I'm on the 3Mbps plan, so it appears that I am getting what I'm paying for. All the Comcast plans here are limited to a max upload speed of 256Kbps. Unfortunately, I can't test call quality now because I'm waiting for my number to port and I didn't request a temporary number. I'm tring to resolve any possible issues before I switch over to VoIP. I guess from here I'll just have to wait until the port is complete and see how things work out. With the jitter problem resolved and speed apparently OK, I'll take your advice and not worry about the QOS number until/if it really is a problem.Aveamantium wrote:Not sure about how important it is to get the newest Firmware but yours is running a pretty old version. QOS at the VoIP site is measuring how consistent your speed is. In other words if it fluxuates then you'll get a bad score. I occasionally get a bad score but it has never caused me voice issues. Jitter is a much bigger problem to solve and it looks like you did that. If you call quality is good don't worry about Qos. As for speeds is the 2.9 down and 0.24 up what you're paying for? If not, and you're not getting help through comcast go here http://www.dslreports.com/forum/comcastdirect and post your problem, "ComcastSteve" will take care of you. If you have the wrong speeds then your modem has the wrong config file (by the way you can't check your config file with a SB6120, only Comcast will know what you have unless it is listed in your logs).
Thanks for all your help. Oh, and how would I go about updating the firmware for the new modem?
