WiFi Connected But No Internet? What to Check and How To Fix It

What It Means When WiFi Says “Connected” But There’s No Internet

WiFi and internet are related, but they’re not the same thing.

WiFi “connected” usually just means your device has connected to your router (or a mesh/extender) over wireless. That’s the local link.

Internet access means your router also has a working connection out to the internet through your NBN box, modem, or provider.

So when you see “WiFi connected but no internet”, it usually means one of these is broken:

• The internet link is down (NBN/provider outage, modem not connected)
• The router is up but can’t translate traffic properly (DNS issues are a classic)
• Your device connected, but got bad network settings (IP/DHCP issues, VPN, Private DNS, captive portal)

The fastest way to narrow it down is the next step: work out if it’s one device or everything.

First Check: Is It One Device Or All Devices?

Before you touch any settings, do this quick test:

• Try another device on the same WiFi (phone, laptop, TV)
• Or try the same device on mobile data (or a different WiFi)

This tells you where the problem actually is.

If It’s All Devices (Router, NBN, ISP)

If everything connected to that WiFi has no internet, the issue is usually:

• modem/NBN connection is down
• router has lost its internet link
• DNS is broken at the router level
• the ISP is having an outage

In that case, the fixes are mostly router/modem and ISP checks.

If It’s One Device (Phone, Laptop, TV)

If other devices are fine, the internet is working, and the problem is likely:

• that device has a bad IP address
• VPN or Private DNS is blocking it
• the device needs a WiFi reset
• there’s a captive portal it hasn’t accepted yet (hotels, guest WiFi, public WiFi)

Quick Checks That Fix It A Lot Of The Time

Check The Modem/Router Lights

You’re looking for one simple thing: does the router think it has an internet connection?

What to check (labels vary by brand):

• Power should be solid
• Internet / WAN / Online should be solid (or at least not red)
• DSL (on some services) should be solid
• WiFi being on only tells you WiFi is broadcasting, not that the internet is working

If you have an NBN box (the separate wall box), check that looks normal too. If the NBN box is unhappy, the router can still show WiFi “connected” while the internet is dead.

Power Cycle The Right Way (Modem First, Then Router)

This fixes a surprising number of “connected but no internet” problems.

1. Turn off the router
2. Turn off the modem/NBN box (if you have a separate one)
3. Wait 60 seconds
4. Turn the modem/NBN box back on first
5. Wait until it looks fully online (often 2 to 5 minutes)
6. Turn the router back on
7. Wait another minute, then test again

If you just reboot the router, you sometimes end up reconnecting to the same broken session.

Try Mobile Data Or Another Network To Compare

This is a quick reality check.

• If websites work on mobile data, the problem is your home internet, not the website.
• If nothing works anywhere, it might be the device (or a DNS/VPN issue).

If It’s All Devices: Common Causes And Fixes

If every device on the WiFi has no internet, think “router, modem/NBN, or provider”, not “my phone is broken”.

NBN Or ISP Outage (How To Tell)

Quick ways to tell:

• Check if mobile data works on your phone. If yes, it’s not “the internet”, it’s your home connection.
• Ask someone nearby (same building or neighbour) if they’re out too, especially if they’re with the same provider.
• If you can, check your provider’s service status in their app or website.

If it’s an outage, there’s not much you can do except wait, or contact the ISP for an ETA.

Modem Has Dropped Connection

Sometimes the modem or NBN connection drops, but the WiFi keeps working, so everything looks “connected” even though there’s no internet.

Try this:

• Do the proper power cycle again (modem/NBN box first, then router).
• Check the WAN/Internet light on the router. If it’s off or red, the router isn’t getting a live internet connection.
• If you’ve got separate gear, make sure the cable from the modem/NBN box to the router is plugged into the WAN/Internet port, not a LAN port.

If it keeps dropping, it can be a line issue, a failing modem/router, or a provider problem.

DNS Issues (WiFi Works, Web Doesn’t)

DNS is basically the thing that turns “google.com” into an IP address your router can actually reach.

When DNS breaks, it can look like:

• websites won’t load
• apps say “no internet”
• but the WiFi stays connected

A simple test:

• Try opening a few different sites and apps.
• If nothing loads, but your router looks “online”, DNS is a likely suspect. To confirm if your provider's servers are completely unresponsive or just lagging, you can run a quick dns speed test.

A common quick fix is rebooting the router. If it keeps happening, changing DNS can help, but it’s better to do that once you’ve confirmed the cause (otherwise you end up with random settings you don’t understand later).

Router Handing Out Bad IP Addresses (DHCP Problems)

DHCP is what gives each device an address on your network.

When it’s broken, you can see:

• devices connect to WiFi but can’t reach anything
• it might say “connected, no internet” on everything

The quick fix is often:

• reboot router
• forget WiFi on one device, reconnect, and see if anything improves

If a reboot fixes it for 10 minutes then it breaks again, the router may be struggling or misconfigured.

If It’s Only One Device: Common Causes And Fixes

If everyone else is online and one device is the problem, you can usually fix it without touching the router.

Forget The Network And Reconnect

This is the first thing I do on phones and laptops.

• On the problem device, Forget the WiFi network
• Reconnect and re-enter the password
• Test again

It clears out a bad saved setting and forces a fresh connection.

Turn Off VPN, Proxy, Or “Private DNS”

These can make it look like you have “no internet” even when the WiFi is fine.

Try this for a quick test:

• Turn off any VPN
• If you use a work proxy, disconnect and test at home
• On Android, check Private DNS (set it back to Automatic for testing)

If the internet instantly works, you’ve found the culprit.

Time/Date Being Wrong (Yes, It Breaks Internet)

If the device time is way off, a lot of secure websites and apps won’t load properly.

Check:

• Date and time set to Automatic
• Correct time zone

The Device Got A Weird IP Address

Sometimes a device connects but ends up with a “bad” network address and can’t actually reach the router properly.

Easy signs:

• It connects, but nothing works
• It works on other WiFi networks fine

Quick fix options:

• Turn WiFi off and on again
• Restart the device
• Forget and rejoin the network (again)

If it’s a laptop, moving to the Windows/Mac sections later will give you a more direct reset.

Captive Portals (Hotels, Guest WiFi, Public WiFi)

This is super common in hotels, cafes, gyms, and some guest networks.

Your phone or laptop connects, but you actually need to accept a login page first.

Try:

• Open a browser and go to a plain site like neverssl.com
• Or disconnect and reconnect, then watch for the pop-up login page

If it’s a hotel WiFi, you might be connected but blocked until you accept their terms or enter a room number.

Windows Fixes (Windows 10 And Windows 11)

Network Troubleshooter And Adapter Reset

Start with the built-in stuff. It’s not magic, but it does catch simple misconfig.

1. Go to Settings
2. Network & internet
3. Run Network troubleshooter (or “Troubleshoot” under WiFi)

If that doesn’t help, do a proper network reset:

1. Settings
2. Network & internet
3. Advanced network settings
4. Network reset

Heads up: Network reset can remove saved WiFi networks and some VPN settings. You’ll need to reconnect after the restart.

Flush DNS And Reset The Network Stack

1. Right-click Start
2. Open Windows Terminal (Admin) or Command Prompt (Admin)
3. Run these commands:

ipconfig /flushdns
ipconfig /release
ipconfig /renew
netsh winsock reset
netsh int ip reset

Then restart the PC and test again.

Quick clue:

• If ping 8.8.8.8 works but ping google.com fails, it’s usually DNS.
• If both fail, it’s more likely the router, ISP, or the adapter itself.

Disable And Re-Enable The WiFi Adapter

Option A (fast):

1. Settings
2. Network & internet
3. Toggle WiFi off, wait 10 seconds, toggle it back on

Option B (more forceful):

1. Right-click Start
2. Device Manager
3. Expand Network adapters
4. Right-click your WiFi adapter
5. Disable device, wait 10 seconds, then Enable device

After A Windows Update (What Changes)

If this started right after an update, it’s often one of these:

• a driver changed (WiFi adapter driver)
• VPN or security software started filtering traffic
• a proxy got set

Quick checks:

• Restart the PC (proper restart, not sleep)
• Temporarily turn off VPN
• Check proxy is off: Settings > Network & internet > Proxy

iPhone And Android Fixes

iPhone: Private WiFi Address And Network Reset

If it’s only your iPhone doing it, these two fixes solve a lot.

Toggle Private WiFi Address:

1. Settings > Wi-Fi
2. Tap the i next to your network
3. Toggle Private Wi-Fi Address off, wait 10 seconds, then back on
4. Test

Reset Network Settings:

1. Settings > General > Transfer or Reset iPhone
2. Reset > Reset Network Settings
3. Reconnect to WiFi and test

Note: this removes saved WiFi networks and some VPN settings.

Android: Private DNS, Random MAC, And Network Reset

1. Check Private DNS:

• Settings > Network & internet > Private DNS
• Set to Automatic (for testing)

1. Turn off VPN
2. Forget and rejoin the WiFi:

• Press and hold your WiFi network
• Forget
• Reconnect and test

1. Reset network settings:

• Search “Reset network settings” in Settings and run it, then reconnect

Mac Fixes

Renew DHCP Lease

1. System Settings
2. Network
3. Select Wi-Fi
4. Details
5. TCP/IP
6. Renew DHCP Lease

Then test again.

DNS And Network Service Reset

Easy things to try:

• Turn WiFi off and on
• Forget the network and reconnect
• Restart the Mac

If it still won’t play nice, it’s usually DNS settings, a VPN/proxy, or something in the network profile.

Extenders, Mesh, And “Connected But No Internet”

Extender Connected To The Router But Not The Internet

Common fixes:

• Reboot the extender and the router
• Move the extender closer to the router
• Make sure the extender is connected to the correct WiFi network

Mesh Node Issues (Eero, Google WiFi, Etc.)

Fix:

• Reboot the mesh system from the app if possible
• If not, power cycle the main unit first, then the nodes

Also check the app for:

• a node showing offline
• an internet outage alert
• firmware updates waiting

2.4GHz vs 5GHz Weirdness

Quick test:

• Connect the device to 2.4GHz (if you have separate network names)
• Then try 5GHz
• See if one works consistently

If one band is flaky, it can be interference, router settings, or a device driver issue.

Things To Avoid So You Don’t Make It Worse

Factory Resetting Too Early

A factory reset is the “nuke it from orbit” option.

Sometimes it’s necessary, but doing it early often creates extra problems:

• you lose the WiFi name and password
• you lose any ISP login settings
• you lose port forwards, device reservations, mesh configs, parental controls
• and you still might not fix the real issue (like an NBN outage)

Leave factory reset until you’ve confirmed the basics: outage checks, lights, power cycle, and whether it’s one device or all devices.

Changing Random Settings Without Knowing The Cause

People jump into DNS, WiFi channels, security settings, and “advanced” router options when the issue was just a dropped modem link or a device with a stuck VPN.

If you change too many things at once, you lose the trail.

When To Call Your ISP vs When To Call A Technician

What The ISP Can Fix

Call your ISP if:

• All devices are down and the modem/NBN box looks offline
• You suspect an outage or a line issue
• The internet/WAN light never comes good after a proper power cycle
• You’ve got constant dropouts (not just one random device)

What A Jim’s IT Tech Can Actually Sort Out (Quickly)

A technician is usually the better option when:

• It’s only one device and you want it fixed properly
• You’ve got a router that’s half-working (WiFi connects, internet is inconsistent)
• DNS, DHCP, extenders, mesh nodes, or “smart” settings are causing weird behaviour
• You want the network set up properly so it stops happening (good WiFi placement, clean config, firmware updates, proper security)

A Jim’s IT tech can also tell you quickly if the router is dying, or if it’s something simple like a cable, a setting, or a device issue.

A Final Word

When WiFi says “connected but no internet”, the trick is separating the problem into the right bucket: all devices or one device. Once you do that, the fix usually becomes obvious, and you can stop guessing.

If it’s an outage or the modem isn’t online, it’s an ISP problem. If the internet works on other devices, it’s almost always a device setting, VPN, DNS, or a stuck network profile.

Frequently Asked Questions

What does it mean when WiFi says connected but no internet?

It means your device is connected to the router over WiFi, but the router (or your device) can’t reach the internet.

Why is my WiFi connected but no internet on only one device?

Usually a bad saved WiFi profile, VPN/Private DNS, a weird IP address, or a captive portal that hasn’t been accepted yet.

Why is my WiFi connected but no internet on all devices?

Often an ISP/NBN outage, the modem has dropped connection, DNS issues at the router, or DHCP problems.

How do I fix WiFi connected but no internet on Windows 11?

Start with network troubleshooter, then try a network reset, and if needed run DNS and network stack reset commands.

Why does it say “Connected, secured” but no internet?

“Secured” just means the WiFi link is encrypted (password protected). It doesn’t guarantee the router has internet access.

Can DNS cause “no internet” even when WiFi is connected?

Yes. If DNS isn’t working, websites and apps may fail even though the WiFi connection itself is fine.

Why does hotel WiFi say connected but no internet?

Usually you need to open a browser and accept a login page (captive portal) before it lets you online.

Should I factory reset my router?

Not as a first step. Check outage, power cycle correctly, and test one device vs all devices first. Factory reset should be a last resort.
