this modem will work on Charter Internet . I buy this product to replace my old Linksys befcmu10 v2 modem since that thing be still run on DOCSIS 1.0 . I just want to make sure that it be not the DOCSIS that be cause the modem to crap out once in the a while . the modem would keep restart after the isp do a firmware update . just a note this do not mean it will import the transfer rate also I be not use Gigabit feature from the wan connection .
