How to connect, and the 2-hour limit
The free Wi-Fi at Stansted airport gives you 2 hours of access, and connecting takes seconds. Open the Wi-Fi list on your phone, tablet or laptop, pick the airport network, and accept the terms on the sign-in page that opens. There is no password and no charge. That is the whole process: the airport's own advice is simply to connect to the network.
One honest caveat. The airport does not publish the exact name of its network anywhere on its website, and the names quoted by third-party sites disagree with each other, so do not trust a specific network name you have read in advance. Look at the actual Wi-Fi list when you arrive and pick the airport's own network, or check the signs in the terminal. As with most airport networks, each device you use connects separately, and when the free time is up the connection drops, which the options further down cover.
Coverage, speed and the official silence
The free Wi-Fi runs across the terminal, so you can use it at check-in, in the departures lounge after security, and while you wait at the gate. It is fine for the things most people need at an airport: checking a boarding pass, messaging, email, looking up a gate or a train, and light browsing. For heavy use, such as an HD video call or a large upload, public airport Wi-Fi anywhere is a gamble at a busy time, and traveller reviews of the Stansted network often mention slow speeds or trouble connecting in the morning crush, so do not rely on it for anything that cannot drop out.
The airport's Wi-Fi page is deliberately brief, and that is worth knowing. It does not publish a connection speed, a paid faster tier, or a longer free allowance, so claims you see elsewhere are not the airport speaking. Some sites quote 4 hours free, a specific network name, or a paid unlimited option at anything from £1 to £9: none of that is on the official page, and the figures contradict each other. The airport commits only to 2 hours free. If that ever changes, it will show on the airport's own Wi-Fi page first, so that is the place to check rather than an aggregator.
When the free 2 hours runs out
Two hours covers most short waits, but the Stansted crowd often faces a longer one, whether that is a pre-dawn arrival for an 06:00 flight or a delay. When the free session ends, you have three sensible options.
The simplest is your own mobile data. If you are on a UK or EU contract with inclusive roaming, your phone's signal in the terminal is usually steadier than the shared Wi-Fi anyway, and tethering a laptop to it sidesteps the time limit entirely. For visitors from further afield, an eSIM bought before you fly does the same job. The second option is the airport lounge, which runs its own Wi-Fi as part of the entry price, faster and less crowded than the public network, which can be worth it on a long wait. The third is simply a seat in a cafe or bar, where there is no clock on your connection and you can charge a phone while you wait.
Staying safe and charged
Public Wi-Fi is fine for everyday use if you take the same care you would on any open network. Stick to sites showing the padlock, or HTTPS, in the address bar, which covers banking and shopping, because the encryption runs between your browser and the site rather than the airport network. For sustained or sensitive work a VPN adds a useful layer, and for anything you are unsure about, your own mobile data is safer than a shared network. Avoid entering card details or passwords on any page that is not secure, and if a sign-in page asks for an email, a secondary address keeps your main inbox off the marketing list.
Charging is the other half of staying connected. The terminal has power points around the seating, so you can keep a device topped up while you use the Wi-Fi, which matters most on an early start. For everything else in the building, the airport services hub has the shops, food and facilities, and the departures board has your gate and boarding time.
