Wi-Fi Says “Connected, No Internet” After a Router Reboot? Diagnose It in 3 Checks

Your device can reconnect to Wi-Fi while the router is still waiting for its internet connection to return. The Wi-Fi connection only confirms that your device can reach the router; it does not prove that the router can reach your internet provider.

Before changing router settings, find out whether the problem affects one device, every device, or only certain websites. That simple comparison determines what to check next.

Start with this three-check diagnosis

What you find	Where to look next
Only one phone or computer has no internet	That device’s saved Wi-Fi connection, IP settings, VPN, or DNS
Every device on Wi-Fi has no internet	The router’s internet connection, modem or fiber ONT, or ISP
Some websites or apps work, but others do not	DNS, a VPN, proxy, security filter, or the affected service

Test another device on the same Wi-Fi. If it works, focus on the device showing the error. If it also fails, continue with the router and internet connection.
Check the router’s internet or WAN status light. A working Wi-Fi indicator does not necessarily mean the internet connection is back. Check the router’s app or status page too, if you use one.
Try one test over Ethernet, if available. If a wired computer can reach the internet but Wi-Fi devices cannot, the problem is likely on the wireless side. If both wired and wireless devices fail, check the modem/ONT, router WAN status, and ISP connection.

If every device lost internet after the reboot

Check the modem or fiber ONT first. Its connection to your provider may take longer to recover than the router’s Wi-Fi signal. Look for the status indicators described in the equipment manual or check your provider’s app for a known outage.

If the modem or ONT still appears offline, or its internet indicator never settles, contact your ISP. Restarting the router repeatedly will not fix a provider outage or a modem that has not reconnected.

If there is no outage and the equipment appears powered normally, restart the modem and router once using the manufacturer’s instructions. For separate devices, a typical sequence is:

Unplug the router and modem from power.
Wait at least 30 seconds.
Reconnect the modem and wait for its connection indicators to settle.
Reconnect the router and give it a few minutes to start.
Test a phone or computer again.

If you have a combined modem-router, treat it as one device. Do not press the recessed factory-reset button: a factory reset can erase Wi-Fi settings and, on some equipment, settings needed to connect to your ISP.

If only one device says “No Internet”

First turn Wi-Fi off and back on on that device, then reconnect to your home network. If it still fails, forget the network and join it again, making sure you have the correct password. This removes that device’s saved connection profile; it does not reset the router or affect other devices.

On a Windows computer, open the network troubleshooter. If the issue continues, open Command Prompt and run:

ipconfig /all

Look for the wireless adapter’s IPv4 address, default gateway, and DNS server. An address beginning with 169.254 can mean Windows did not obtain an IP address from the router. If the computer is set to obtain its address automatically, you can try renewing its connection:

ipconfig /release
ipconfig /renew

These commands apply to Windows. On a phone, tablet, Mac, or other device, use that device’s network settings or built-in troubleshooting steps instead.

If the device has a valid network connection but still cannot load websites, temporarily turn off a VPN or manual proxy if you use one, then test again. If only website names fail while other network functions work, DNS may be involved. On Windows, you can clear the local DNS cache with:

ipconfig /flushdns

Do not change your router’s DNS settings as the first step. First confirm whether the issue is limited to one device and whether the router itself is online.

What the results tell you

Other devices work normally: the internet connection is probably available; investigate the affected device’s saved Wi-Fi profile, VPN, proxy, or IP configuration.
No device can get online, including over Ethernet: check the modem/ONT and router’s WAN status, then ask your ISP to check the line if their equipment does not reconnect.
Ethernet works but Wi-Fi does not: restart the router once, then check its wireless settings and manufacturer guidance. Avoid changing several settings at once, so you can tell which change helped.
Only some websites fail: test another browser or app and temporarily disable a VPN, proxy, or security filter. The problem may be limited to DNS or a particular service rather than the Wi-Fi connection itself.

When to check DHCP settings

DHCP is the service that assigns local IP addresses to devices. It is worth investigating when a device cannot obtain a usable address, when the router’s status page shows an address-assignment error, or when you have more than one router distributing network addresses.

Most home networks should have one device acting as the DHCP server. If you recently added a second router, changed the network layout, or enabled router mode on a mesh system, check the manufacturers’ instructions before changing DHCP settings. A duplicate DHCP server can give devices the wrong network information.

A DHCP issue is only one possible explanation for “Connected, no internet.” If all devices are affected, check the router-to-modem connection first. If only one device is affected, troubleshoot that device before changing settings for the entire home.

When to contact your ISP or router maker

Contact your ISP if the modem/ONT does not regain its connection, the router reports that its internet/WAN connection is down, or every device remains offline after a single restart. Tell them whether the issue affects wired devices too and describe the modem’s status lights.

Contact the router maker if the modem is online but the router repeatedly fails to provide internet to wired and wireless devices. If only one computer or phone is affected, contact that device’s support service after trying its built-in network troubleshooting.

Frequently asked questions

Why does Wi-Fi say connected if the internet is down?

Your device can be connected to the router’s local Wi-Fi while the router has no working connection to your internet provider. The two connections are related, but they are not the same.

Does “Connected, no internet” mean DHCP is broken?

No. DHCP is one possibility, especially if a device did not receive a usable IP address. A modem that has not reconnected, an ISP outage, DNS trouble, or a device-specific issue can produce a similar message.

Should I factory-reset the router?

Not as an initial fix. A factory reset can erase your Wi-Fi name, password, and other connection settings. Try one normal restart and the checks above before considering a reset.
