How to Fix Galaxy S24 Wi‑Fi Keeps Dropping

By Rob · Editor, Tech Problem Solved

This guide is a practical, ordered fix for Wi‑Fi Keeps Dropping on Galaxy S24 running Android. Start with the least destructive checks, then software repairs, and only then a backup-and-reset. Each numbered step includes a simple diagram so you can match what you see on screen.

Who this guide is for

• Primary device: Galaxy S24
• Software family: Android
• Brand: Samsung
• Nearby models in the same brand/OS generation usually follow the same order of checks.

Editor notes before you start

• This guide is written for Galaxy S24 on Android. Sister Samsung models are often similar, but menu labels can move after an update — use Settings search when a path differs.
• If other devices on the same router stay online, focus on Galaxy S24’s Wi‑Fi profile (forget/rejoin, Private Wi‑Fi Address, VPN) before factory-resetting the phone.
• We keep these guides intentionally focused: fewer pages, clearer steps, and honest stop-points before unsafe hardware work.

What you will need

• 10–15 minutes without rushing
• Your device passcode / password
• Your Wi‑Fi name and password
• Access to the router (and modem if separate)

Before you start

• Save any open work on Galaxy S24 if the device is still responsive.
• If you have not backed up recently, start a quick cloud backup before deeper resets.
• Work through the steps in order; skip ahead only if a step clearly does not apply.

Symptoms

• Wi‑Fi connects, then drops every few minutes without moving rooms.
• Other phones or laptops on the same router stay online.
• You may see “Connected, no internet” or repeated password prompts.

Common causes

• Saved network with wrong password or MAC randomisation conflicts
• Aggressive Wi‑Fi sleeping in battery settings
• APN / mobile data misconfigured after a SIM change
• Router band or channel congestion
• VPN or private DNS breaking connectivity

Step-by-step fix

1

Toggle and rejoin Wi‑Fi cleanly

Turn Wi‑Fi off for 10 seconds, then on. Forget the SSID and rejoin via Settings → Network & internet → Internet with the correct password. Prefer 5 GHz when you are close to the router; use 2.4 GHz through thick walls.

2

Power-cycle the network path

Restart Galaxy S24. Unplug the modem (if separate) for 2 minutes, power it on, wait until sync lights settle, then power the router, wait 2 minutes, then reconnect Galaxy S24.

3

Install available updates

Install updates from Settings → System → System update. Stay on power/Wi‑Fi until the process finishes.

4

Reset network settings (keeps photos and apps)

Use Reset Wi‑Fi, mobile & Bluetooth from Reset options. Rejoin networks afterwards.

5

Deeper isolation before erase

Test in safe/guest mode if available, or with a second user profile. Decide whether the fault is hardware-like (always) or software-like (after updates). Keep a short note of Settings changes so you can undo them.

6

Last resort: backup then reset

Back up first. Use Settings → System → Reset options only if earlier steps failed. Set up Galaxy S24 cleanly, confirm the fix, then bring data back in stages.

What success looks like

Galaxy S24 stays connected through a web page load and a short video stream without dropping.

Prevention tips

• Reboot the router monthly and after ISP engineer visits.
• Keep a written note of the admin password somewhere safe offline.
• Stop DIY if you smell burning, see liquid damage indicators, or the chassis is swollen.

When to get professional help

Stop DIY if you smell burning, see liquid damage, notice a swollen battery, or if Galaxy S24 still fails after a clean backup-and-reset. Physical damage and board-level faults need professional service.
