On the Galaxy Z Fold5 the Wi-Fi complaint has two eras. Early on, owners on Samsung's forums described a Fold5 that dropped Wi-Fi repeatedly. More recently, Fold5 owners report Wi-Fi, Bluetooth and hotspot all disconnecting repeatedly with One UI 8.5, which one called an everyday struggle. The fix list is the Samsung one with a foldable twist: forget the network and rejoin, turn off Intelligent Wi-Fi's switch to mobile data, update the router, and install the newest patch. The foldable twist is that the Fold5 has two screens and two halves, so Wi-Fi performance can depend on how you hold it; a metal case or a fold-out stand over the antenna band and a half-folded posture are worth testing.
If Wi-Fi, Bluetooth and hotspot fail together, the cause is the update, not the router.

Before you touch a setting
Record this first — changing settings destroys the evidence
- The router make and model and band
- Whether Bluetooth and the hotspot also drop
- Whether the fault began with One UI 8.5
- Whether it differs folded and unfolded

Model-specific
What is true of this model and not of its siblings
- A foldable's radios
- The Fold5 has antennas in both halves and the hinge, so a fold-out stand or a metal case can matter.
- What owners report
- Repeated disconnections of Wi-Fi, Bluetooth and the hotspot together after One UI 8.5.
- Why a foldable is different
- The Fold5 has antennas in both halves and around the hinge, and the cover screen and inner screen change how it is held; a case that wraps the hinge and a metal stand can both reduce signal.
- Report with detail
- Samsung's moderators ask for the router model, the One UI version and the time of each drop; a short log in Samsung Members is more useful than a general complaint.
Stop boundary
When this stops being a self-service repair
- !If Wi-Fi, Bluetooth and hotspot keep failing after the newest patch, send a Samsung Members error report
- !If the Fold5 fails on every network in Safe mode, book service
- !If only one router fails, update it

Exact questions
Common questions
Why does my Galaxy Z Fold5 keep dropping Wi-Fi?+
Owners report drops with One UI 8.5 and earlier; Intelligent Wi-Fi, the router and the update are the usual factors.
Do Bluetooth and the hotspot also drop on One UI 8.5?+
Fold5 owners describe all three dropping repeatedly after the update.
Does folding the phone affect Wi-Fi?+
It can change antenna exposure; test unfolded.
Is the Fold5 still updated?+
Yes, it runs current One UI releases, so the newest patch is the first fix.
Will a Fold5 case affect Wi-Fi?+
A thick or metal case can reduce range; test without it.
Why do Bluetooth and Wi-Fi drop together?+
When both fail at once, a software or radio-state fault is likelier than two separate problems; the newest patch is the first fix.
