Find and select your 2.4 GHz network from the available list
Your router broadcasts two separate networks at the same time: one at 2.4 GHz and one at 5 GHz. The 2.4 GHz band travels farther through walls and works with older devices, while 5 GHz is faster but shorter-range. When you open your device's WiFi settings, you will see both networks listed separately — they usually have the same name with a suffix like "-2.4G" or "-5G", or they may have completely different names if your router is set up that way.
On Windows, click the WiFi icon in the bottom right corner of your taskbar. On Mac, click the WiFi icon in the top right corner of your menu bar. On a phone or tablet, open Settings and look for WiFi or Network settings. Scan through the list of available networks until you find the one labeled with your router's name and the 2.4 GHz identifier. If you do not see a separate 2.4 GHz option, your router may be broadcasting both bands under a single name — in that case, proceed to the next step and your device will connect to whichever band it prefers.
Key Takeaways
- Your router sends out two WiFi networks at once: 2.4 GHz reaches farther but is slower, and 5 GHz is faster but does not go through walls as well.
- Most routers label the 2.4 GHz network with a suffix like "-2.4G" or "-24" so you can tell it apart from the 5 GHz version.
- After you select the network, you will need to enter your WiFi password, which is usually printed on the router itself or in your setup paperwork.
- If your device keeps dropping the connection, check whether your router is too far away or whether interference from microwaves or cordless phones is affecting the signal.
Enter your WiFi password when prompted
Once you select the 2.4 GHz network, your device will ask you to enter a password. This is the WiFi password, not your router's admin password — it is the one you use to let people connect to your internet. If you set up the router yourself, you chose this password during setup. If you inherited the router from a previous owner or tenant, the password may be on a sticker on the back or bottom of the router itself.
Type the password exactly as it appears, including capital letters, numbers, and special characters. WiFi passwords are case-sensitive, so "MyPassword" is different from "mypassword". If you enter it wrong, your device will show an error message and ask you to try again. Once you enter the correct password, your device will connect to the network and you should see a checkmark or "Connected" label next to the network name.
Verify the connection is working
After your device connects, open a web browser and try to load a website like Google.com or your email. If the page loads, your connection is working. If the page does not load or times out, your device may have connected to the network but not yet received an internet signal — wait 30 seconds and try again, as the connection sometimes takes a moment to fully establish.
On Windows, you can also check the connection by clicking the WiFi icon in the taskbar and confirming that the network shows "Connected" underneath its name. On Mac, the WiFi icon in the menu bar will show a filled signal indicator. On phones and tablets, you will see a WiFi symbol in the status bar at the top of the screen. If you see the symbol but the internet is not working, restart your router by unplugging it for 10 seconds, plugging it back in, and waiting two minutes for it to fully restart.
Understand when to use 2.4 GHz instead of 5 GHz
Use 2.4 GHz when your device is far from the router, when you need to connect through multiple walls, or when you are using older devices that do not support 5 GHz. Older smart home devices, printers, and some laptops from before 2015 may only work on 2.4 GHz. The 2.4 GHz band also works better outdoors and in large homes where the router is in one corner and you need coverage everywhere.
The downside is that 2.4 GHz is slower and more crowded — your neighbors' WiFi networks, cordless phones, and microwave ovens all use the same frequency, which can cause interference and dropped connections. If you have a newer device that supports 5 GHz and you are close enough to the router, 5 GHz will give you faster speeds and fewer interruptions. Many modern routers let you use both bands at the same time, so you can connect your phone to 5 GHz for speed while keeping your older smart home devices on 2.4 GHz.
Fix connection problems on 2.4 GHz
If your device connects but the internet is slow or keeps dropping, move closer to the router and try again. The 2.4 GHz band travels farther than 5 GHz, but distance still matters — if you are more than 100 feet away or separated by many walls, the signal weakens. If moving closer fixes the problem, your router may not be in the best location. Consider moving it to a central, elevated spot in your home rather than in a closet or cabinet.
If you are close to the router and the connection is still unstable, check for interference. Microwave ovens, cordless phones, baby monitors, and some wireless speakers all use the 2.4 GHz frequency. Try turning off these devices one at a time to see if one of them is causing the problem. If interference is the issue, either move the interfering device away from the router, switch that device to a different frequency if it has that option, or connect your device to the 5 GHz network instead if it is available and you are close enough.
Reconnect automatically in the future
After you connect once, your device will remember the network and password. The next time you are in range, your device will reconnect automatically without asking for the password again. On Windows and Mac, you can see all the networks your device remembers by opening WiFi settings and looking for a "Manage known networks" or "Preferred networks" option. If you want to stop your device from automatically connecting to a particular network, you can remove it from this list.
If you change your WiFi password, your device will not automatically reconnect — it will show the network as available but will ask for the new password the next time you try to connect. Once you enter the new password, your device will update its memory and reconnect automatically again in the future. This is a security feature: if someone steals your device, they cannot automatically connect to your WiFi using the old password.
Frequently Asked Questions
Why does my device show the WiFi network but say "cannot connect"?
This usually means you entered the password wrong, or the router is not broadcasting the 2.4 GHz band. Check the password on the router itself and try again, making sure to match capital letters exactly. If the password is correct, restart your router by unplugging it for 10 seconds. If the network still does not appear, log into your router's settings and confirm that the 2.4 GHz band is turned on.
Can I use 2.4 GHz and 5 GHz at the same time?
Yes. Your router broadcasts both bands simultaneously, and different devices can connect to different bands at the same time. You might connect your laptop to 5 GHz for speed while your smart home devices use 2.4 GHz. This is called dual-band operation and is standard on most modern routers.
What if I do not see a separate 2.4 GHz network listed?
Your router may be set to broadcast both bands under a single network name, or the 2.4 GHz band may be turned off. Log into your router's settings using a web browser and look for WiFi settings or Band settings. You can usually access this by typing your router's IP address (often 192.168.1.1) into the address bar. If you do not know how to access router settings, check the manual that came with your router.
Will connecting to 2.4 GHz slow down my internet?
The 2.4 GHz band itself is slower than 5 GHz, but your actual internet speed depends on your internet service provider, not your WiFi band. If your internet plan is 100 Mbps, you will get roughly that speed on either band if you are close to the router. The difference is that 5 GHz can deliver that speed more reliably over shorter distances, while 2.4 GHz is more stable over longer distances.
