Samsung Galaxy S24 WiFi keeps dropping, random disconnects, WiFi 6E not staying connected — safe checks (router, phone settings, update rollback) before you reset anything

Technician avatar Technician
I understand how frustrating WiFi dropping can be on a newer phone like the Galaxy S24. When it starts after an update, there’s usually a clear reason — and we can find it without erasing your phone or changing anything drastic.

Trust moment: let’s focus on safe checks first, and you can stop at any point if something doesn’t feel right.

Quick start: did the WiFi dropping start right after a Samsung or Android update, or was it gradual? And does it happen on all WiFi networks or just your home router?
Customer
It started after the last update, about a week ago. It mostly happens on my home WiFi. At work or the coffee shop it seems okay. My router is pretty new, maybe six months old.

That timing — right after an update — is a big clue. And the fact that it’s mainly your home network (not everywhere) tells us it’s probably not a hardware fault with the phone. It’s usually one of three things: the update changed how your phone talks to your specific router, a WiFi setting got reset during the update, or the router and phone need a fresh handshake.

Before we do anything, let me ask: what’s the router model or brand (if you know it)? And does the phone show it’s “connected” but just keeps losing the internet, or does it fully disconnect from the WiFi name?
Customer
It’s a TP-Link router. And it’s weird — sometimes it says “connected” but nothing loads, and sometimes it just drops the WiFi completely and I have to reconnect manually.
Technician avatar Technician
That’s helpful. The “connected but nothing loads” part is often a WiFi handshake issue — the phone thinks it’s on the network, but data isn’t flowing. And the full disconnects suggest the phone and router aren’t staying in sync.

Here’s what I want to check, and it’s all safe: is your TP-Link router running on WiFi 6 (6E), or an older standard like WiFi 5? The Galaxy S24 supports WiFi 6E, and sometimes updates change how the phone handles newer standards.
Customer
It’s WiFi 6. I’m not sure about the 6E part. I don’t remember changing anything on the router, but I’m worried I’ll mess it up if I go into settings.
Technician avatar Technician
That’s a reasonable worry. Trust moment: I don’t want you diving into router admin panels either. We can handle this on the phone side first, which is much safer.

Here’s what often fixes this: a “WiFi handshake reset” — which means forgetting the network on your phone and reconnecting. It clears out any stale settings from before the update. To do this safely: go to your phone’s Settings > Connections > WiFi, tap and hold your home network name, and choose Forget. Then reconnect using your WiFi password. Does that sound okay to try?
Customer
Yes, I can do that. I’ll need to look up my WiFi password, but I have it written down. Should I do this now?
Technician avatar Technician
Yes, go ahead. It takes about two minutes. Once you’ve forgotten and reconnected, try loading a few websites or apps to see if the drops happen again. If it’s smooth for the next hour, that’s often a sign the handshake reset worked.

While you’re doing that, I want to mention one more thing: after the update, your phone might have reset some WiFi settings automatically. One common one is “WiFi scanning” or “WiFi optimization.” If it’s turned on, it can sometimes cause brief drops while the phone scans for better networks. We can check that next if the drops continue.
Customer
Okay, I forgot the network and reconnected. It’s been about 20 minutes and so far so good. No drops yet. Should I wait longer to be sure?
Technician avatar Technician
Good sign. Give it another 30 minutes or so — try using it like normal, streaming a video or checking email. The drops usually happen pretty quickly if they’re going to happen. If you make it through an hour without any disconnects, that’s a solid win and often means the handshake reset did the job.

If drops do come back, don’t worry — we have a few more safe steps. One thing I want to ask: did the phone get very hot during the update, or has it been warm since then?
Customer
Not that I noticed. The phone feels normal. It’s been about an hour now and still no drops. I’m cautiously optimistic. Is this usually the fix, or should I expect it to come back?
Technician avatar Technician
An hour is a really good sign. For most people, when WiFi dropping starts right after an update and a handshake reset fixes it, it stays fixed. The update probably reset your saved WiFi settings, and reconnecting let the phone and router “shake hands” properly again using the new software.

That said, if it does drop again in the next day or two, here are two things to know: first, check if there’s a newer update for your phone (sometimes Samsung releases a patch update that fixes WiFi issues). Second, if it comes back, we can look at WiFi optimization settings, which is still a safe phone-side change.
Customer
That makes sense. I’ll keep an eye on it. If it happens again, I know what to check. This is so much better than what I was reading online — some forums said I’d have to factory reset the whole phone.
Technician avatar Technician
I’m glad. A factory reset is a last resort, not a first step. Most WiFi dropping issues after an update come down to settings or a handshake mismatch, which is exactly what we just fixed. Factory reset should only come up if nothing else works and you’ve ruled out the router and other networks.

Trust moment: I don’t want you erasing your phone just because one thing isn’t working. A handshake reset is gentle, reversible, and often the real answer. Keep an eye on it over the next few days, and if something changes, you know where to start.

Quick answer: the accepted fix

Accepted first fix for Samsung Galaxy S24 WiFi dropping randomly after update (safe approach): 1) forget your home WiFi network on the phone (Settings > Connections > WiFi > tap and hold network > Forget), 2) reconnect using your WiFi password to create a fresh handshake, 3) test for drops over the next 1–2 hours of normal use, and 4) if drops return, check for a newer phone update (sometimes Samsung releases a WiFi patch) and disable WiFi optimization or WiFi scanning in Advanced settings if the issue persists. Do not factory reset the phone as a first step — handshake resets fix most post-update WiFi issues.


Why Samsung Galaxy S24 WiFi drops after an update (and why it’s usually fixable)

When WiFi dropping starts right after a Samsung or Android update, it’s almost always because the update reset your phone’s saved WiFi settings or changed how the phone negotiates with your router. The Galaxy S24 supports WiFi 6 and 6E, and sometimes an update changes the protocol or security handshake the phone uses. Your router doesn’t know about these changes, so the phone and router fail to stay synchronized — leading to brief disconnects, “connected but no internet” moments, or full drops where you have to manually reconnect. The good news is that this is rarely a hardware problem and usually doesn’t require a factory reset. A simple “handshake reset” (forgetting and reconnecting to the network) tells the phone and router to start fresh with the new software, and that fixes most cases.

What to check first (safe checks before changing router settings or updating firmware)

Start with the gentlest step: forget your home WiFi network on the phone and reconnect. This clears out any stale WiFi settings from before the update and lets the phone and router shake hands properly using the new software. Next, test for drops over the next hour or two by using the phone normally — streaming video, checking email, or browsing. If drops continue, check whether your phone has a newer update available (sometimes Samsung releases a patch update shortly after a major update to fix WiFi or connectivity issues). If the issue persists, you can safely disable WiFi optimization or WiFi scanning in your phone’s Advanced WiFi settings, which sometimes causes brief disconnects as the phone scans for better networks. Avoid changing router settings or factory resetting the phone at this stage — those are last resorts. For more WiFi troubleshooting topics, see Troubleshooting Guides and Mobile Troubleshooting.

Samsung Galaxy S24 WiFi dropping after update — calm, senior-friendly guidance

Focus on the phone-side fixes first: handshake reset, update check, and WiFi settings optimization.

If your Samsung Galaxy S24 WiFi keeps dropping randomly after an update, don’t assume the phone is broken or that you need a factory reset. Most of the time, the update changed how your phone talks to your router, and a simple handshake reset (forgetting and reconnecting to the network) fixes it. If that doesn’t work, check for a newer update — Samsung often releases patch updates to fix WiFi issues within days of a major update. Disabling WiFi optimization or WiFi scanning in Advanced settings is a safe next step if drops continue. Only change router settings or factory reset if you’ve ruled out these phone-side fixes and the problem happens on multiple networks.

If the issue continues


Getting Started Is Easy

Ask for help, 24/7

If Samsung Galaxy S24 WiFi dropping started after an update, begin with a handshake reset: forget your home WiFi and reconnect. This clears stale settings and usually fixes the issue without factory reset.

Expert will respond in minutes

Most WiFi dropping issues after an update come down to a phone-router handshake problem, not hardware failure. A handshake reset works in about 80% of cases where drops start right after an update.

Stop random WiFi drops

Once the handshake is reset and your phone reconnects to the network with fresh settings, WiFi stability usually returns. If drops do return, checking for a newer update or adjusting WiFi optimization settings often resolves it.

FAQ

Why did WiFi dropping start right after a Samsung update on my Galaxy S24?

Updates sometimes reset your phone’s saved WiFi settings or change how the phone negotiates with your router. The Galaxy S24 supports WiFi 6 and 6E, and a new update might use a different security handshake or protocol. Your router doesn’t automatically know about these changes, so the phone and router lose sync — causing drops, brief disconnects, or “connected but no internet” moments. A handshake reset (forgetting and reconnecting) usually fixes this because it tells the phone and router to start fresh with the new software.

Is WiFi dropping after an update a hardware problem with the Galaxy S24?

No, it’s almost always a software or settings issue, not hardware failure. If the phone works fine on other WiFi networks (work, coffee shop) but drops on your home network, it’s a phone-router compatibility issue, not a broken phone. Hardware problems usually affect WiFi on all networks, not just one. A handshake reset and update check will tell you if it’s a settings issue (the most common case).

Should I factory reset my Galaxy S24 if WiFi keeps dropping after an update?

No — factory reset should be a last resort, not a first step. Most WiFi dropping issues after an update are fixed by a handshake reset (forgetting and reconnecting), checking for a newer update, or disabling WiFi optimization. A factory reset erases all your data and settings, which is unnecessary for a WiFi issue. Only consider it if handshake resets, updates, and WiFi settings adjustments don’t work and the problem happens on multiple networks.

What’s the difference between “connected but no internet” and a full WiFi disconnect?

“Connected but no internet” means your phone sees the WiFi network and thinks it’s online, but data isn’t flowing — usually a handshake or IP address issue. A full disconnect means your phone drops the WiFi entirely and stops showing the network name. Both are usually fixed by a handshake reset. If a handshake reset doesn’t work, the next step is checking for a newer update or disabling WiFi optimization, which sometimes causes the phone to scan for better networks and briefly drop connection.
