The basic steps to connect your wireless mouse
A wireless mouse connects to your computer through a small receiver (called a dongle) that plugs into a USB port, or through Bluetooth if your computer has it built in. Most wireless mice work the same way: you insert batteries, turn on the mouse, and then pair it with your computer. The whole process usually takes less than a minute.
The exact steps depend on whether your mouse uses a USB receiver or Bluetooth. A USB receiver is simpler — you just plug it in and the mouse usually connects automatically. Bluetooth requires you to go into your computer's settings and pair the devices manually, but it means one fewer cable on your desk.
Key Takeaways
- USB receiver mice plug into any USB port and connect automatically without any settings changes.
- Bluetooth mice require you to turn on pairing mode on the mouse, then search for it in your computer's Bluetooth settings.
- If your mouse does not connect, check that batteries are installed correctly and the receiver is fully inserted into the USB port.
- Most wireless mice have a small button on the bottom or side that turns pairing mode on — hold it for three to five seconds until a light blinks.
Connecting a USB receiver mouse
If your mouse came with a small USB receiver, this is the fastest way to connect. Look for a small rectangular or cylindrical piece of plastic about the size of a USB flash drive — this is the receiver. On the bottom or back of your mouse, there is usually a small compartment or button that stores or ejects the receiver.
Insert two AA or AAA batteries into the mouse (check the label inside the battery compartment for which size). Make sure the batteries are oriented correctly — the flat end should face the spring. Close the battery compartment. Plug the USB receiver into any open USB port on your computer (the back of a desktop tower, the side of a laptop, or a USB hub). Your mouse should light up or show a solid light within a few seconds, which means it is connected and ready to use.
If the light does not appear, unplug the receiver and plug it back in. If that does not work, try a different USB port. Some USB ports on older computers or hubs do not provide enough power — moving to a different port usually fixes this.
Connecting a Bluetooth mouse
Bluetooth mice do not need a receiver — they connect directly to your computer's built-in Bluetooth radio. First, insert batteries into the mouse and close the battery compartment. Look for a small button on the bottom or side of the mouse, usually labeled with a Bluetooth symbol (looks like a sideways "B" made of dots). Hold this button down for three to five seconds until you see a light blink on and off repeatedly. This means the mouse is in pairing mode and searching for your computer.
On your computer, open the Bluetooth settings. On Windows, click the Start button, type "Bluetooth settings" into the search box, and press Enter. On Mac, click the Apple menu in the top left, select "System Settings," then click "Bluetooth." Your computer will show a list of devices it finds nearby. Look for your mouse's name (it is usually printed on the box or the bottom of the mouse) and click it. Your computer will pair with the mouse, and you should see "Connected" next to its name.
If your mouse does not appear in the list, make sure the pairing button is still held down and the light is still blinking. If it has stopped blinking, press the button again. Wait ten to fifteen seconds for your computer to find it. If the mouse still does not appear, restart your computer and try again.
What to do if your mouse will not connect
The most common reason a wireless mouse does not connect is dead or incorrectly installed batteries. Open the battery compartment and remove the batteries. Look at the inside of the compartment — you should see a diagram showing which way the batteries go. The flat end (marked with a minus sign) should face the spring. Reinsert the batteries correctly and close the compartment. Try connecting again.
If you are using a USB receiver, make sure it is pushed all the way into the USB port. A receiver that is only partially inserted will not work. Push it in firmly until you feel it click or seat fully. If it still does not work, try a different USB port on your computer — avoid USB hubs if possible, as they sometimes do not provide enough power.
For Bluetooth mice, make sure your computer's Bluetooth is actually turned on. On Windows, open Bluetooth settings and look for a toggle switch at the top — it should be blue or "On." On Mac, click the Bluetooth icon in the top menu bar and make sure it says "Bluetooth: On." If Bluetooth is off, turn it on and try pairing the mouse again.
Replacing batteries and keeping your mouse working
Wireless mice run through batteries over time, usually lasting several months depending on how much you use the mouse. When the mouse starts moving slowly or stops responding, it is time to replace the batteries. Open the battery compartment, remove the old batteries, and insert new ones in the correct direction. You do not need to re-pair the mouse — it will start working immediately.
Keep your mouse and receiver (if you have one) away from metal objects and other wireless devices. Metal can block the signal, and devices like microwave ovens or cordless phones can interfere with the connection. If your mouse keeps disconnecting, try moving the receiver closer to the mouse or moving the mouse away from other electronics.
Using your mouse after it connects
Once your mouse is connected, you should be able to move the cursor on your screen by moving the mouse. Click the left button to select things, and click the right button to open menus. If you have a scroll wheel in the middle, roll it up and down to scroll through web pages and documents. Some wireless mice have extra buttons on the side — these usually go back and forward in web browsers, but you can change what they do in your computer's settings if you want.
If the cursor moves too slowly or too fast, you can adjust the speed in your computer's settings. On Windows, open Settings, click "Devices," then "Mouse," and look for "Pointer speed." On Mac, open System Settings, click "Mouse," and adjust the "Tracking speed" slider. Moving the slider to the right makes the cursor move faster.
Frequently Asked Questions
Can I use a wireless mouse with a laptop?
Yes. If your laptop has a USB port, you can use a USB receiver mouse. If your laptop has Bluetooth (almost all modern laptops do), you can use a Bluetooth mouse. Bluetooth is often better for laptops because it does not use up a USB port, which are usually limited on laptops.
What if I lose the USB receiver?
You can buy a replacement receiver from the mouse manufacturer, but it is usually cheaper to buy a new wireless mouse. Some receivers are universal and work with multiple mouse models from the same brand, so check the manufacturer's website to see if a replacement is available and what it costs.
Can I connect multiple wireless mice to one computer?
Yes. You can plug in multiple USB receivers into different USB ports, or pair multiple Bluetooth mice through your settings. However, only one mouse cursor will appear on screen — your computer will use whichever mouse you move last. This is useful if you want to switch between mice, but not if you want to control two cursors at once.
Why does my mouse keep disconnecting?
The most common cause is weak batteries. Replace them with fresh ones. If that does not work, move the USB receiver closer to the mouse, or move the mouse away from other electronics like microwave ovens or cordless phones. For Bluetooth mice, make sure your computer's Bluetooth is turned on and the mouse is within 30 feet of the computer.
Do I need to install software for my wireless mouse?
Most wireless mice work without any software — just plug in the receiver or pair via Bluetooth and you are done. Some mice come with software that lets you customize buttons or adjust sensitivity, but this is optional. Check the box or the manufacturer's website to see if software is available for your model.
