An access point is a device that broadcasts a wireless network so your phone, laptop, or tablet can connect to the internet
An access point 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 turns it into a wireless signal that devices can join. Think of it as a translator: it converts the wired connection into radio waves that your phone or computer can receive and use.
The access point itself does not create the internet. It only shares an existing connection wirelessly. You still need that wired connection coming in from your internet service provider, either through a modem or an existing router. The access point then broadcasts that signal so devices within range can use it without needing a cable.
Many people confuse access points with routers because they look similar and do overlapping jobs. The difference is that a router also handles the job of directing traffic between devices and managing which device gets to use the connection when multiple devices are online at once. An access point is simpler — it just broadcasts the signal and lets devices connect to it.
Key Takeaways
- An access point broadcasts a wireless network from a wired internet connection, letting devices connect without cables.
- Access points are different from routers: a router manages traffic between devices, while an access point only shares the signal.
- You can add an access point to an existing network to extend wireless coverage to dead zones in your home or office.
- Access points need to be plugged into power and connected to your existing network with an ethernet cable to work.
When you might need an access point instead of a router
If you already have a working router and internet connection, but your wireless signal does not reach certain rooms or areas, an access point can extend that coverage. You plug it in somewhere between your router and the dead zone, connect it to your router with an ethernet cable, and it broadcasts the same network so devices can connect from that new location.
Access points are also useful in offices, schools, or larger buildings where one router cannot cover the whole space. Instead of buying a new router, you can add multiple access points throughout the building, all connected back to the same main router. This keeps the network simple to manage while giving good coverage everywhere.
Some people also use access points in situations where they want to keep their main router in one specific location — like a closet or basement where the modem is — but need wireless coverage in the living areas. The access point goes in a central location and handles the wireless broadcasting while the router stays hidden away.
How an access point connects to your network
An access point needs two connections to work: power and a network connection. You plug it into an electrical outlet, then run an ethernet cable from your router (or from another access point) into the ethernet port on the access point. Some newer access points can also connect wirelessly to your router, but a wired connection is more reliable and faster.
Once it is plugged in and connected, you usually need to set it up through a web browser or a phone app. You log into the access point using a default username and password (which comes in the manual or on a sticker on the device), then configure it to broadcast the same network name and password as your main router. This way, devices can roam between the access point and the router without losing connection.
Some access points have a setup button that automatically copies the network settings from your router, making the process much faster. Check your device manual to see if yours has this feature.
Access points versus mesh systems and range extenders
An access point is not the same as a mesh system or a range extender, even though all three can improve wireless coverage. A range extender is the simplest: it picks up your existing wireless signal and rebroadcasts it, but this usually slows down your connection because it is using the same radio channel to receive and send at the same time. An access point is faster because it connects back to your router with a wired cable, so it does not have that slowdown.
A mesh system is more advanced and more expensive. It uses multiple devices that work together as one unified network, automatically directing your device to whichever unit has the strongest signal. Mesh systems are designed to be easier to set up and manage than access points, but they cost more and require replacing your entire router setup.
If you already have a router you like and just need to fill in coverage gaps, an access point is usually the cheapest and most straightforward choice. If you are starting from scratch or your current router is old, a mesh system might be worth considering.
What to look for when choosing an access point
The main thing to check is whether the access point supports the same wireless standard as your router — usually WiFi 6 (also called 802.11ax) or WiFi 5 (802.11ac) for newer devices. If your router is WiFi 6 and you buy a WiFi 5 access point, the access point will work, but it will be slower than your router and may become a bottleneck.
You should also check the number of ethernet ports. Most access points have at least one port for connecting back to your router, but some have extra ports if you want to plug in devices like printers or computers that need a wired connection. The physical size and appearance matter too — some access points are designed to mount on a wall or ceiling, while others sit on a shelf or desk.
Power consumption is worth a quick look if you are adding multiple access points. They do not use much electricity, but a few watts per device adds up over time if you are running several of them.
Setting up an access point in your space
The best location for an access point is somewhere central between your router and the area you want to cover, and as high up as possible — on a shelf, mounted on a wall, or in a ceiling if you have access. Walls, metal objects, and water (like aquariums) block wireless signals, so try to avoid placing the access point behind or inside cabinets or in corners.
Run an ethernet cable from your router to the access point. This cable can go through walls, under carpets, or along baseboards — it does not have to be visible. If running a cable is not practical, some access points support wireless backhaul, meaning they can connect to your router wirelessly instead, though this is slower than a wired connection.
Once the access point is powered on and connected, log into it through a web browser or app and configure it to use the same network name and password as your main router. Some access points let you give them a different name so you can see which one you are connected to, which is helpful for troubleshooting, but this is optional.
Troubleshooting common access point problems
If your access point is not showing up as a network you can join, check that it is powered on, that the ethernet cable is plugged in firmly on both ends, and that you have waited at least a few minutes for it to fully start up. Most access points have a light that indicates whether they are working — check your manual to see what the lights mean.
If the network appears but devices cannot connect to it, make sure you are using the correct password. If you changed the password on your main router but not on the access point, the passwords will not match and devices will fail to connect. Log back into the access point and update the password to match.
If the connection is very slow, check whether the access point is connected to the router with an ethernet cable or wirelessly. A wireless connection is much slower, so if you set it up that way, consider running a cable instead. Also check that the access point is not too far from the router — most need to be within reasonable range to maintain a strong backhaul connection.
Frequently Asked Questions
Can I use an access point without a router?
No. An access point needs an existing internet connection to share. That connection usually comes from a router or modem. If you do not have a router, you need one first, or you need a device that combines a router and modem in one unit.
Do I need to restart my access point if I restart my router?
You do not have to, but it can help if the access point loses connection to the router. Most access points will automatically reconnect once the router comes back online. If it does not, unplugging the access point for 30 seconds and plugging it back in usually fixes it.
Can I have multiple access points on the same network?
Yes. You can add as many access points as you need, as long as they are all configured with the same network name and password. Devices will automatically switch between them as you move around, though the handoff is not always instant.
What is the difference between an access point and a WiFi extender?
A WiFi extender picks up your wireless signal and rebroadcasts it, which slows down the connection. An access point connects back to your router with a wired cable, so it does not have that slowdown. Access points are faster but require running a cable.
Will an access point improve my internet speed?
No. An access point can only share the speed you already have. It will not make your internet faster, but it will let you get the full speed in areas where the signal was weak before.
