Samsung Galaxy Z Fold6 and Fold5 family will not connect to Wi-Fi or keeps disconnecting

Samsung Galaxy Z Fold6 and Fold5 family will not connect to Wi-Fi or keeps disconnecting: one network, all networks, VPN/profile and radio hardware produce different fixes. Scoped to SM-F956*, SM-F946*.

On a Galaxy Z Fold6, Wi-Fi that drops or will not load pages should be tested against the router first, then the phone. Turn Wi-Fi off and on, restart, then go to Settings, Connections, Wi-Fi, tap the gear beside the network and choose Forget. Check the same menu for Switch to mobile data, which moves the phone to mobile data when Wi-Fi is weak and can look like random drops. One UI also offers Auto reconnect and a Wi-Fi power-saving behavior. The Fold6 supports Wi-Fi 7, so a mixed-mode router can cause trouble; try the router's Wi-Fi 6 mode. If the phone cannot find any network, update the software and reset the network settings under General management, Reset.

Model-specific

What is true of this model and not of its siblings

Wi-Fi
Samsung lists Wi-Fi 7 on the Galaxy Z Fold6.
Antennas
The antennas sit in the frame, so keep it uncovered for the best signal.
Updates
Samsung's recent foldables receive several years of One UI updates, which include Wi-Fi fixes, so keep the software current.
Which screen is the Wi-Fi on
The Fold6 has an inner screen and a cover screen, but one Wi-Fi radio. If the connection drops when you fold or unfold the phone, check whether the app restarts at the same moment, since the app, not the radio, may be reloading. Forget the network and rejoin on the inner screen, then test by folding.
Router settings that suit a foldable
A router set to Wi-Fi 7 only or to very wide channels can trouble phones that handle those features unevenly. Use mixed mode, an 80 megahertz channel on 5 GHz and a separate name for the 2.4 GHz band if the phone struggles at a distance. Keep the router in the open, and update both the phone and the router before a reset.

Exact questions

Common questions

Does the Galaxy Z Fold6 support Wi-Fi 7?+

Yes, the Fold6 supports Wi-Fi 7, so the router's mode may matter.

Why does my Fold6 switch to mobile data?+

The Switch to mobile data option moves the phone when Wi-Fi is weak. Turn it off if you prefer to stay on Wi-Fi.

Does folding the phone affect Wi-Fi?+

It should not, but the antennas are in the frame, so a case or a hand covering the edge can reduce the signal.

Will resetting network settings erase my data?+

No, it removes saved networks, Bluetooth pairings and VPNs, not your files or apps.

Which screen should I use to check the Fold6's connection?+

The Wi-Fi settings are the same on the cover and inner screens, so you can check signal and the saved networks from either, but unfold the phone before a reset to avoid a restart in the middle of the process.

Why is Wi-Fi slow on my Fold6 only when it is folded?+

A hand or a case covering the frame edge can reduce the signal, and the cover screen apps may run differently. Compare speed unfolded and with the case off.

Should I use the 2.4 GHz or 5 GHz band on the Fold6?+

Use 5 GHz for speed at close range and 2.4 GHz for distance. If the router combines them under one name, give them separate names to choose.

Why does Wi-Fi drop when I fold the Fold6?+

The app may reload; the radio is the same for both screens.

What router mode helps the Fold6?+

Mixed mode with an 80 megahertz channel.
