How to Forget a Hotel Wi-Fi Network After Your Trip

Two weeks after the trip, your phone still hops onto the airport lounge network the moment you walk past the terminal, and the laptop quietly rejoins the hotel SSID when you open it in a cafe across town. Forgetting that entry is a per-device setting, and it removes the saved Wi-Fi profile on that one device only. It is not a sign-out from the venue's captive portal account, not a VPN logout, and not the removal of a company configuration profile. The checks below go in order, so stop at the first one that does not match what the device shows you.

Check which device is actually rejoining

Start with the notification, not with the list. The device that showed a connected banner is the one holding the profile, and a household with three phones rarely has identical saved networks on all of them. Open Wi-Fi settings on that device alone and look for the venue name among the saved or known networks.

If the entry is there but the device has not joined in weeks, you are dealing with auto-join rather than a stale password. Both cases end at the same removal step, though only the second needs the auto-join toggle checked afterwards.

Forget it on the phone first

On iOS 16 and later, open Settings, tap Wi-Fi, then Edit in the corner of the network list, select the venue entry and delete it. On older releases the same control sits behind the info button next to each network, labelled Forget This Network. Apple documents both paths in its guide to forgetting a Wi-Fi network, which is worth opening if your screen matches neither description.

Android labels vary by vendor skin, but the shape is stable: Settings, Network and internet, Internet, then Saved networks on Android 12 and later, where the venue entry offers Forget. Samsung and Xiaomi builds may fold that list into Connections or straight into Wi-Fi.

Either way, the removal drops the stored passphrase for that SSID along with the per-network options you had set for it.

Then clear the laptop profile

Windows keeps a separate WLAN profile per SSID, and it survives a disconnect in a way that catching yourself before the join does not. In Windows 11 the entry lives under Settings, Network and internet, Wi-Fi, Manage known networks, with a Forget button beside each name. The terminal is quicker: netsh wlan delete profile name="Terminal_Free_WiFi" reports whether the profile was removed. Disabling the adapter is a different step: the radio keeps working, and the next SSID you pick is stored as a fresh profile.

On macOS, open System Settings, Wi-Fi, then Details beside the current network; the Known Networks list carries a minus button. Older releases keep that list behind Advanced. The shell equivalent is networksetup -removepreferredwirelessnetwork en0 "Terminal_Free_WiFi", with en0 taken from networksetup -listallhardwareports when your Mac uses something else.

Removing a laptop profile also discards the per-network proxy, 802.1X and DNS settings attached to it, so confirm the SSID is the travel one before you agree.

Stop if the profile belongs to someone else

A managed device may show the network as installed by your organisation, with the Forget button missing or greyed out. That is a configuration payload, not a user setting, and a manual removal either fails or returns at the next management check-in. Ask the IT desk to retire the payload rather than deleting the management profile or the root certificate that arrived with it. A managed entry in that list is a symptom to report, not something the user is meant to fix locally.

The same caution covers 802.1X networks that authenticate with a client certificate. Forgetting the SSID leaves the certificate in place, so a retired shared laptop needs that credential revoked, not just the network entry deleted.

If your VPN client keeps a trusted-network or on-demand rule naming the SSID, note it now. Deleting the Wi-Fi entry does not edit that rule, and a rule aimed at a network that no longer exists may never fire again.

Confirm the entry stays gone

Toggle Wi-Fi off and back on, or reboot, then reopen the saved list. A network that reappears within a minute is being reinstalled by something: a management profile, a sync service, or a second account on the same machine.

On Apple hardware, saved Wi-Fi passwords travel between your own devices through iCloud Keychain, so forgetting the network on the phone does not clear the entry on a Mac signed into the same account. Check each device separately instead of assuming one removal covered the household.

Expect one more portal login. iOS and Android present a randomised MAC address per network, so after a forget and rejoin the venue sees a new client and usually asks for the room number or email again.

Finish in the VPN client: open any list of trusted or excluded networks, delete the travel SSID if it is still named there, then connect once and confirm the tunnel comes up on the network you actually use at home.
