The Wi-Fi Icon Has an Exclamation Mark on Windows: What It Means
What that warning next to the Wi-Fi icon means and how to fix it step by step.
This symbol means something very specific: your PC is connected to the Wi-Fi network, but that network has no internet access. This is different from not being able to connect at all — here the local connection works, what's missing is the next step.
Quick check: is it your PC or the network?
Try another device on the same Wi-Fi network. If it doesn't have internet either, the problem is with the router or your provider, not your PC — in that case, restarting the router is usually enough.
The real technical diagnosis
Command Prompt:
ipconfig
Look at your IPv4 address. If it starts with 169.254,
that is the exact cause: your PC failed to get a valid address from
the router.
An IP starting with 169.254 is an "emergency" address that Windows assigns itself when it fails to communicate with the router to get a real IP — it is the clearest, most specific sign of exactly what is failing.
Fix if your IP starts with 169.254
- Turn Wi-Fi off and back on.
- If that's not enough, forget the network and reconnect (Settings → Wi-Fi → "Manage known networks" → "Forget").
- If it's still the same, restart the router.
If your IP is normal but there's still no internet
The problem may be with DNS. Check whether you can ping your DNS server:
ipconfig /all | findstr /c:"DNS Servers"
ping [the address that appears]
If the ping fails, try manually changing the DNS to a known public
one, like 8.8.8.8 (Google), from the network adapter's
properties.
Tip: this exclamation mark, with no further
diagnosis, doesn't tell you whether the problem is IP or DNS — that
is why the ipconfig command is the real first step, not
just another basic check.
Frequently asked questions
What exactly does an IP starting with 169.254 mean?
It is an address Windows assigns itself when it fails to get a real IP from your router — it indicates a communication failure at the very first stage of the connection, before even reaching the internet.
Is this the same as not being able to connect to the Wi-Fi at all?
No, they are different problems. Here the connection to the local network does work (that's why you see 'connected'), but that network has no internet access. If you can't connect to the network at all, that is an earlier problem.
Does changing the DNS affect my privacy?
Switching to a well-known public DNS (like Google's or similar) is a common, safe practice for fixing connection problems — it carries no greater risk than using your provider's default DNS.
