WiFi Connected But No Internet on Windows 11 (Fix)
Short answer: Run ipconfig and check your WiFi adapter's IPv4 address. If it starts with 169.254, the router never gave you an address — restart the router, and if it persists the DHCP pool is full, so expand it or shorten the lease time. If you have a normal address but no internet, the cause is usually DNS: switch to 1.1.1.1, run ipconfig /flushdns, then netsh winsock reset.
Run ipconfig in Command Prompt. Look at your WiFi adapter’s IPv4 address. If it starts with 169.254, your computer never got an address from the router — DHCP failed and Windows assigned itself a fake one. Restart the router first. If 169.254 comes back, your router’s DHCP pool is probably full. Every phone, tablet, smart TV, Ring doorbell holds a lease, and most consumer routers default to 32 or 64 slots. I’ve seen families with 30+ devices genuinely run out. Log into the router at 192.168.1.1 and either expand the pool or drop the lease time to 2 hours so abandoned devices stop hogging addresses.
If your IP looks normal — 192.168.x.x — then the connection itself is fine and something else is blocking traffic. Open Command Prompt as admin and run: ipconfig /release, ipconfig /flushdns, ipconfig /renew, netsh winsock reset. Restart. Fixes maybe 40% of these cases because the usual culprit is a stale DNS cache or corrupted Winsock catalog. If those individual commands don’t cut it, a full network reset through Settings reinstalls the adapter drivers too.
A woman brought in her Surface last month. WiFi connected, full bars, no internet in any browser. I ran ipconfig — valid IP, valid gateway. Pinged 8.8.8.8, worked fine. So the connection was genuinely working at the network layer but every browser said no internet. She’d installed some free VPN months ago, uninstalled it, but it left a proxy configured in Windows — pointing at localhost:8888 which no longer existed. Every outbound HTTP request hit a dead proxy. She’d spent two days flushing DNS and resetting adapters because that’s what every guide says to do. Check yours at Settings, Network & Internet, Proxy.
DNS and Drivers
Change your DNS servers. ISP DNS goes down more often than you’d think, and when it does you have a valid connection but can’t resolve domain names — which looks exactly like “no internet” in a browser. Switch DNS to 1.1.1.1 and 8.8.8.8. I use Cloudflare primary and Google secondary on every machine I touch because ISP DNS is always the first thing to break.
Try disabling IPv6 too. Run ncpa.cpl, double-click WiFi, Properties, uncheck TCP/IPv6. Some routers claim IPv6 support but their implementation is broken — Windows tries the IPv6 path first, fails silently, marks the connection dead even though IPv4 works underneath. Not permanent, just eliminates one variable while you figure out the real cause.
If this started right after a Windows Update, the update probably swapped your WiFi driver for Microsoft’s generic version. Device Manager, Network adapters — if you see a vague name instead of your actual Intel or Realtek hardware, right-click, Update driver, Let me pick from a list, choose the OEM driver. Otherwise download it from your laptop manufacturer’s site. Don’t rely on Device Manager’s automatic search, it pulls from Microsoft’s catalog which is months behind.
Intel AX200 and AX210 adapters have a “Roaming Aggressiveness” setting in the Advanced tab that causes exactly this. Set too high, the adapter constantly scans for better access points and drops your current connection during each scan. Medium or Low fixes it. If your router broadcasts the same name on both 2.4GHz and 5GHz, the adapter bounces between bands — give them different SSIDs on the router or force 5GHz in the adapter settings.
The Weird Ones
Windows 11 randomizes your MAC address by default on some networks. Privacy feature, different hardware address each time you connect. Problem is some routers use MAC filtering or tie DHCP reservations to specific addresses, so a randomized MAC gets blocked or refused. Settings, Network & Internet, WiFi, click your network name, turn off random hardware addresses.
Hyper-V keeps catching me. If you’ve ever enabled it for Docker or WSL2, it creates a virtual network switch bound to your physical WiFi adapter. Sometimes the virtual switch hijacks the connection and the real adapter gets nothing. Hyper-V Manager, Virtual Switch Manager, delete external switches you’re not using. Developers enable Hyper-V once and forget it exists, then six months later can’t figure out why WiFi randomly drops.
For routing table junk left by old VPNs, corrupted TCP/IP registry, or adapter firmware problems — the stuff where flushing DNS does nothing — our network diagnostic reads the full routing and adapter stack remotely. If DNS specifically is failing or your problem is slow speed rather than no connectivity, those are different paths.
Frequently Asked Questions
Why does my WiFi say connected but no internet on Windows 11?
The most common cause is a stale DNS cache or corrupted Winsock catalog — Windows has a valid WiFi connection but the IP configuration underneath is broken. Running ipconfig /release, ipconfig /flushdns, ipconfig /renew, and netsh winsock reset fixes it about 40% of the time. Other causes include ISP DNS server outages, VPN proxy remnants, DHCP pool exhaustion, and WiFi driver issues after Windows updates.
How do I fix WiFi connected but no internet?
Open Command Prompt as admin and run four commands in order: ipconfig /release, ipconfig /flushdns, ipconfig /renew, netsh winsock reset. Restart your computer. If that doesn't work, check your IP address with ipconfig — if it starts with 169.254, your router's DHCP isn't assigning addresses and you need to restart the router or expand its DHCP pool.
Can a VPN cause WiFi connected but no internet?
Yes, even after uninstalling. VPNs often leave behind proxy configurations, TAP/TUN virtual network adapters, and routing table entries. Check Settings > Network & Internet > Proxy and make sure 'Use a proxy server' is toggled off. Also check Device Manager for leftover TAP-Windows or TUN adapters under Network adapters.
Why does Windows 11 MAC randomization break my WiFi?
Windows 11 randomizes your MAC address by default on some networks as a privacy feature. Some older routers, corporate networks, and captive portals use MAC filtering or tie DHCP reservations to specific MACs. Your computer presents a new MAC, the router doesn't recognize it, and blocks the connection. Go to Settings > Network & Internet > WiFi > your network > Random hardware addresses and turn it off.
