The basic steps depend on your mouse type

Most wireless mice connect in one of two ways: USB receiver or Bluetooth. A USB receiver is a small dongle that plugs into your computer's USB port and pairs with the mouse automatically or with a button press. Bluetooth mice connect directly to your computer's built-in Bluetooth radio without needing a separate receiver. The connection process takes less than a minute either way, though the exact steps differ slightly.

Before you start, check your mouse's documentation or the bottom of the device to see which type you have. Most mice come with instructions printed on the box or inside the battery compartment. If you have lost the documentation, the manufacturer's website usually has a quick-start guide you can download by searching for your mouse model number.

Key Takeaways

  • USB receiver mice plug the dongle into any USB port, and most pair automatically without any action from you.
  • Bluetooth mice require you to turn on your computer's Bluetooth, put the mouse in pairing mode, then select it from your computer's Bluetooth settings.
  • If your mouse does not appear during pairing, try replacing the batteries first — a weak battery is the most common reason pairing fails.
  • Once paired, your mouse will reconnect automatically each time you turn it on, as long as Bluetooth stays enabled or the receiver stays plugged in.

Connecting a USB receiver mouse

Plug the USB receiver into any available USB port on your computer. On Windows, the mouse usually works immediately without installing anything. On Mac, the mouse may work right away, but some models require you to download a driver from the manufacturer's website first.

If the mouse does not respond after plugging in the receiver, look for a pairing button on the bottom of the mouse or on the receiver itself. Press and hold it for a few seconds until a light on the mouse or receiver blinks. This tells the two devices to find each other. Most USB receiver mice pair within 10 seconds of pressing the button.

If pairing still does not work, try a different USB port. Some ports on older computers or certain laptops do not provide enough power. Also check that the batteries in the mouse are fresh — even USB receiver mice need working batteries to transmit a signal.

Connecting a Bluetooth mouse

Turn on your computer's Bluetooth. On Windows 10 or 11, go to Settings, then Devices, then Bluetooth & other devices, and toggle Bluetooth on. On Mac, go to System Settings, then Bluetooth, and make sure Bluetooth is on. On Linux, the steps vary by distribution, but Bluetooth settings are usually in the system settings under Connectivity or Devices.

Put your mouse into pairing mode. Most Bluetooth mice have a small button on the bottom or back that you press and hold for three to five seconds until a light blinks or changes color. Some mice enter pairing mode automatically when you turn them on for the first time. Check your mouse's manual to confirm which applies to yours.

Once the mouse is in pairing mode, your computer will show it in the list of available Bluetooth devices. Click or tap the mouse's name to pair it. Your computer may ask you to confirm the pairing or enter a code, but most mice pair without any code. After pairing completes, the mouse should work immediately.

What to do if the mouse does not connect

The most common reason a wireless mouse fails to connect is dead or dying batteries. Replace the batteries with fresh ones and try again. Even if the mouse seems to work, weak batteries can cause connection drops or pairing failures.

If you are using a USB receiver, try plugging it into a different USB port. Some ports are slower or provide less power than others. Avoid USB hubs if possible — plug directly into the computer instead. If you are using Bluetooth, move the mouse closer to your computer. Bluetooth has a range of about 30 feet in open space, but walls and metal objects can reduce that significantly.

On Windows, you can remove and re-pair the mouse. Go to Settings, Devices, Bluetooth & other devices, find the mouse in the list, click it, and select Remove device. Then put the mouse back into pairing mode and pair it again. On Mac, go to System Settings, Bluetooth, find the mouse, click the X next to it, and pair it again.

If the mouse still does not connect after trying fresh batteries and a different port or location, the receiver or Bluetooth chip in the mouse may be faulty. Contact the manufacturer's support team with your mouse model number and the steps you have already tried.

Reconnecting after the first time

Once your mouse is paired, it will reconnect automatically every time you turn it on. You do not need to repeat the pairing process. For USB receiver mice, simply plug the receiver back in or make sure it stays plugged in. For Bluetooth mice, turn on your computer's Bluetooth and turn on the mouse — they will find each other within a few seconds.

If your Bluetooth mouse does not reconnect automatically, check that Bluetooth is still enabled on your computer. Some computers turn Bluetooth off when you restart or put them to sleep. You can also manually select the mouse from your Bluetooth settings if it appears in the list but is not connecting.

Switching a mouse between computers

A USB receiver mouse can switch between computers by simply unplugging the receiver from one computer and plugging it into another. The mouse will work immediately on the new computer.

A Bluetooth mouse can pair with multiple computers, but it can only connect to one at a time. To switch it to a different computer, turn off Bluetooth on the first computer or move the mouse out of range, then turn on Bluetooth on the second computer and turn on the mouse. It will connect to whichever computer's Bluetooth is active and in range.

If you want the mouse to pair with a second computer without unpairing it from the first, put the mouse into pairing mode again and pair it with the new computer. The mouse will remember both computers and connect to whichever one it finds first when you turn it on.

Frequently Asked Questions

Do I need to install software to use a wireless mouse?

Most wireless mice work without installing anything — just plug in the receiver or pair via Bluetooth and start using it. Some mice come with optional software that adds extra buttons or adjusts sensitivity, but this is not required for basic use. Check the manufacturer's website if you want to customize your mouse's behavior.

Can I use a wireless mouse with a laptop?

Yes. Laptops have USB ports for receiver mice and built-in Bluetooth for Bluetooth mice. Bluetooth is often more convenient on a laptop because it does not use a USB port, but either type works fine.

What if my mouse keeps disconnecting?

Replace the batteries first — this fixes most disconnection problems. If that does not work, move the mouse closer to your computer and away from other wireless devices like routers or microwaves, which can interfere with the signal. For USB receiver mice, try a different USB port.

Can I pair a wireless mouse with multiple devices at once?

A Bluetooth mouse can pair with multiple computers or tablets, but it connects to only one at a time. A USB receiver mouse is tied to that specific receiver, so you would need a separate receiver for each computer you want to use it with.

How far away can I use a wireless mouse?

USB receiver mice typically work up to 30 feet away, though this varies by model. Bluetooth mice also work up to about 30 feet in open space, but walls and metal objects reduce the range. Check your mouse's specifications for the exact range.
