The three ways to get online, and which one works for your setup
You connect to the internet through your modem and router — the modem talks to your internet provider, and the router broadcasts a wireless signal or accepts a cable from your device. Most homes use Wi-Fi, which means your phone, laptop, and tablet all connect wirelessly to the same router. Some devices connect with an ethernet cable plugged directly into the router for a faster, more stable connection. A few older devices or smart home gadgets may need a separate 2.4 GHz network if your router broadcasts both 2.4 GHz and 5 GHz at once.
The device you're using determines which method makes sense. A laptop or phone will almost always use Wi-Fi. A desktop computer, gaming console, or streaming device might use ethernet if it sits near the router. Smart home devices like security cameras or thermostats usually connect wirelessly but sometimes need the 2.4 GHz band specifically because they don't support the faster 5 GHz standard.
Key Takeaways
- Wi-Fi is the easiest method for phones and laptops — you select your network name from the list, enter your password once, and the device remembers it.
- Ethernet cables plugged into your router give you faster speeds and a more stable connection, but only work for devices that sit close to the router.
- Your router broadcasts a network name (SSID) and password that you set up during initial installation — if you didn't change the default password, do that before connecting devices.
- Some routers split their signal into two bands (2.4 GHz and 5 GHz), and older smart home devices may only see and connect to the 2.4 GHz network.
- Once a device connects successfully, it stores the password and reconnects automatically whenever it's in range — you only enter the password once.
Connecting via Wi-Fi on phones and laptops
Open your device's Wi-Fi settings and look for your router's network name in the list of available networks. The network name is also called the SSID — you set this during router setup, or it came with a default name printed on the router itself. Tap or click the network name, then enter the password when prompted. This password is different from your internet provider's login; it's the Wi-Fi password you created or received with your router.
After you enter the password correctly, your device connects and remembers it. The next time your device is in range of that network, it will connect automatically without asking for the password again. If you see a "connected but no internet" message, the problem is usually between your modem and your internet provider, not between your device and router — restart your modem by unplugging it for 30 seconds, then plug it back in and wait two minutes for it to fully restart.
If your device doesn't see your network name in the list, move closer to the router. Walls, metal objects, and distance all weaken the Wi-Fi signal. If you're still not seeing it after moving closer, restart your router by unplugging it for 30 seconds. If the network name still doesn't appear, log into your router's settings to confirm Wi-Fi is turned on — you do this by opening a web browser and typing your router's IP address, usually printed on the router itself or in your setup paperwork.
Using an ethernet cable for a wired connection
An ethernet cable looks like a thick phone cord with a plastic connector on each end. Plug one end into an available port on the back of your router — most routers have four ports labeled 1 through 4. Plug the other end into the ethernet port on your device. Desktop computers, gaming consoles, and some streaming devices have an ethernet port; phones and tablets do not.
Once the cable is plugged in, your device should connect to the internet automatically within a few seconds. You'll see a wired connection icon in your device's network settings instead of a Wi-Fi icon. Wired connections are faster and more stable than Wi-Fi because the cable carries the signal directly without interference from walls or other devices. If you have a device that will stay in one place — a desktop computer, printer, or gaming console — ethernet is worth the small effort of running a cable.
If your device connects via ethernet but still shows no internet, restart your modem first, then restart your device. If that doesn't work, try a different ethernet port on the router — one of the ports may be damaged. Ethernet cables themselves rarely fail, but if you suspect the cable is the problem, try a different cable if you have one available.
Splitting your network into two bands for older devices
Some routers broadcast two separate networks at once: one at 2.4 GHz and one at 5 GHz. The 5 GHz band is faster but has shorter range; the 2.4 GHz band is slower but travels through walls better. Most modern devices automatically pick the best band, but older smart home devices — security cameras, thermostats, and some smart speakers — only support 2.4 GHz and won't see the 5 GHz network at all.
If you have devices that can't find your network, check whether your router is set to broadcast both bands at once. Log into your router's settings by opening a web browser and typing your router's IP address. Look for a setting called "dual band" or "band steering" and turn it off if it's on. This forces your router to broadcast both 2.4 GHz and 5 GHz as separate networks with different names — your older devices will see the 2.4 GHz network and can connect to it, while your phone and laptop can connect to the faster 5 GHz network.
Some routers let you name the two bands differently, like "MyNetwork-5G" and "MyNetwork-2.4G", so you know which one to connect to. Others use the same name for both and let your device choose. Check your router's manual or the manufacturer's website to find the exact steps for your model.
Troubleshooting when a device won't connect
If a device can see your network but won't connect, the password is usually wrong. Double-check that you're typing the Wi-Fi password, not your internet provider's login password. The Wi-Fi password is printed on a sticker on your router or in the setup paperwork that came with it. Passwords are case-sensitive, so "MyPassword" is different from "mypassword" — type it exactly as it appears.
If you've tried the password multiple times and it's definitely correct, restart both your device and your router. Unplug the router for 30 seconds, plug it back in, and wait two minutes for it to fully restart. Then try connecting again. If the device still won't connect after a restart, forget the network on your device and reconnect. On phones and laptops, this option is usually in Wi-Fi settings under "manage networks" or "known networks" — select your network and choose "forget" or "remove", then reconnect and enter the password again.
If multiple devices can't connect, the problem is likely your router or modem, not the devices. Restart your modem first — unplug it for 30 seconds and plug it back in. Wait two minutes, then restart your router the same way. If devices still can't connect after both restarts, contact your internet provider to confirm your modem is working correctly.
Changing your Wi-Fi password for security
Your router came with a default Wi-Fi password printed on it. This password is the same on thousands of identical routers, so change it to something only you know. Log into your router's settings by opening a web browser and typing your router's IP address — this is usually 192.168.1.1 or 192.168.0.1, printed on the router itself. You'll need to log in with a username and password; these are also printed on the router or in your setup paperwork.
Once you're logged in, look for a section called "Wi-Fi settings", "wireless settings", or "network settings". Find the field labeled "password", "passphrase", or "pre-shared key" and replace the default password with a new one. Make it at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. Write down your new password somewhere safe — you'll need it when you connect your devices.
After you change the password, your router will restart and disconnect all your devices. Once it's back online, reconnect each device by selecting your network name and entering the new password. Your devices will forget the old password and remember the new one instead.
Understanding network names and why they matter
Your router's network name, or SSID, is what you see when you look for available Wi-Fi networks on your phone or laptop. By default, this is usually something like "TP-Link-1234" or "Netgear-Home" — the router manufacturer's name plus a number. You can change it to anything you want, like "MyHome" or "GuestNetwork", by logging into your router's settings.
Changing your network name doesn't affect security or speed — it's purely for convenience. A memorable name makes it easier to find your network when you're connecting a new device. Some people create a separate network name for guests so they can share internet access without sharing their main network password. Check your router's manual to see if it supports a guest network feature.
If you have multiple routers in your home, give each one a different network name so you can tell them apart. This is especially important if you have a mesh Wi-Fi system, where multiple devices work together to cover your whole house — each node may broadcast its own network name, and your device will automatically connect to whichever one has the strongest signal.
Frequently Asked Questions
Do I need to restart my router every time I connect a new device?
No. Your router broadcasts your network name and password constantly, so new devices can find and connect to it without any action from you. You only restart your router if a device can't find the network or won't connect after trying multiple times.
What's the difference between 2.4 GHz and 5 GHz Wi-Fi?
5 GHz is faster but doesn't travel through walls as well. 2.4 GHz is slower but has better range. Most modern devices automatically use 5 GHz when they're close to the router and switch to 2.4 GHz when they're farther away. Older smart home devices only support 2.4 GHz.
Can I use both Wi-Fi and ethernet on the same device?
Yes, but your device will only use one connection at a time. It usually prefers ethernet if both are plugged in, since it's faster and more stable. You don't need to do anything — your device handles the choice automatically.
Why does my Wi-Fi keep disconnecting?
This usually means your device is too far from the router or there's interference from walls, metal objects, or other Wi-Fi networks nearby. Try moving closer to the router or moving the router to a more central location in your home. If the problem continues, restart your router and your device.
Is it safe to use the default Wi-Fi password that came with my router?
No. The default password is the same on thousands of identical routers, so anyone who knows your router model can guess it. Change it to a unique password as soon as you set up your router, using at least 12 characters with a mix of letters, numbers, and symbols.
