 Hack Your Modem and Increase Your Download Speed from 64Kbps to any Speed You Wish
Most of us will be feeling that the surfing speed which is allocated by our ISP is not enough. Guys having 64Kbps thinks 128Kbps will be nice speed. Guys with 128Kbps thinks 256Kbps will be nice and there is no stop for our greediness
 This tutorial will teach you how to increase your 64Kbps link to 512Kbps or what ever speed you like.
 It is very much possible to do this. With a bit of luck if your Cable Internet Service Provider are very uneducated on how this very new technology works and leave some key loopholes open for you to grab vital information on how to accomplish this task. But this tutorial will no guarantee you 100% success.
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). Get cable modem MAC-Address 

You can either look at the back of the modem to get this MAC Address or you can logon to your Cable modem with your Web Browser 192.168.100.1/ . This is internal HTML pages stored within your DOCsis cable modem (SB5100, SB4100 and SB3100) that gives you even more vital information on configuration. Unless it is turned off by your ISP. This feature might be totally turned off by your ISP.

2). Get your [ISP] TFTP server IP address 

a) There's a program called QUERY.EXE from Weird Solutions which is a BOOTP packet request program that will tell you everything you need to know, without all these extra steps. It will display the Image Filename, TFTP server address, which is really all you need to get started. To use this BOOTP QUERY tool, you need the MAC address of your cable modem or Beginners can use DOCSIS Diagnosis utility 
docsis

Using the above tools you will get the information of your ISP`s TFTP server IP and the name of your "Image file" stored in that TFTP server 

All your vital information is stored in this file, One of which is the MaxRateDown 2621440; MaxRateUp 393216;. (This was my ISP settings. Which you can see is similar to what speed I was getting. 40KB/s up and 250 KB/s down) 

Among these, the one we need are: 

Configuration [TFTP] [Server] = 194.*.*..90 (replace this with yours throughout in the doc) 

Configuration filename = isrr.bin (replace this with yours throughout in the doc) 

And 

IP fragments created = 0 

IP address.10.$$$.$$$.$$$ = 10.$$$.$$$.$$$ 

IP address.192.168.100.1 = 192.168.100.1 (the IP address of the cable modem, (replace this with yours throughout in the doc) 

IP-to-If-index.10.$$$.$$$.$$$ = 2 


Suggestion: You can do this step by sniffing the modem i.e. "192.168.100.1" when modem boots up. I never tried this method. Try your luck.

3) Download Image file from ISP`s TFTP server. 


For doing this got to your command prompt and use below commands with out quotes and bracket. 

"C:\tftp -i GET " 

Okay now you got Image file from your ISP`s TFTP server. 


4). Decrypt the Image file which you downloaded from ISP`s TFTP server 
For all you can use the DOCsis tool 



5). Modify the Image file 

Change your computer's TCP configuration same as ISP`s TFTP server (i.e. IP address same as ISP`s TFTP server) 
Go to my network place and right click ->properties

Select your LAN Card right click ->property->Internet Protocol (TCP-IP) double click on it and change it to as following values 

Configure your TPC's TCP settings as below 

IP: 194.*.*.90 (replace with the ISP's TFTP server) 

Netmask: 255.255.255.0 

Gateway: 192.168.100.1 (replace with your cable modem's IP address) 

Note: Gateway should be 192.168.100.1 then only your modem can communicate with computer. 

6). Encrypt the modified Image file (Save it using Docsis)

7). Host TFTP server in your computer

Download TFTP Server software
and host TFTP server in your computer

You can download TFTP server from:
MEGAUPLOAD - The leading online storage and file delivery service8). Put Image file in the base directory of your TFTPStart TFTPD32 server. Go to Settings and set the Security to None. Increase the timeout to 20secs and the Max Retransmit to 6. Choose to translate UNIX filenames. Make sure it's base directory point to where the isrr.bin is (i.e. the image file which you modified). If you need to replicate a directory pathname along with the image file, then make a directory from root that corresponds to the image file pathname.


Restart your modem, and AS SOON as the SEND light goes solid, you should see a receive on your TFTP server i.e. your PC


9). Restart your modem.

10). Changer your PC's IP back as given by ISP.

11). OOPS Done. Start surfing with your new speed.
