Uncapping is the process of removing the bandwidth limit set by an ISP on a user’s internet connection. It is often illegal and violates the ToS agreement. Attempts to uncap a modem may result in termination of internet service and legal consequences. In the past, uncapping was possible by altering the configuration file or firmware on a modem, but this is no longer effective as ISPs can detect and update the file.
Uncapping is a process by which a person removes the limitation on their Internet bandwidth provided by the modem and Internet Service Provider (ISP) they use. ISPs use various methods to place a limit or “limit” on the bandwidth a person can use to upload and download files and programs over the Internet. When this limitation is removed, the “cap” is lifted and the user can use higher bandwidth speeds than his ISP intends to provide. Uncapping is often considered illegal and typically violates the terms of service (ToS) agreement between a user and his ISP.
The first thing anyone interested in unblocking their modem should know is that doing so is quite difficult, if not impossible, and that attempts to do so may result in termination of their Internet service. Depending on how a person attempts to break in and the modem they are using, such actions may even be illegal and may result in criminal or civil charges. In other words, someone interested in unblocking their modem and internet bandwidth generally shouldn’t even try to do so.
Removing the cap was entirely possible with older internet technology, especially older modems. The way this worked in the past was basically how a modem connected to the internet. A configuration file on a modem provides information to that modem about how to connect to an ISP network, including the maximum speed for that connection. Different configuration files can be used by a single ISP for multiple users, allowing the same basic service to provide different bandwidth rates for customers who pay different amounts for those services. In the past, uncapping could be achieved by altering this configuration file or the firmware on a modem to remove the bandwidth speed limit placed on the file.
Changing the firmware on a modem usually no longer works, as it doesn’t always bypass the configuration file installed on the modem. This file is typically downloaded from a user’s ISP each time the user initially connects to the ISP’s network, and may also be updated during use. Using a fake configuration file, therefore, typically doesn’t work, as a new file is usually downloaded and installed while connected to an ISP. Changing the firmware on a modem rented from an ISP is generally considered vandalism and can lead to legal consequences. ISPs are also usually able to detect when users attempt to use an altered configuration file or use other methods to remove the limit, and may terminate service for that user as a result of such actions.
