. Highly recommend.

Glad to hear your good experience with the Motorola SB6120 modem. I also have an older modem that I am renting from Comcast. The rent was $3/month. Then without warning they increased it to $5/month. So I ordered the SB6120 today from Amazon for $94.10 with free shipping. I did a lot of research and it comes highly recommended.

No problem. I need to get one myself but my speeds are so good, I don't want to screw up a good thing. :) I have now installed 2 of these, I did another one with good results. Same position as you on the $5 as well all hate giving comcast anymore money. ;)
