How to Fix AirDrop When It Refuses to Work, and Why It Does That

You are standing next to someone, both of you holding iPhones, both trying to send a single photo across about forty centimetres of air, and the little radar circle just spins. The other person’s name never appears. You both toggle Bluetooth off and on, mutter something unkind about Apple, and in the end you email the photo to each other like it is 2009. I have watched this exact scene play out at dinner tables, in two separate meeting rooms, and once at a wedding where the best man airdropped his speech to precisely nobody.

Here is the thing that makes AirDrop infuriating: when it works, it is the best feature on the phone, and when it doesn’t, it gives you nothing to grab onto. No error, no reason, just a name that won’t show up. But AirDrop isn’t magic and it isn’t random. It fails for a short list of concrete reasons, and once you understand the machinery underneath, the fixes stop being superstition and start being a checklist you can run in under a minute.

What AirDrop actually is, and why that explains everything

AirDrop is not one radio doing one job. It is three things happening in sequence, and any one of them breaking takes the whole feature down.

First, the two devices find each other over Bluetooth Low Energy — a quiet, low-power handshake that says “I exist and I’m willing to receive.” Then, the moment you accept, the actual file flies over a direct, device-to-device Wi-Fi link Apple calls AWDL (Awesome Wireless Direct Link, genuinely). That second part is the key to the single most common confusion in this whole subject: AirDrop needs Wi-Fi switched on even though it never touches your home network or any router. The two phones build their own private Wi-Fi bridge for the duration of the transfer and tear it down afterwards.

So the rule that solves most failures is blunt: both Bluetooth and Wi-Fi must be on, on both devices. Not connected to anything. Just on. If either person has Wi-Fi off to “save battery,” AirDrop is already dead before anyone presses share.

Start with the four switches

Before you touch anything clever, run these four checks. In my experience they fix three out of four AirDrop failures, and they take fifteen seconds.

1. Bluetooth on, both devices. Swipe into Control Centre and check the icon is lit, not greyed. The “off until tomorrow” toggle in Control Centre is not the same as fully off, but for AirDrop, lit is what you want.

2. Wi-Fi on, both devices. Same place. It does not need to be joined to a network — it needs the radio awake. This is the one nobody believes until they try it.

3. Personal Hotspot off. This is the sneaky one. If either phone is sharing its connection as a hotspot, it has commandeered the Wi-Fi radio for that job and has nothing left for AirDrop. Settings → Personal Hotspot → Allow Others to Join → off. I have lost a genuinely embarrassing amount of time to this exact setting.

4. Both devices awake and unlocked. A receiving iPhone that is face-down and locked will often not surface for discovery. Wake it, unlock it, and ideally have the share sheet or home screen showing.

Discoverability: the setting that makes you invisible on purpose

If the radios are all healthy and a device still won’t appear, the receiver is almost certainly set to be unfindable. On the device that is meant to receive, open Control Centre, press and hold the connectivity box (the cluster with Wi-Fi and Bluetooth), and tap AirDrop. You get three choices, and the differences matter more than people realise.

Setting	Who can see you	When to use it
Receiving Off	Nobody	Default for the paranoid; also the reason your friend “can’t see you”
Contacts Only	People whose Apple ID is in your Contacts	Day-to-day, but it is fussy — see below
Everyone for 10 Minutes	Anyone nearby, then it auto-reverts	The one to use when something just won’t connect

Contacts Only is where the quiet failures live. For it to work, three things all have to be true at once: both people are signed into iCloud, each has the other’s Apple ID email or phone number saved in a contact card, and those details exactly match the Apple ID in use. Miss any one of those and you stay invisible to each other with no explanation. When you are standing next to someone and just need the photo to move, stop fighting it and switch the receiver to Everyone for 10 Minutes. Apple added the ten-minute auto-revert precisely so you can do this without leaving yourself open forever.

The Mac-only gremlins

Sending between two iPhones is usually a radio or discoverability problem. The moment a Mac is involved, two extra suspects appear.

The firewall set to block everything. Open System Settings → Network → Firewall. A firewall that is simply on is fine — AirDrop still works. But if you have ever enabled Block all incoming connections, that switch does exactly what it says and quietly kills AirDrop along with a lot of other things. Turn that specific option off; you can leave the firewall itself on.

The Mac is asleep or the lid is shut. A MacBook with the lid closed is not going to receive anything. And in Finder, AirDrop discovery is most reliable when you actually have an AirDrop window open (in any Finder window’s sidebar, click AirDrop) — that window is what keeps the Mac broadcasting “I’m here” at full strength.

While we are on Macs: if AirDrop has never once worked on a particular machine and the menu seems oddly absent, check Settings → Screen Time → Content & Privacy Restrictions → Allowed Apps on iPhone, or the equivalent on Mac. AirDrop can be switched off entirely here, often by a parental-controls setup someone forgot about. If it is disabled there, no amount of radio-toggling will ever bring it back.

The symptom-to-fix table

When you have ten seconds and a specific behaviour, this is the lookup I actually use.

What you’re seeing	Most likely cause	The fix
Their name never appears	Wi-Fi off, or receiver on Contacts Only / Off	Both radios on; set receiver to Everyone for 10 Minutes
Connects then “Failed”	AWDL link dropped, or moved too far apart	Stay within ~9 metres; reset radios and retry
Stuck on “Waiting…” forever	Personal Hotspot is on somewhere	Turn Hotspot off on both devices
Works one way but not the other	One device locked, asleep, or firewalled	Wake and unlock it; on Mac, uncheck Block all incoming
AirDrop missing entirely	Screen Time restriction	Allow AirDrop in Content & Privacy Restrictions

When nothing works: reset the radios properly

If you have been through all of the above and a transfer still hangs, the problem is almost always that the AWDL link — that private Wi-Fi bridge — has got itself wedged. You don’t need to wipe anything. You need to make the radios start fresh.

The fast version: toggle Airplane Mode on, wait five seconds, then off, on both devices. That forces Bluetooth and Wi-Fi to re-establish from scratch and clears a stuck AWDL state about half the time. If that doesn’t do it, restart both devices — a genuine restart, not a lock. AWDL runs as a background service, and like any service it occasionally needs to be kicked. I keep meeting people who treat “have you tried restarting it” as a cliché to be ashamed of, but for this specific feature it is the single most effective move once the obvious switches are ruled out.

For genuinely large transfers — a 4K video, a folder of RAW photos — also just stand closer. AWDL’s throughput falls off a cliff with distance and walls, and “it failed at 80%” is very often “you wandered into the next room.” A direct cable between two devices will always beat a flaky AirDrop for moving tens of gigabytes, and it never cares about discoverability.

The honest takeaway

AirDrop’s reputation for flakiness is mostly undeserved — it is not unreliable so much as unexplained, and an unexplained failure feels like a broken one. Almost every time it lets you down, the cause is one of five mundane things: a radio switched off, a hotspot hogging Wi-Fi, a discoverability setting hiding you, a locked-and-asleep receiver, or a stuck AWDL link that a restart clears. Learn that short list once and the spinning radar circle stops being a mystery and becomes a thirty-second diagnosis. The feature was never the problem. It was just never telling you what it needed, and now you know: both radios on, both phones awake, set to Everyone, standing close. Do that and AirDrop goes back to being the quiet little miracle it is supposed to be.
