modems account

 i was wondering if i purchased the net gear 2050v modem do you think when Comcast goes to dosis 4.0 that net gear  modem will be capable of doing that?

i had one more question is their a monthly fee for having another modem on the account (it will be a customer owned modem)

Thanks in advance

Another good question, @ralphj43! We do not charge for customer owned modems at this time. Also, please refrain from posting any personally identifiable information such as your full name when using our forums as it is considered a public platform, and we want to protect your account details! Thanks for reaching out. Let us know what other questions you have, and our Digital Care Team remains here to help however we can!

Great question ralphj43! We keep our authorized and approved devices list updated in real time. As something comes approved it would pop right into the list, unfortunately, we do not have updates on the when side of the question. But I included a link here below to our authorized devices' section of our website. You can easily monitor this to keep an eye for when that specific unit comes up approved.

@ralphj43  The Docsis version 4.0 hasn't been updated to our system to be able to determine what modems will be compatible with this new service type. You're more than welcome to use the link my colleague shared periodically after we announce that Docsis 4.0 will be available in your area.
