Just wondering if anyone else here is into modem hacking? Once i found out how simple it was i wanted to kick myself for not getting into it sooner. Now i enjoy 30mbps download speeds for the small cost of basic cable ($15/mo with comcast). So far as i'm aware it also makes me a lot more anonymous on the internets, since my modems mac address isnt linked to any account on record...and if i want to i can even change the mac address.
You're a fucking idiot.
When the CMTS detects your modem, it uses one of two means of determine what user you are: your serial number or your MAC address. Upon connection, a modem ranges, locks on to a downstream and upstream frequency, and then using TFTP, it receives a QoS telling it what speed it is capable of. In the event that the MAC or serial is not registered, the accounting system either denies the range to be completed or the modem and any device behind it receives a private IP address, denying any outside routing.
Effectively, you're a terrible bullshitter.
