Hotel, airport, cafe, library and train Wi-Fi usually makes you accept terms or enter a room number on a login page (a "captive portal") before it lets you online. Normally your device opens that page by itself. When it doesn't, you're stuck with "Connected, no internet" or, on Windows, "No internet, open".
Here is how to bring the page up, from the quickest trick to the settings that most often block it.
The login page appears when the network intercepts a web request. Secure (HTTPS) sites can't be intercepted, so your usual homepage may just show an error instead. Open a new browser tab and type one of these addresses exactly:
http://neverssl.com - a site made for this job; it never uses HTTPS.http://www.msftconnecttest.com/redirect - the address Windows uses to trigger the login page.http://captive.apple.com - the address Apple devices use.If the network is waiting for you to sign in, the login page should replace the site. Accept the terms or enter the details the venue gave you.
A VPN tries to send all traffic through its own servers, which the portal blocks, so the login page never reaches you. Disconnect or pause the VPN, sign in on the portal, then reconnect the VPN. Some VPN apps have a setting that allows "captive portal" or "local network" access for exactly this.
Many portals work by answering your device's DNS lookups themselves. If you set a public DNS server (such as 1.1.1.1 or 8.8.8.8), or use encrypted DNS, those lookups skip the venue and the page never appears.
Put your preferred settings back once you're online.
Forgetting the network clears a stale login state.
Then connect again and try Fix 1 straight away.
A browser can keep showing a cached or secure version of a site and never let the redirect through. Open a private/incognito window, or another browser, and try http://neverssl.com again. Temporarily disabling ad or script blockers can also help, because some portals rely on scripts or pop-ups.
Phones and laptops can use a private hardware (MAC) address for each network. That's good for privacy, but a portal that remembers devices by address may ask you to log in repeatedly, or get confused if the address changes mid-session.
Change this only for the public network, not your home one, if privacy matters to you.
Turn Wi-Fi off, wait ten seconds and turn it on again, or restart the device. Then join and try Fix 1 once more.
Sometimes the portal itself is down or has hit its device limit. Signs: other guests have the same problem, or the page says your session or device count has expired. Ask the front desk or staff; they can reset it or give you a new code. Your phone's own mobile data or hotspot is a good fallback in the meantime.
If you're at home rather than on public Wi-Fi and see "No internet", this page isn't the issue: go to our Wi-Fi connected but no internet guide, or DNS server not responding if the troubleshooter mentions DNS.
'Open' means the Wi-Fi network has no password. 'No internet' usually means you haven't signed in on its login page yet, so the network is blocking internet access until you do.
The page only appears when your device's connection test is redirected. A VPN, custom DNS, Private DNS, or a browser that remembers a secure website can stop that redirect.
Websites that use HTTPS are encrypted even on open Wi-Fi. Avoid entering passwords on sites that don't show a padlock, and turn your VPN back on after the login page is done if you use one.
Many portals remember your device by its hardware (MAC) address. If your device uses a changing private address for that network, the portal sees it as a new device. Setting the private address to fixed for that network helps.
