Tips
When Heathrow Wi-Fi won’t play along
From Heathrow
If the landing page doesn’t open, Heathrow’s troubleshooting guide says to open a browser and go to www.heathrow.com, which should redirect you to it.
The guide lists the network as _ Heathrow Wi-Fi, with a leading underscore, so look for it near the top of the list.
On corporate laptops, the guide says the landing page can fail because of proxy settings. Turn off the proxy server setting, then reload www.heathrow.com.
If you use a VPN, the guide says you can turn the proxy setting back on once you are online.
The network is certified by Friendly WiFi and filters unsuitable content.
For help, Heathrow’s Wi-Fi page gives Customer Care on 0808 189 1365. The troubleshooting guide lists a 24/7 Wi-Fi line on 0330 6601130.
On a Mac
No sign-in page? Open http://captive.apple.com in Safari. A plain http page can be redirected to the airport’s sign-in page; an https one can’t.
Pause what hides it. A VPN, iCloud Private Relay or your own DNS can keep the page from opening. Turn them off, sign in, then turn them back on.
Forget and rejoin. A network the Mac already knows may not show the sign-in window again. Forget it in System Settings › Wi-Fi and join once more.
Look behind your windows. macOS opens the sign-in page in a small window of its own, which can open behind the others.
Kilobat is a Mac menu-bar app that shows what each app sends and holds back what can wait. At Heathrow:
It spots the sign-in page Free
When the page doesn’t open by itself, the menu bar says This Wi-Fi wants you to sign in, with Open sign-in page. When a sign-in runs out, it says Logged out by the Wi-Fi’s sign-in page instead of blaming DNS.
It warns you before time runs out Pro
Kilobat learns how long sign-ins last on each network, and warns you about five minutes before the next logout. While you’re signed in, the menu shows the time left.
It holds back what can wait Pro
Airport Wi-Fi is shared by a terminal full of people. Switch to the Travel profile and only the apps you allowed connect. Mark the network Metered and Kilobat switches to Travel by itself.
It checks the line before a call Free
The stutter test pings the internet every 50 ms for 20 seconds and shows the spikes an average hides. Check before meetings warns you five minutes before a call if something would freeze it; with Pro, one button pauses the culprits.
Yes. Heathrow says free Wi-Fi is available throughout its terminals. You join Heathrow Wi-Fi and register.
Is there a time limit on Heathrow Wi-Fi?
Heathrow doesn’t publish one. Its page says the Wi-Fi is free to use during your time at the airport.
What if the Heathrow Wi-Fi page doesn’t load?
Go to www.heathrow.com in a browser to reach the landing page. On work laptops, turn off the proxy setting first.
What is the Heathrow Wi-Fi network called?
Heathrow names it Heathrow Wi-Fi. Join it, then sign in on the page that opens.
Why won’t the Heathrow Wi-Fi sign-in page open on my Mac?
A VPN, iCloud Private Relay or your own DNS can keep it from opening. Turn them off, open http://captive.apple.com in Safari, and turn them on again once you’re signed in. Kilobat shows Open sign-in page when a network is waiting for you.
