Hack ur ISP + MODEM n get highspeeds…as much as u want
Hack Your Modem and Increase YourDownload Speed
Hack Your Modem and Increase YourDownload Speed from 64Kbps to any Speed You Wish
Most of us will be feeling that thesurfing speed which is allocated by our ISP is not enough. People with 64Kbpswill think 128Kbps will be cool speed. People with 128Kbps will think 256Kbpswill 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 youto 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 toexplain you as best as I can to accomplish re-configuring your SB5100, SB4100or SB3100 cable modem
Theory of cable modem working
All the cable modems when it boots upit will search for an “Image file” where in all configuration like your uploadspeed limit and download speed limit is defined. This “Image file” is stored inISP`s TFTP server. Modem will be pre-configured with the ISP`s TFTP server IPaddress and the Image file name to be downloaded. When the modem boots up itquery TFTP server and download Image file from [TFTP] [server] according tothis this our speed limits will be set.
Our Mission
Get this Image file from ISP`s TFTPserver, reconfigure it according to our need and force our modem to downloadthis file from our Computer rather than downloading it from our ISP`s TFTPserver.
1). Get cable [modems] MAC-Addreaa
You can either look at the back of themodem to get this MAC Address or you can logon to your Cable modem with yourWeb Browser hxxp://192.168.100.1/ . This is internal HTML pages stored withinyour DOCsis cable modem (SB5100, SB4100 and SB3100) that gives you even morevital information on configuration. Unless it is turned off by your ISP. Thisfeature might be totally turned off by your ISP.
2). Get your [ISP] TFTP server IPaddress
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
http://sourceforge.net/projects/docsis
Using the above tools you will get theinformation of your ISP`s TFTP server IP and the name of your “Image file”stored in that TFTP server
All your vital information is storedin 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 yoursthroughout in the doc)
IP-to-If-index.10.$$$.$$$.$$$ = 2
Suggestion: You can do this step bysniffing the modem i.e. “192.168.100.1″ when modem boots up. I never tried thismethod. Try your luck.
3) Download Image file from ISP`s TFTPserver.
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 yourISP`s TFTP server.
4). Decrypt the Image file which youdownloaded from ISP`s TFTP server
For all you can use the DOCsis toolCode:
Code:
http://sourceforge.net/projects/docsis
to decode
5). Modify the Image file
Change your computer’s TCPconfiguration same as ISP`s TFTP server (i.e. IP address same as ISP`s TFTPserver)
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 itto as following values
Configure your TPC’s TCP settings asbelow
IP: 194.*.*.90 (replace with the ISP’sTFTP server)
Netmask: 255.255.255.0
Gateway: 192.168.100.1 (replace withyour cable modem’s IP address)
Note: Gateway should be 192.168.100.1then 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 hostTFTP server in your computer
You can download TFTP server from:Code:
Code:
ftp://ftp.ida.net/pub/wireless/tftpd32.exe
. Put Image file in the basedirectory of your TFTP
Start TFTPD32 server. Go to Settingsand set the Security to None. Increase the timeout to 20secs and the MaxRetransmit to 6. Choose to translate UNIX filenames. Make sure it’s basedirectory point to where the isrr.bin is (i.e. the image file which youmodified). If you need to replicate a directory pathname along with the imagefile, then make a directory from root that corresponds to the image filepathname.
Restart your modem, and AS SOON as theSEND light goes solid, you should see a receive on your TFTP server i.e. yourPC
9). [Restart] your [modem]
10). Changer your PC’s IP back asgiven by ISP
11). OOPS Done. Start surfing withyour new speed
Note: This speed will remain sameuntil you restart your cable modem. So each time you reboot your modem you have to follow the steps 7 to 11 .
Googd Luck
