Hack Your Modem and Increase download speed of 64Kbps Until suit your expectationsMost of us will feel that the surfing speed which is allocated by our ISP is not enough.64Kbps with people will think 128Kbps will be cool speed. 128kbps with people will think 256Kbps will be cold and so on
This tutorial will teach you how to increase your 64Kbps link to 512Kbps or what ever speed you want.
It is very possible to do this. With a little luck if your Cable Internet Service Provider are very uneducated on how this new technology is very successful and left some key loopholes open for you to grab vital information on how to accomplish this task. But this tutorial will not guarantee 100% success.
Let us begin. I will try to explain you as best I can do to re-configuring your SB5100, SB4100 or SB3100 cable modem
Theory of cable modem works
All the cable modems when it boots up it will look for an "Image file" where you are all such a configuration upload and download speed limits are speed limits set. This "Image file" stored in ISP `s TFTP server. Modem will be configured with pre-ISP `s TFTP server IP address and name of image file to be downloaded. When the modem boots up it query TFTP server and download Image file from TFTP server according to the speed limits we will set.
Our Mission
This image get a file from ISP `s TFTP server, reconfigure it according to our need and force our modem to download this file from the computer rather than downloading it from ISP` s TFTP server.
Steps to complete
1). USB modem to get the MAC address 2). Your ISP to get the TFTP server IP address 3). Get the 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). Modifying image files 7). Encrypt the modified Image file 8). Changing your computer's TCP configuration same as ISP `s TFTP server (ie IP address same as ISP` s TFTP server) 9). Host TFTP server in your computer 10). Put the image files in a directory of your TFTP base 11). Restart the modem 12). PC IP Changer return as provided by ISP 13). OOPS Done. Start surfing with a new speed
1). USB modem to get the MAC address
You can see the back of the modem to get this MAC Address or you can log on to the Cable modem with a Web Browser hxxp: / / 192.168.100.1 /. This is internal HTML pages are stored DOCSIS cable modem (SB5100, SB4100 and SB3100) that gives you more information about the critical configuration. Unless turned off by your ISP.This feature might be totally turned off by your ISP.
2). Your ISP to get the TFTP server IP address 3). Get the name and path of the "configuration file" or Image file stored in the ISP `s TFTP server.
To obtain this important information you should perform your modem SNMP easy. To do this you can use one of the tools below
a) There is a program called Strange QUERY.EXE of the solution which is a BOOTP packet request program that will tell you everything you need to know, without all these extra steps. Will display the image file, the TFTP server address, all you really need to get started. To use this BOOTP QUERY tool, you need the MAC address of cable modem
Or
Experts can use Solarwinds SNMP program
Or
c) Beginners can use DOCSIS Diagnosis utility
Or
d) Beginners can use the tool snmpwalk
use command "snmpwalk 192.168.100.1 public"
NOTE: Use modem's IP address as "192.168.100.1" (SB5100, SB4100 and SB3100) when asked to by one of the tools above. SNMP community "General"
Using the tools above you will get information from ISP `s TFTP server IP and the name" Image file "stored on the TFTP server All vital information is stored in this file, One of the MaxRateDown 2621440; MaxRateUp 393 216;. (This was my ISP settings. You can see similar to what I gain speed. 40KB / s up and 250 KB / s down)
Among these, what we need is: Configuring the TFTP server = 194 .*.*.. 90 (replace this with yours throughout in the doc) = Isrr.bin configuration file name (replace with yours so far in the doc) And IP fragments created = 0 IP address.10.xxx.xxx.xxx = 10.xxx.xxx.xxx Address.192.168.100.1 IP = 192.168.100.1 (the IP address of cable modem, (replace this with yours throughout in the doc) IP-to-If-index.10.xxx.xxx.xxx = 2
Tip: You can do this step by sniffing the modem ie "192.168.100.1" when modem boots up. I've never tried this method. Try luck.
4). Download Image file from ISP `s TFTP server.
To do this you can use the command prompt and the command below with the quotation marks and brackets out.
"C: \ TFTP-i GET"
Okay now you got Image file from ISP `s TFTP server.
5). Decrypt the Image file which you downloaded from ISP `s TFTP server 6). Modifying image files 7). Encrypt the modified Image file
DOCSIS uses a tool that you can download from CODEhttp: / / 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 files.
8). Changing your computer's TCP configuration same as ISP `s TFTP server (ie IP address same as ISP` s TFTP server)
Go to my network place and right click -> properties Select your LAN Card right click -> properties-> Internet Protocol (TCP-IP) double click and change it to values as follows Configuring TPC of the TCP settings as below IP: 194 .*.*. 90 (replace with the TFTP server from the ISP) Netmask: 255.255.255.0 Gateway: 192.168.100.1 (replace with the cable modem IP address)
Note: Gateway should be 192.168.100.1 then only your modem can communicate with the computer.
9). Host TFTP server in your computer 10). Put the image files in a directory of your TFTP base 11). Restart the modem
Download TFTP Server software and host TFTP server in your computer You can download from the TFTP server: CODEftp: / / 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. Chose to translate UNIX filenames.Make sure it's base directory to place isrr.bin is (eg an image file to be changed). If you need to replicate a directory pathname along with the image file, then create a root directory of the related image file pathname.
Restart your modem, and AS SOON as the SEND light goes solid, you'll see a receive on your TFTP server ie your PC
12). PC IP Changer return as provided by ISP 13). OOPS Done. Start surfing with a new speed
Now you change the PC TCP settings back to normal as given by the ISP. (Ie Put your original IP address and gateway)
Oops you hacked your modem. Test by downloading some files using fishing (download accelerator plus)
Note: This speed will remain the same until you restart your cable modem. So every time you reboot the modem, you must follow the steps 8,9,10,11 and 12
This tutorial will teach you how to increase your 64Kbps link to 512Kbps or what ever speed you want.
