Why ISPs Provide Access Points Instead of Routers: demystifying the Connection

When it comes to setting up internet connectivity, many wonder why their ISP (Internet Service Provider) provides an access point instead of a full-fledged router. This article aims to clarify the reasons behind this practice and explain the technicalities involved in the connection process.

Understanding the Infrastructure and Components

The initial encounter with internet connectivity can be confusing, especially when the ISP presents you with a dual-box system. One of these boxes, labeling the WAP (Wireless Access Point), has multiple Ethernet sockets, while the other is a cable modem. The confusion often arises from the technical differences between a WAP and a router.

The signal from the ISP does not come into a router by default but into a modem. The term modem originates from the combination of "modulator" and "demodulator." It converts the incoming digital signal from the ISP into a format that can be transmitted through your home network. This digital data stream then travels to a router, which is responsible for directing the data flow based on the network settings. The switch follows these instructions to route the data to the appropriate device within your network. Lastly, the Wireless Access Point (WAP) connects devices wirelessly to the network.

ISP Gateways: A Unified Device

For simplicity and efficiency, ISPs often provide a single device (known as a Gateway) that integrates all these functionalities in one package. These gateways are purchased in bulk by ISPs from companies that offer good deals, allowing them to provide a uniform experience across all customers. Having a consistent model ensures simpler and more uniform support for technical issues.

Customization and Flexibility

While the ISP’s gateway serves a practical purpose, it can sometimes limit user flexibility. Many users prefer to have their own router for several reasons. Firstly, some prefer to turn off the default router provided by the ISP. In such cases, the WAP and cable modem functions can be utilized by connecting them to a self-chosen router (using Ethernet cables), essentially creating a custom network setup. Others might find that the wireless ISP gateway lacks Ethernet ports for various reasons, such as cost or design decisions.

Why Does the ISP Offer This Option?

ISPs aim to provide the least expensive and most cost-effective solution to their customers. By offering a gateway that includes all necessary components, they can reduce costs and simplify the setup process for users. However, for those who demand more control or better performance, purchasing individual components and combining them with a personal router might be a better option.

Conclusion

In conclusion, the choice between an ISP-provided gateway and a personal router largely depends on user needs and preferences. While gateways simplify the setup and maintenance process, granting users control over their network through a personal router can offer greater customization and flexibility. Understanding the technical differences can help users make an informed decision about which solution is right for them.
