"No internet, secured" on Wi-Fi — How to fix Windows 11

"No internet, secured" means Windows connected to the Wi-Fi but couldn't reach the internet. The router is fine — almost always it's a stale DHCP lease, broken DNS, or a corrupted TCP/IP stack.

Symptoms

▸Wi-Fi icon shows "No internet, secured"
▸Browser pages fail with 'connection failed'
▸Other devices on the same Wi-Fi work fine

Likely causes

▸Stale DHCP lease / IP conflict
▸DNS server unreachable or wrong
▸Corrupted Winsock / TCP/IP stack
▸VPN client left a broken adapter active

How to fix it — step by step

01
Forget and reconnect to the Wi-Fi
Settings → Network & internet → Wi-Fi → Manage known networks → click your SSID → Forget. Reconnect with the password.

Renew the IP address

Open elevated PowerShell:

ipconfig /release
ipconfig /renew
ipconfig /flushdns

03
Reset Winsock and the TCP/IP stack
```
netsh winsock reset
netsh int ip reset
```
04
Set DNS to Cloudflare or Google
Settings → Network → your adapter → DNS server assignment → Manual → IPv4: 1.1.1.1 and 1.0.0.1. Reboot.
05
Reset the network stack
Settings → Network & internet → Advanced network settings → Network reset → Reset now. Reboot — this is the nuclear option but works after everything else.
