Lets start i ll explain here to complete ur re-configring your SB-5100, SB-4100 or SB-3100 cable modems

Theory of cable modem working

All the cable modems when it boots up it will search for an "Image file" where in all configuration like your upload speed limit and download speed limit is defined. This "Image file" is stored in ISP TFTP's server. Modem will be pre-configured with the ISP TFTP's server IP -address and the Image file name to be downloaded. When the modem boots up it query TFTP's server and download Image file from TFTP's server according to this this our speed limits will be set.

Our Mission
Obtain this required image file from ISP`s TFTP's server, reconfigure it according to our need and force our modem to download this file from our Computer rather than downloading it from our ISP`s TFTP server.

Steps to accomplish

1). Obtain cable modems MAC address
2). Obtain your ISP TFTP's server IP- address
3). obtain name and path of the "configuration file" or Image file stored in the ISP TFTP's server.
4). Download Image file from ISP TFTP's server.
5). Decrypt the Image file which you downloaded from ISP TFTP's server
6). Modify the Image file
7). Encrypt the modified Image file
Cool. Modify ur computer's TCP's config same as ISP TFTP.s server (i.e. IP -address same as ISP TFTP's server)
9). Hostt TFTP's server in your computer
10). Put Image file in the base directory of your TFTP
11). Restart your modem
12). Changer your PC's IP back as given by ISP
13). lol its done surf with a great speed now
