Start with the simplest fixes first
Most WiFi problems go away after you restart your router — the box that broadcasts your wireless signal. Unplug it from power, wait 30 seconds, and plug it back in. While it restarts (usually 2 to 3 minutes), restart your phone, laptop, or tablet too. These two steps fix roughly half of all connection problems because they clear out temporary glitches in both devices' memory.
If restarting doesn't work, move closer to the router. WiFi signals weaken with distance and through walls, especially thick ones or those with metal studs. If your connection works fine in the same room as the router but fails in the bedroom or kitchen, the signal straightforward isn't reaching far enough. This tells you the problem is range, not a broken connection.
Key Takeaways
- Restart your router by unplugging it for 30 seconds, then restart the device you're using — this fixes most connection problems.
- Move closer to the router to test whether the problem is weak signal rather than a broken connection.
- Check that your device is actually connected to your own WiFi network, not a neighbor's or a public one.
- If your router is more than five years old, it may not support the WiFi standard your newer devices expect.
- Interference from microwaves, cordless phones, and baby monitors can disrupt WiFi on the 2.4 GHz band — moving the router away from these devices sometimes helps.
Confirm you're connected to the right network
Your device may be trying to connect to the wrong WiFi network without telling you. Open your WiFi settings and look at which network your phone or laptop is currently connected to. The name should match the one printed on a sticker on your router — usually something like "Netgear-5G" or "ASUS-Guest" rather than your neighbor's network name.
If you're connected to the wrong network, forget it and reconnect to your own. On most phones, go to Settings > WiFi, tap the network name you're currently on, and choose "Forget". Then select your own network from the list and enter the password (also on the router sticker). On Windows, go to Settings > Network & Internet > WiFi > Manage Known Networks, find the wrong one, and click "Forget".
Check whether your router needs a software update
Router manufacturers release updates that fix connection problems and improve performance. You usually can't see these updates happening — they install quietly in the background. But if your router is old or has been unplugged for a long time, it may be running outdated software.
To check, open a web browser and type 192.168.1.1 into the address bar (or 192.168.0.1 if that doesn't work). Log in using the username and password on your router sticker. Look for a section called "Administration", "System", or "Firmware" and check whether an update is available. If one is, install it and let the router restart. This process usually takes 5 to 10 minutes.
Understand WiFi bands and why they matter
Most routers broadcast on two different frequencies: 2.4 GHz and 5 GHz. The 2.4 GHz band travels farther through walls but is slower and more crowded — microwaves, cordless phones, and baby monitors all use the same frequency and can interfere. The 5 GHz band is faster and less crowded but doesn't travel as far.
If your router broadcasts both bands, your device may be connecting to the wrong one for your situation. If you're far from the router, you need 2.4 GHz even though it's slower. If you're close and want speed, 5 GHz is better. Check your WiFi settings to see which band you're on. If your router name appears twice in the list (like "MyNetwork" and "MyNetwork-5G"), you can choose which one to use.
Newer routers also broadcast on 6 GHz, which is even less crowded but only works with very new devices. If your phone or laptop is more than three years old, it won't see the 6 GHz network at all.
Move your router to a better location
Where you place your router matters more than most people realize. Put it in a central, elevated location — a shelf in a hallway or living room works better than a closet, basement, or corner. Avoid placing it inside a cabinet, behind a TV, or next to a microwave, cordless phone base, or baby monitor. These devices all broadcast on frequencies that interfere with WiFi.
If your router is currently in a corner of your home, moving it to the center can noticeably improve coverage. If you can't move it (because that's where your internet cable comes in), you might need a WiFi extender — a device that picks up your router's signal and rebroadcasts it to reach farther. Extenders are cheap (usually $30 to $60) but slower than the original signal, so they work best for basic browsing rather than video streaming.
Check whether your device is the problem, not the router
If only one device loses WiFi while others stay connected, the problem is with that device, not your router. Try these steps on the device that's failing: forget the network and reconnect, restart the device, and move it closer to the router. If it still doesn't work, the device's WiFi hardware may be damaged or its software may need updating.
Check whether your phone or laptop has a system update waiting. On iPhones, go to Settings > General > Software Update. On Android, go to Settings > System > System Update. On Windows, go to Settings > Update & Security > Windows Update. Install any available updates and restart the device. Outdated software sometimes causes WiFi problems that newer versions fix.
Know when to replace your router
If your router is more than five years old, it may not support the WiFi standard that newer devices expect. Devices made in the last few years often use WiFi 6 (also called 802.11ax), which older routers don't broadcast. Your device will still connect, but at much slower speeds.
Routers also wear out. If restarting, updating, and repositioning don't help, and multiple devices all have trouble, your router may be failing. A replacement costs $50 to $200 depending on the size of your home and the speed you need. Before buying, check what your internet provider offers — many include a router with your service, and you can swap it for free.
Frequently Asked Questions
Why does my WiFi work fine sometimes but drop out randomly?
Random dropouts usually mean interference from another device on the same frequency, or your router overheating. Try moving your router away from microwaves and cordless phones. If it's in a cabinet or enclosed space, move it to open air. If the problem happens at the same time every day, something in your home or neighborhood is turning on and off at that time.
Can I improve my WiFi speed without buying a new router?
Yes. Move closer to the router, switch to the 5 GHz band if available, and reduce the number of devices connected at once. Restart your router weekly. If many devices are streaming video or downloading at the same time, your internet speed itself may be the limit, not the WiFi. Contact your internet provider to check your plan speed.
What's the difference between WiFi and internet?
WiFi is the wireless signal your router broadcasts. Internet is the service your provider delivers through the cable or phone line coming into your home. You can have WiFi but no internet (router working, but service is down), or internet but no WiFi (service working, but router is broken). If nothing connects, restart your modem — the device the cable plugs into — before restarting the router.
Should I use the guest network instead of my main one?
Guest networks are useful for visitors but slower than your main network because they're intentionally limited. Use your main network for your own devices. Guest networks are good for keeping visitors' devices separate from yours, but don't switch to guest mode to fix a connection problem.
Why does my WiFi password keep asking me to re-enter it?
Your device may have forgotten the password, or the password on your router may have changed. Check the sticker on your router to confirm the password is what you're typing. If you changed the password and forgot it, you can reset the router to factory settings by holding a small button on the back for 10 seconds — this erases all your settings, so only do this as a last resort.
