How To Hack Cable Modem For Free Internet At Home Or Work

Learn how to hack a cable modem for free internet and never pay for it again. Entitled Knowledge will provide solutions to this and enlighten you on basic aspect. However, while things may appear to be a little technical, you must carefully follow all of the instructions as we will be gradually getting further.

Uncapping cable Modems

If you think your cable modem is too slow, you can uncap it. However, you should be aware that if your service provider discovers this, they will immediately disconnect you and sue you. It doesn't take long for them to notice your efforts. This is considered service theft by the company.

Uncapping a cable modem is often a complicated operation that necessitates using a specific editor to program a docsis configuration file, setting up a tftp server, changing an IP address, and running a dhcp server to deceive the cable modem into downloading the config file from localhost. Despite the fact that some aspects of the process have been automated, there are still a number of snags, but that is about to change.

Onestep is a 30-megabyte program that combines all of the tools needed to perform a cable modem hack into one utility and conceals them behind a point-and-click user interface that allows the user to select his or her cable modem make and model, service provider, and new speed.

The anti-social component of uncapping a cable modem should be considered, as one person consuming too much bandwidth during peak hours could cause bottlenecks for the other users on that node.

Anyway, in this world, there's never enough speed. When 56 kbps dial-up connection was the sole option, customers were frequently terminated by their ISPs for leaving their computers connected 24 hours a day, preventing other users from connecting at all. People demand 10 mbps instead of the 384 kbps that is common with cable modem access now that we have cable modems, which is a reasonably cheap method of connecting to the internet at fast speeds.

Many users have resorted to uncapping their cable modems in order to trade movies and software over the ‘net. The bottom line is if everyone decides to uncap their modems, no one will get any amount of bandwidth and we will all suffer.

How to Uncapp a Cable Modem

Most cable systems are capable of detecting and disabling these modems. The modems usually employ cloned authentication credentials or technician credentials, and the firmware has been hacked to eliminate the account's speed constraints. They may work for a time, but the backend management systems will notice them very quickly. In addition to remote disabling, cable networks have capabilities that allow them to determine where the modem was physically connected, allowing them to prosecute the modem operator for service theft.

Most likely, this unlawful activity will result in a $300 loss while also exposing your address to the cable company's anti-fraud department.

Steps to follow(Docsis compliant Cable Modems)

In most cases, there are two network configurations. The cable modem is immediately linked to the PC. The PC is connected to a NAT router, which has a cable modem connected to its WAN port. Both steps must be followed.

When the cable modem is turned on, it searches its configuration file for a TFTP server IP and a filename. This is the Docsis configuration file, which, among other things, establishes a download/upload bandwidth cap for the modem. The cable modem then connects to the backbone after retrieving the file.

What's the best way to get it uncapped? Simple. We'll download the docsis config file, modify the cap parameters, and then fool the cable modem into thinking our PC is a TFTP server, allowing it to obtain our copy of the docsis file.

There is some effort required for this. First, we must determine the cable modem's TFTP server and file name. We can use the docsisDiag function for this. Among these, the following are the ones we require:

Configuration TFTP Server          = (replace this with yours throughout in the doc)

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


IP fragments created            = 0

IP    =

IP address. =   (the IP address of the cable modem, (replace this with yours throughout in the doc)     = 2

Now from a DOS prompt type:

tftp -i GET isrr.bin

Your ISP has just sent you the docsis setup file. It's now time to make the necessary changes to modify the modem's cap. The Cisco Docsis configuration software in the docsisConfig directory is used to accomplish this. You'll need to update ConfigEdit.bat and follow the instructions inside before executing it. Then run ConfigEdit.bat and open the.bin file you downloaded over TFTP. Go to the "Service Class" tab. Voila’. Increase the Max DS Rate to 7MB (mine won't go any higher). Save.

We'll need to make the cable modem believe we're the ISP and use our own TFTP server to download our version of the file, as shown below.

1. PC Directly Connected to Cable Modem

Configure your PC’s TCP settings for:

IP: (replace with the ISP’s tftp server)


Gateway: with your cable modem’s IP address)

don’t worry about the DNS…

Change your TCP settings to use DHCP again, either manually or via the docsDiag software once it's finished. The speed restriction on your vehicle should now be updated.

2. PC NAT Route ♋ Cable Modem

Set your Router not to use DHCP but to use:

IP: (replace with the ISP’s tftp server)


Gateway: 192.168.100. (replace with your cable modem’s IP address) 

You must now configure the Router so that all traffic is directed to your PC. LinkSys accomplishes this by configuring your PC for DMZ access. It's possible that other routers aren't the same. All that is required is for all external traffic to be forwarded to your PC or for your PC to be visible on the other side of the firewall.

Configure your PC with a static IP address in a range used by your router. Ex. If your router is at then configure your PC for:




Now add an additional IP address to the TCP settings in your PC:

IP: (replace with the ISP’s tftp server)


don’t worry about the DNS…

Because you'll need to instruct your TFTP server to listen to the latter address, this is done.

You shouldn't have to restart your computer. In the tftpd directory, place your updated copy of the isrr.bin (change this with your name). Begin the tftpd32 server. Set the Security to None in the Settings menu. Increase the timeout to 20 seconds and the maximum number of retransmissions to six. Select whether or not to translate Unix filenames. Make sure the isrr.bin file is in the base directory. Click the OK button.

We must now begin populating the routing tables in the devices with our fictitious data. Ping your cable modem, the TFTP IP address, and, if necessary, your router. The cable modem should now be turned off and on. Then, as soon as the config file has been transferred, start pinging your cable modem. You should observe that your tftp server is transferring it your file when the traffic lights blink for the first time. Now, set up DHCP on your router, and then DHCP on your computer. It should now function normally.

How to Hack Arris Cable Modem for Free Internet ?

A cable modem is a piece of hardware that enables your computer to connect via a landline to an Internet service provider. In order to provide access to broadband Internet, it transforms an analog signal into a digital signal. A coaxial cable and subsequently a Cat 5 (Ethernet) cord are used to connect a cable modem to a computer or network router.

One of the quickest broadband options is cable, which provides a noticeable speed increase in Internet performance when compared to a dial-up connection. Examples of cable Internet service providers in the US are Comcast and Time Warner. The Arris cable modem has been chosen as the finest cable modem overall due to its reliable performance that will please the majority of home internet customers who do not pay for high-speed service. Network routers are used to share your Internet connection amongst several PCs.

Uncapping a cable modem often involves complex technical procedures, including setting up a tftp server, altering the cable modem's IP address, and running a dhcp server to deceive it into thinking the configuration file is coming from a local host. There are still many glitches even though portion of the process has been automated, but that is going to change.

Onestep is defined as a 30 megabyte program monster that compiles all the tools required to hack a cable modem into a single utility and conceals them behind a point-and-click user interface that enables the user to choose his or her cable modem make and model, service provider, and new speed (up to 10 mbps). Unemployed American programmer who runs a how-to chat site and has led multiple publicly released automated uncapping tools, onestep is run by a well-known figure in the underground superbroadband community. Smart uncappers are aware of how to evade detection, claims this programmer who goes by the name "Derengel."

Best Modem Available in the Market

1. Netgear CM500

Because it is simple to locate at most outlets, the Netgear CM500 is the best modem currently available. The Netgear CM500 supports speeds of up to 300 Mbps and works with the largest cable providers, which should be sufficient for the great majority of Internet customers worldwide. Look for a faster modem if you have a high-speed plan. The CM500 receives generally positive reviews on Amazon, like our other top cable modem options, despite the fact that the retailer appears to pool reviews for all Netgear modems.

Because of this, it is challenging to understand what customers are saying about this particular model. Positive comments highlight the simple installation process and broad interoperability with several main ISPs. Reliability is a complaint in the bad reviews, which is important to remember given the CM500's one-year guarantee.


  • Solid performance
  • Good compatibility
  • Often cheaper than comparable modems


  • One-year warrant shorter than rivals
  • Indicator lights are hard to see

2. Arris Surfboard SB6183

Due to its reliable performance that will satisfy the majority of home internet users who do not pay for high-speed service, the Arris Surfboard SB6183 has been chosen as our top option for the best cable modem overall. The SB6183 likewise has a two-year warranty, albeit it has been more difficult to locate fresh versions of this modem recently. A refurbished version is not recommended. The all-white SB6183's dimensions of 5.2 x 5 x 2.1 inches allow it to be placed discretely next to a router, cable box, and any other hardware you may have on hand.

I don't like how close the coaxial cable connector is to the power connector, but you're probably just going to have to deal with that when setting up the modem.


  • Dependable
  • Two-year warranty
  • Compatible with most internet providers
  • Visible status lights


  • Awkward placement of the coaxial cable
