A wireless access point is a device that broadcasts a Wi-Fi signal so other devices can connect to your network

A wireless access point (often called an access point or AP) is a piece of hardware that takes an internet connection from a wired source — usually an ethernet cable plugged into a modem or router — and broadcasts it as a Wi-Fi signal that phones, laptops, and tablets can join. It is not the same as a router. A router handles the traffic between your devices and the internet; an access point only broadcasts the signal and lets devices connect to the network that already exists.

Most homes use a combination device that acts as both router and access point in one box. But in larger homes, offices, or buildings where a single router's signal does not reach every corner, people add standalone access points to extend coverage. The access point connects back to the main router through an ethernet cable or, in some cases, wirelessly.

Key Takeaways

  • An access point broadcasts Wi-Fi but does not route internet traffic — it extends an existing network rather than creating a new one.
  • Most home routers include a built-in access point, so you may already own one without realizing it.
  • Standalone access points are useful when your router's signal does not reach all areas of your home or office.
  • An access point needs to connect back to your router or modem with an ethernet cable to function.
  • Access points work on the same Wi-Fi standards (802.11ac, Wi-Fi 6, etc.) as routers and support the same devices.

How an access point differs from a router

A router is the device that decides where data goes — it connects your home network to the internet and manages which packets go to which device. An access point does not make those decisions. It simply receives data from the router (through an ethernet cable) and broadcasts it wirelessly to nearby devices.

Think of a router as a post office that sorts mail and decides where it goes. An access point is a mailbox that lets people drop off and pick up letters in a convenient location. You need the post office (router) to function at all, but you might add mailboxes (access points) in different neighborhoods so people do not have to walk as far.

In practice, most consumer routers sold for home use include an access point built in. When you buy a "Wi-Fi router" for your home, you are buying a device that does both jobs. Standalone access points are separate devices you add to the network when you need more coverage.

When you would add a standalone access point

A single router in the center of your home usually covers most rooms adequately, but walls, distance, and interference can create dead zones where the signal is weak or absent. If your bedroom is far from the router and your connection drops, or if your backyard has no usable signal, adding an access point in a central location between the router and the weak area can help.

Offices and larger buildings often use multiple access points spread throughout the space, all connected back to a central network switch or router. This setup lets someone move from one room to another while staying connected to the same network without dropping the connection.

Access points are also useful if you want to keep your router in a closet or utility room for aesthetic reasons — you can place the access point in a more central location and still get good coverage throughout your home.

How to connect an access point to your network

A standalone access point needs a physical ethernet cable running from your router to the access point. This cable carries the internet connection and the data that the access point will broadcast. Without this cable, the access point has nothing to broadcast.

Once the cable is connected, you power on the access point and use its setup app or web interface to configure it. Most modern access points let you name the Wi-Fi network (the SSID) and set a password. Some access points can be set to use the same network name and password as your main router, so devices automatically switch between them as you move around your home. Others create a separate network you join manually.

The setup process usually takes a few minutes and does not require technical knowledge. The access point's instructions will walk you through connecting to its temporary setup network, entering your main network details, and confirming the connection.

Wi-Fi standards and speed on access points

Access points support the same Wi-Fi standards as routers: 802.11ac (Wi-Fi 5), Wi-Fi 6 (802.11ax), and older standards like 802.11n. The standard determines the maximum speed the access point can broadcast. A Wi-Fi 6 access point is faster than an 802.11ac one, but only if your devices also support Wi-Fi 6.

The speed you actually experience depends on three things: the standard the access point uses, the standard your device supports, and the distance and obstacles between them. A Wi-Fi 6 access point will not make an older phone faster if that phone only supports Wi-Fi 5. Similarly, sitting far from the access point or separated by thick walls will reduce speed even with the newest standard.

When choosing an access point, match it to the standard your devices use. If most of your devices are older, a Wi-Fi 5 access point is usually sufficient and costs less. If you have newer devices or plan to keep the access point for many years, Wi-Fi 6 offers better performance and efficiency.

Mesh systems versus traditional access points

A mesh Wi-Fi system is a newer approach to extending coverage. Instead of one router and separate access points, a mesh system uses multiple identical units that all work together as one network. They communicate with each other wirelessly (though they can also use ethernet cables) and automatically route data through whichever unit is closest or least congested.

Traditional access points are simpler and cheaper. They connect back to a central router with an ethernet cable and broadcast the same network. Mesh systems are more flexible — you can place units anywhere without running cables, and they handle handoff between units more smoothly. The trade-off is that mesh systems cost more and require all units to be from the same brand and product line.

For a small home or apartment, a single router is usually enough. For a larger space, you can choose between adding a traditional access point (cheaper, requires a cable) or upgrading to a mesh system (more expensive, no cables needed).

Common access point brands and where to find them

Major router manufacturers also make standalone access points. Netgear, TP-Link, ASUS, Ubiquiti, and Aruba all sell access points for home and office use. Some are designed for consumers and cost between $50 and $200. Others are built for businesses and cost more but offer advanced features like centralized management and higher capacity.

You can find consumer access points at electronics retailers like Best Buy, online at Amazon, or directly from the manufacturer. If you already own a router from a particular brand, buying an access point from the same brand often makes setup easier because they are designed to work together.

Before buying, check your router's documentation or the manufacturer's website to see if they recommend specific access point models. Some routers work better with certain access points, and using compatible hardware can save troubleshooting time.

Frequently Asked Questions

Can I use an access point without a router?

No. An access point needs a source of internet to broadcast. That source is usually a router connected to your modem. Without a router providing the connection, an access point has nothing to share and will not work.

Do I need to run an ethernet cable to my access point?

Traditional access points require an ethernet cable for the best performance and reliability. Some newer access points can connect wirelessly to your router, but this reduces speed because the access point uses part of its bandwidth to communicate with the router. A wired connection is always preferable if you can run a cable.

Will an access point improve my internet speed?

An access point extends coverage to areas with weak signal, which can improve speed in those locations. It does not increase your overall internet speed from your provider. If your internet plan is 100 Mbps, an access point will not make it faster than 100 Mbps — it just makes that speed available in more places.

Can I use access points from different brands together?

Yes, as long as they support the same Wi-Fi standard. An ASUS access point and a Netgear access point can both broadcast the same network name and work together. However, they will not communicate with each other or hand off devices automatically — each one is independent. For seamless handoff, use access points from the same brand and product line, or use a mesh system.

What is the difference between 2.4 GHz and 5 GHz on an access point?

Most access points broadcast on both frequencies. The 2.4 GHz band has longer range but slower speed and more interference from other devices. The 5 GHz band is faster but does not travel as far through walls. Your device automatically chooses which band to use, or you can manually select one in your Wi-Fi settings.
