said by Jim721:My question is will [previously activated/provisioned modems] stay working or will it drop off the account at some time in the near future as comcasts updates there system?
From what other posters have said here, like NetFixer
, it appears your older modems will stay associated with your account, unless you ask to have them removed.
Some posters with old DOCSIS 2.0 still listed have said that they were getting calls about upgrading, even though they have been using a newer D3 modem for a while.
My old SB6121 is still listed on my account page, with a data usage monitor shown for it, so that should I ever reconnect it, the data meter would start to accumulate under that one.
