Cable Modem Compatibility Issue with XFINITY
I Received a letter from Comcast that my CMD 31t cable modem needed to be replaced to take advantage of greater speeds. I checked on line and their list of acceptable DOCIS 3.0 modems did not include...
Hi,
If you dont mind, can you please PM me the copy of the letter (Please remove your private information).
CMD31T is on comcast list but tops off at 105 Mbps on comcast's mydeviceinfo info page.
SOme of the ISPs now require 8x4 modems to take advantage of 150 Mbps tiers.
technically CMD31T can support 130-145 Mbps TCP in real world ( 160 Mbps PHY speed) but it is dificult for operators to deliver that kind of speed over 4 channels.
what kind of subscription do you have?
when did you get your CMD31T?
