Cable Modem Uncapping

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. People with 64Kbps will think 128Kbps will be cool speed. People with 128Kbps will think 256Kbps will be cool and so on

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.

Okay here we go. I'm going to try to explain you as best as I can to accomplish re-configuring your SB5100, SB4100 or SB3100 cable modem

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`s TFTP server. Modem will be pre-configured with the ISP`s TFTP server IP address and the Image file name to be downloaded. When the modem boots up it query TFTP server and download Image file from TFTP server according to this this our speed limits will be set.

Our Mission

Get this Image file from ISP`s TFTP 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 modems MAC address
2). Get your ISPs TFTP server IP address
3). Get name and path of the "configuration file" or Image file stored in the ISP`s TFTP server.
4). Download Image file from ISP`s TFTP server.
5). Decrypt the Image file which you downloaded from ISP`s TFTP server
6). Modify the Image file
7). Encrypt the modified Image file
8). Change your computer's TCP configuration same as ISP`s TFTP server (i.e. IP address same as ISP`s TFTP server)
9). Host TFTP 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). OOPS Done. Start surfing with your new speed


1). Get cable modems 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 http://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 ISPs TFTP server IP address
3). Get name and path of the "configuration file" or Image file stored in the ISP`s TFTP server.

For getting this vital information you have to do an SNMP walk over your modem. For doing this you can use any one of the tools below

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
You can download this from:
http://www.weird-solutions.com/_bin/bootpq.exe

Or

Experts can use Solarwinds SNMP program
You can download this from:
http://www3.solarwinds.net/downloads/Solar...-EE-V7-Eval.exe

Or

c) Beginners can use DOCSIS Diagnosis utility
You can download this from: http://homepage.ntlworld.com/robin.d.h.wal...ag/docsdiag.zip

Or

d) Beginners can use SNMPWALK Tool
You can download this from:

http://www.bradford-sw.com/board/board.cgi...download&gul=13

use command "snmpwalk 192.168.100.1 public"

NOTE: Use modem's IP address as "192.168.100.1" (SB5100, SB4100 and SB3100) when it asked to provide by any of the above tools. SNMP community is "Public"

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.xxx.xxx.xxx = 10.xxx.xxx.xxx
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.xxx.xxx.xxx = 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.


4). 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.


5). Decrypt the Image file which you downloaded from ISP`s TFTP server
6). Modify the Image file
7). Encrypt the modified Image file

Use docsis tool which you can download from

http://sourceforge.net/projects/docsis

using this program you can decrypt image file change the upload speed and download speed ,save it and encrypt back. Rename this newly created file same as your original image file.


8). 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.


9). Host TFTP server in your computer
10). Put Image file in the base directory of your TFTP
11). Restart your modem

Download TFTP Server software and host TFTP server in your computer
You can download TFTP server from:
ftp://ftp.ida.net/pub/wireless/tftpd32.exe

Start 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


12). Changer your PC's IP back as given by ISP
13). OOPS Done. Start surfing with your new speed

Now you change your TCP settings of your PC back to normal as given by ISP. (I.e. Put your original IP address and gateway)

Oops you hacked your modem. Test out by downloading some files using DAP (Download accelerator plus)

Note: This speed will remain same until you restart your cable modem. So each time you reboot your modem you have to follow the steps 8,9,10,11 and 12


Enjoy

For Adsense Newbie

Before you apply to AdSense

Getting started with AdSense is easy, but when reviewing the applications we get, we've noticed a few common pitfalls. To help make sure your application is approved the first time around, ask yourself the following questions below before submitting.

Do I have what I need to apply?

• Website: To display Google ads, you need administrative access to the site you submit for AdSense in order to place our JavaScript ad code on your site. Adding the Google code to your site's source code will enable you to show ads, search boxes, and referral units on your pages.
  
  If you don't have a website of your own, that doesn't mean you can't participate in AdSense. We offer a couple of options to help you easily create your own site.
  
  First, there's Blogger, a free tool for setting up and publishing your own blog online. With its easy-to-use and customizable templates, you can create an account and start blogging right away. You can also set up AdSense ads easily through your Blogger account.
  
  If you prefer more flexibility and control, then our web page tool, Page Creator, may be more suitable. Signing up for a Page Creator account is free as well -- all you need is a Gmail account. The best part is that you don't have to download any software or hire a designer. Once you've created your Page Creator site, you can begin displaying Google ads in minutes.
  
  
• Valid payee name: Payments will be made out to the name on your account, so make sure to include your full and valid name, or that of your business, rather than just initials. If banks won't accept the name you enter in the 'Payee Name' field, neither will we.
  
  
• Valid address: We want to make sure your hard-earned money reaches you, so please also provide a complete valid address where you can receive mail. If you live in a country or territory that doesn't have a standard format for addresses, please be sure that your application includes as much information as a mailman would need to find your residence.

Does my website meet all the necessary requirements?

• Valid URL: If you manage an entire website, give us the URL of your home page. If you manage a blog or other account within a larger website, you should provide the URL of the specific page that you manage and not the URL of the entire hosting website. Don't forget to double check your URL for typos!
  
  
• Fully launched website: Since we won't be able to review websites that are not fully launched or built, please ensure that your site is live and functioning at the time you submit your application.
  
  
• Unique content: We want visitors to sites in the AdSense network to have a good experience, so please publish content that's interesting and unique. Avoid using "doorway" pages created just for search engines, or other cookie cutter approaches such as affiliate programs with little or no original content. If you're participating in an affiliate program, give people a reason to visit your site first.
  
  
• Supported language: We're constantly working to provide targeted, relevant ads in more languages. However, until then, we can only approve your application if the majority of your website is in one of our supported languages.
  
  
• Pay-To Sites: If your site participates in programs that compensate people to perform activities that drive traffic to you, we can't approve your application. Some examples of these "pay-to" programs are sites that encourage users "to click" or "to surf" or "to read email." In addition, you shouldn't encourage others to join these programs in the content, links, or third-party ads on your site.
  

We also encourage you to read our program policies in detail for further insight on how to create a successful application. Now that you have all the necessary information, now's a good time to apply.
