Reason not to buy used nor refurb. What was wrong when you used their modem again?
What is your tested download and upload speeds now using www.speedtest.net? Just give us the down and up numbers. I don't need all the other stuff. I gave a procedure previously to try your IP address swap like you used to. Did you see it?
So is your Ooma calling working ok now?
What is left problem wise? The Docsis 1 modem thing?
Have you tried the speed test at several different times of day? I am using the Motorola SB6120 from Amazon I have had for months (docsis 3 with docsis 2 and I am docsis2) with Brighthouse Max Turbo. I just got 16.38 down and 1.9 up while not making a call with the Ooma, on speedtest.net, but 23.5 and 1.9 on the Brighthouse test. I'm wondering if speedtest.net is bogging down. I can get 25 down and 1.9 up (my max is 2) sometimes during the night. I'm thinking cable systems are getting saturated like people used to warn about. I'm looking at trying U-verse.
Anyway, try your speed tests during late night and early morning while not making a call to see if you can get close to what your cable system is saying you should get, and let us know what concerns are left now.
Point your browser to http://192.168.100.1 (cable modem status page) and looking for the upstream + downstream power and signal to noise ratio. I post mine as a samplecjw7 wrote:Comcast wouldn't do anything about the docsis 2.0 running in 1.1 mode problem.
Some folk here has more knowledge on this stuffs and sure will help your to find the problem and/or how to deal with Comcast.RF Parameters

If you pay monthly modem lease, you can demand a new modem replacement without any reason. I guess maybe your modem is the problem. Some poster had confirm that their problme solved with new cable modem.

Your SNR is little bit low, but I don't know much about this stuffs. Maybe Murphy will chime in.murphy wrote:The downstream signal power should be between -10 and +10 dBmV. (Some say between -15 and +15 but I feel that is pushing your luck)
The SNR should be 35 or more.
The upstream power level should be less than 55 dBmV.
At least you have some thing concrete to complain to Comcast, and have them come out and check the signal.
Then recheck the signal parameters at 192.168.100.1
This will determine the signal quality of the incoming signal independent of the wiring in your house.
