I still remember the first time this problem hit me.
WiFi icon was full. Phone said Connected. But nothing opened. No Google, no WhatsApp, nothing. At first, I thought my phone was broken. Then I blamed the WiFi company. Later, I realized this issue is very common and usually simple.
When your device shows WiFi connected but no internet, it means your phone or laptop is connected to the router, but the router itself is not properly reaching the internet. This can happen because of router problems, IP or DNS issues, network overload, or even small device setting mistakes.
The good thing is, you don’t need to be a tech expert to fix it.
Common Reasons WiFi Shows Connected but No Internet
Understanding the cause saves a lot of time.
Router Issues
This is the most common reason.
Routers run non-stop for weeks. Sometimes they just get tired. Memory fills up, background errors build, and internet stops even though WiFi stays connected.
I ignored router restarts for months until I learned my lesson.
IP or DNS Problems
Your device needs a valid IP address and DNS to access websites.
If DNS fails or IP conflicts happen, WiFi connects but internet doesn’t load.
This problem usually appears after power cuts or sudden network drops.
Network Congestion
Too many devices connected at once can choke the network.
Smart TVs, phones, laptops, downloads, updates all together can slow or completely block internet access for some devices.
Device Settings Issues
Sometimes the problem is not the router, but your phone or laptop.
Private DNS, VPNs, firewalls, antivirus apps, or incorrect network settings can block internet without warning.
I once spent an hour fixing WiFi only to realize VPN was turned on.
Step-by-Step Fix for WiFi Connected But No Internet
Follow these steps in order. Don’t skip.
1. Restart Router & Device
This step fixes more than 50% of cases.
• Turn off the router
• Unplug it
• Wait 30 seconds
• Plug it back
• Turn it on
Now restart your phone or laptop.
I used to underestimate this step. Now it’s the first thing I do.
2. Forget & Reconnect WiFi
If restart doesn’t work, try reconnecting fresh.
Go to WiFi settings
Tap on your WiFi name
Select Forget Network
Then reconnect and enter password again.
This clears old network cache and authentication issues.

3. Check DNS & IP Settings
This step sounds technical, but it’s easy.
On phone or laptop WiFi settings:
Set IP settings to DHCP / Automatic
Set DNS to Automatic
If still not working, try manual DNS:
8.8.8.8
8.8.4.4
Google DNS fixed my internet once when nothing else worked.
4. Update Router Firmware
Most people never do this. I didn’t either.
Old router firmware can cause internet drops, DNS bugs, and connection errors.
Login to router admin panel
Check firmware update section
Install latest update if available
After updating, my random disconnections completely stopped.
5. Contact Internet Provider
If nothing works, the issue might be outside your home.
Possible reasons:
• Line fault
• Area outage
• Account issue
• Speed limit exceeded
Once, I blamed my router all day. ISP later told me there was maintenance in my area.
Always confirm.
Tips to Avoid WiFi Internet Problems
Once your internet works again, these habits help avoid future issues.
Place Router Properly
Don’t hide router behind TV or walls.
Best place:
• Center of house
• Elevated position
• Open area
Signal strength matters more than people think.
Avoid Too Many Heavy Devices
Limit background downloads.
Pause updates when not needed.
Disconnect unused devices.
One device downloading large files can slow internet for everyone.
Use Latest Router Firmware
Check firmware every few months.
This improves:
• Stability
• Speed
• Security
Outdated firmware causes silent problems.

WiFi connected but no internet is one of the most frustrating problems, especially when everything looks normal on the screen. In most cases, the issue is caused by router glitches, DNS or IP conflicts, network congestion, or simple device setting mistakes. By restarting the router, reconnecting WiFi, fixing DNS settings, and keeping router firmware updated, you can solve this issue without calling a technician. Always start with basic fixes before assuming serious damage.
FAQs
Why does WiFi work on some devices but not others?
This usually happens due to device-specific settings, DNS issues, or background apps blocking internet access.
Can antivirus or firewall block WiFi internet?
Yes. Some antivirus apps or firewalls block internet traffic even when WiFi is connected.
How can I check if my router is faulty?
Connect another device or try a different router. If internet still doesn’t work, the router may be faulty.
