Quick Answer: When your computer not connecting to internet happens, the problem is usually your modem or router, not your computer itself. Turn off both devices, wait 30 seconds, then turn them back on. This simple restart fixes most connection problems. If that doesn’t work, check that your Wi-Fi is turned on and you’re entering the correct password.
- Most internet connection problems are fixed by restarting your modem and router
- Check that your Wi-Fi is actually turned on — it’s easier to switch off than you think
- Make sure you’re typing your Wi-Fi password correctly (capital letters matter)
- Your cable or phone company can check if there’s an outage in your area
- If nothing works after these simple steps, it’s okay to ask for help
Why Won’t My Computer Connect to the Internet?
There are a few common reasons why this happens, and most of them are easy to fix. Your modem or router might need a restart. Your Wi-Fi might be turned off. You might have typed the wrong password. Or your internet service provider like Xfinity or AT&T might be having problems in your area.
The good news? You can check all of these things yourself. Don’t worry — this is easier than it sounds. We’ll walk through each step together.
According to AARP’s 2025 Tech Trends research, 1 in 5 adults 50+ say getting setup and tech support is a barrier to using technology. But most internet connection problems have simple solutions that anyone can do.
How Do I Restart My Modem and Router?
This is the first thing to try, and it fixes the problem about 70% of the time. Your modem is the device your cable or phone line plugs into. Your router is what creates the Wi-Fi signal. Sometimes they’re combined into one box.
- Find your modem and router: Look for the boxes with blinking lights, usually near where your cable or phone line comes into your house. They might be on the floor, on a shelf, or in a closet.
- Unplug both devices: Pull the power cord out of the back of each box. Don’t worry about unplugging any other cords — just the power.
- Wait 30 seconds: This gives the devices time to fully shut down. You can count to 30 slowly.
- Plug in the modem first: Put the power cord back into your modem. Wait until the lights stop blinking (usually 1-2 minutes).
- Then plug in the router: Once the modem lights are steady, plug in your router. Wait another minute or two for it to start up.
- Try connecting again: On your computer, click the Wi-Fi icon and try to connect. It should work now.
This process is called a “power cycle,” and it clears out any temporary glitches. Whether you have Comcast, Spectrum, or another provider, this works the same way.
How Do I Check If My Wi-Fi Is Turned On?
Sometimes Wi-Fi gets turned off accidentally. It’s easy to bump the wrong key or click the wrong button.
On a Windows computer, look in the bottom right corner of your screen. You’ll see a small icon that looks like a fan or radio waves. If you see a red X or a yellow triangle, your Wi-Fi is off or having trouble.
Click that icon. You’ll see a list of available networks. Look for a button or tile that says “Wi-Fi.” Make sure it’s turned on (it should be blue or highlighted).
On a Mac, look in the top right corner for the Wi-Fi symbol. If it has a line through it, click it and choose “Turn Wi-Fi On.”
Don’t worry if you’ve accidentally turned it off before. It happens to everyone. You’ve got this.
Am I Typing My Wi-Fi Password Correctly?
Wi-Fi passwords are picky. Capital letters, lowercase letters, and numbers all have to be exactly right.
Your Wi-Fi password is usually printed on a sticker on your router or modem. Look on the bottom or back of the device. It might say “Password,” “Network Key,” or “Passphrase.”
When you type it in, make sure you’re using capital letters where shown. The number zero (0) looks like the letter O, and the number one (1) looks like the letter l. If you’re not sure, try typing the password in a document first so you can see it clearly.
Many Netgear and Linksys routers come with long, random passwords. They’re hard to type, but they keep your network secure.
Could There Be an Internet Outage in My Area?
Sometimes the problem isn’t in your house at all. Your internet service provider might be fixing something in your neighborhood.
Call your provider’s customer service number. For Xfinity, it’s on your bill. For AT&T or Spectrum, you can find it on their website. Tell them your address and ask if there’s an outage.
Most companies also have outage maps on their websites. You can check these from your smartphone if your computer isn’t working.
If there is an outage, there’s nothing you can do but wait. The company will fix it, usually within a few hours. This isn’t your fault.
What If My Computer Still Won’t Connect?
If you’ve tried restarting your equipment, checked your Wi-Fi is on, and confirmed your password is correct, there might be a setting that needs adjusting.
According to Microsoft’s official guidance, running the built-in troubleshooter can identify problems automatically.
On Windows, click the Start button, type “troubleshoot,” and select “Troubleshoot settings.” Then click “Internet Connections” and follow the prompts. The computer will scan for problems and try to fix them.
On a Mac, you can find similar help through Apple’s support page, which walks you through checking your network settings.
These tools do the technical work for you. Just read each screen and click “Next.”
When Should You Ask for Help Instead of Fixing It Yourself?
You don’t have to solve every tech problem on your own. It’s perfectly okay to ask for help when:
- You’ve tried restarting everything twice and nothing changed
- The troubleshooter says there’s a problem but doesn’t fix it
- You can connect to Wi-Fi but web pages won’t load
- You’re worried you might break something or make it worse
- You just want someone to walk you through it step-by-step

How Can I Prevent This Problem in the Future?
Once you’re back online, there are a few simple things you can do to avoid this headache again.
First, write down your Wi-Fi password and keep it somewhere safe. A small notebook near your computer works great. That way you won’t have to crawl behind your router next time.
Second, restart your modem and router once a month, even when everything’s working fine. This keeps them running smoothly. Pick an easy day to remember, like the first Saturday of each month.
Third, keep your internet provider’s phone number handy. Put it in your phone contacts or stick it on your fridge. You’ll save time if you need to report an outage.
These small habits make a big difference.
Frequently Asked Questions
What’s the difference between my modem and my router?
Your modem connects your home to your internet provider’s network through the cable or phone line. Your router takes that connection and creates Wi-Fi so multiple devices can use it. Some newer devices combine both functions into one box, which makes things simpler.
How long should I wait before calling my internet company?
Try the basic fixes first — restart your equipment, check your Wi-Fi is on, and confirm your password. If nothing works after 15-20 minutes, go ahead and call. They can check for outages and walk you through other steps over the phone.
Can a storm or bad weather affect my internet connection?
Yes, severe weather can temporarily disrupt your connection, especially if you have cable or satellite internet. Lightning, heavy rain, or strong winds can affect the equipment outside your home. The connection usually comes back on its own once the weather clears.
Why does my internet work on my phone but not my computer?
This usually means your Wi-Fi network is working fine, but your computer has a problem connecting to it. Try restarting just your computer first. If that doesn’t work, forget the network on your computer and reconnect by entering the password again fresh.
Is it safe to unplug my modem and router?
Yes, it’s completely safe. These devices are designed to be unplugged and restarted. You won’t lose your settings or damage anything. Just wait the full 30 seconds before plugging them back in so they reset properly.
Should I buy a new router if mine is old?
If your router is more than 5 years old and you’re having frequent connection problems, a new one might help. But try all the simple fixes first. Sometimes what seems like old equipment is just equipment that needs a restart and better placement away from walls or metal objects.
