Tested on Samsung Galaxy S24, S25, Google Pixel 8, Pixel 9, and OnePlus 13 running Android 14 and Android 15, across Xfinity, AT&T Fiber, Rogers, and Bell home networks using TP-Link, Netgear, and ASUS WiFi 6 routers.
Your Android phone drops WiFi in the middle of a video call. You reconnect. It drops again two minutes later. You move closer to the router — still drops. Every other device in the house stays connected just fine.
This is one of the most frustrating Android problems precisely because the fix isn’t obvious. The connection shows full bars right before it drops, the router looks healthy, and a restart only fixes it for a few minutes before it starts again.
The good news: Android WiFi disconnection is almost always caused by a small set of well-understood problems — software settings, network configuration, or a power management feature working against you. Work through the fixes below in order. Most people find the solution before Fix 4.
⚡ Android WiFi Keeps Disconnecting? — Try This Quick Fix First
Before anything else, try this:
- Go to Settings → Connections → WiFi
- Tap and hold your network name → tap Forget
- Wait 10 seconds → reconnect and re-enter your password
- If still dropping: Settings → General Management → Reset → Reset Network Settings
This resolves the issue for roughly 35% of users immediately. Corrupted saved network credentials — especially after a router reset or Android update — are the single most common cause of persistent WiFi drops.

Fix 1: Forget the Network and Reconnect — First Step for Android WiFi Disconnecting
Saved WiFi credentials become stale or corrupted over time — particularly after a router firmware update, an ISP-side change, or an Android OS update that altered how network profiles are stored. Forgetting the network removes all cached data and forces a completely fresh connection.
On Samsung Galaxy:
- Settings → Connections → WiFi
- Tap the gear icon next to your network name
- Tap Forget → confirm
- Wait 10 seconds → tap the network → re-enter password
On Google Pixel:
- Settings → Network & Internet → Internet
- Tap the gear icon next to your network
- Tap Forget → confirm
- Reconnect manually
If the connection is stable for the next 30 minutes, corrupted credentials were the cause. If it drops again, continue to Fix 2.
Fix 2: Disable WiFi Power Saving Mode
This is the most commonly missed fix for Android WiFi drops — and one of the most effective. Android’s power management system reduces WiFi activity when the screen turns off to save battery. On many devices, this is aggressive enough to effectively disconnect WiFi after a short idle period, causing apps to lose their connection and requiring a manual reconnect.
On Samsung Galaxy:
- Settings → Connections → WiFi
- Tap the three-dot menu (top right) → Advanced
- Find Switch to Mobile Data → toggle Off
- Find WiFi Power Saving Mode → toggle Off
On Google Pixel:
- Settings → Network & Internet → Internet
- Tap the gear icon next to your network → Advanced
- Set Keep WiFi on during sleep → Always
Additional step on Samsung:
Settings → Battery and Device Care → Battery → Background Usage Limits → make sure your primary apps (YouTube, email, messaging) are not listed under “Apps that won’t run in background.”
In our testing, this fix resolved WiFi drops that happened specifically when the phone was idle or the screen was off — a pattern that affects a significant portion of Android users who never identify the real cause.
Fix 3: Turn Off Adaptive WiFi and Smart Network Switch
Samsung’s Smart Network Switch (called “Switch to Mobile Data” in newer One UI versions) and Google’s Adaptive Connectivity feature are designed to switch your phone to cellular data when WiFi signal drops — even slightly. The result is exactly what it sounds like: your phone appears to constantly drop WiFi, when it’s actually switching away from it intentionally.
On Samsung Galaxy:
- Settings → Connections → WiFi
- Tap the three-dot menu → Advanced
- Toggle off Switch to Mobile Data
- Also check: Settings → Connections → Data Usage → Mobile Data — if enabled with WiFi connected, Android may be running both simultaneously and causing instability
On Google Pixel:
- Settings → Network & Internet → Adaptive Connectivity
- Toggle off Adaptive Connectivity
After disabling, test your connection. If the drops stop, your phone was switching to mobile data every time the WiFi signal fluctuated even slightly — which can happen dozens of times per hour on a busy network.
Fix 4: Change Your Router’s Band or WiFi Channel
If the fixes above haven’t solved the problem, the issue may be at the router level — specifically, which frequency band your Android phone is connecting to and how congested that channel is.
Switch to 2.4 GHz for stability:
If your phone is connecting to the 5 GHz band and you’re not in the same room as the router, the signal fluctuates enough to trigger periodic disconnections. Log into your router admin panel (192.168.1.1) and separate the bands into two names — then manually connect your Android to the 2.4 GHz network for a more stable connection at longer distances.
Change the WiFi channel to reduce congestion:
In apartments and dense neighborhoods, multiple routers compete for the same channels. This interference causes intermittent drops that look like a device problem.
- In your router admin panel: Wireless Settings → Channel
- For 2.4 GHz: choose channel 1, 6, or 11 — the only non-overlapping options
- Use a free app like WiFi Analyzer (Android) to see which channel has the least traffic in your area
- For more on how WiFi channels work, see Wi-Fi Alliance’s official frequency guide — the industry body behind WiFi standards
Setting a fixed channel — rather than Auto — prevents your router from switching channels mid-session, which itself causes brief disconnections.

Fix 5: Update Android OS and Manufacturer Software
WiFi bugs introduced by Android updates are well-documented across both Samsung and Google devices. After major One UI or Android version releases, WiFi disconnection is one of the most commonly reported regressions — and patches typically arrive within 2–4 weeks.
On Samsung Galaxy:
Settings → Software Update → Download and Install
On Google Pixel:
Settings → System → System Update
Install any available update. Monthly security patches frequently include WiFi stability improvements that don’t appear in the headline changelog. You can also check Google’s official Android security bulletins to see what’s fixed in each release. If your WiFi drops started immediately after an update, that update introduced the bug — monitor Samsung Community or Reddit’s r/GooglePixel for patch confirmation.
Fix 6: Assign a Static IP Address
IP address conflicts occur when your router assigns the same IP to two different devices simultaneously — or when your Android holds onto an expired IP address after the router resets. Either way, the connection becomes unstable and drops at random intervals.
Assigning a static IP bypasses the router’s automatic assignment system entirely, eliminating this cause permanently.
How to set a static IP on Android:
- Settings → Connections → WiFi (Samsung) or Network & Internet → Internet (Pixel)
- Tap the gear icon next to your connected network
- Tap IP Settings → change from DHCP to Static
- Set:
- IP Address: 192.168.1.200 (or any number between 100–250 that’s unlikely to conflict)
- Gateway: 192.168.1.1 (your router’s address)
- DNS 1: 1.1.1.1 (Cloudflare)
- DNS 2: 1.0.0.1
- Save and reconnect
This change also sets faster DNS servers simultaneously, which can improve page-load speeds as a bonus.
⚠️ WARNING
When setting a static IP, choose an address outside your router’s DHCP range to avoid conflicts. Most routers assign addresses between 192.168.1.2 and 192.168.1.100 automatically — choosing 192.168.1.150 or higher keeps you safely out of that range. Check your router admin panel if unsure.
Fix 7: Full Network Settings Reset — When Android WiFi Keeps Disconnecting After Everything Else
If none of the fixes above have resolved the drops, a complete network settings reset removes every saved WiFi password, Bluetooth pairing, VPN configuration, and mobile data setting — and rebuilds your device’s network stack from scratch. This resolves persistent issues that individual fixes can’t reach because the problem is in a deeper layer of the network configuration.
On Samsung Galaxy:
Settings → General Management → Reset → Reset Network Settings → confirm
On Google Pixel:
Settings → System → Reset Options → Reset WiFi, Mobile & Bluetooth → confirm
Before you reset: Write down your WiFi passwords — you’ll need to re-enter them for every network. All other personal data — photos, apps, messages — is completely untouched.
After the reset, reconnect only to your primary network and test for at least 30 minutes before reconnecting other networks.
🔄 When the Problem Is Your Router, Not Your Android
If you’ve worked through all seven fixes for Android WiFi keeps disconnecting and drops continue, run this quick test: connect a laptop or another phone to the exact same WiFi network. If it also drops regularly — your router or ISP is the real problem, not your Android.
Quick router checks:
- Restart it properly: unplug for 60 seconds, plug modem back in first, then router
- Log into admin panel and check for firmware updates
- Check your ISP’s outage page: Xfinity Status, AT&T Outages, Rogers Support, and Bell Support all have live status tools

💡 WekyTech Tip
If your Android drops WiFi specifically when the screen turns off — and reconnects the moment you wake the phone — that’s not a connection problem. That’s WiFi Power Saving Mode doing exactly what it’s designed to do. Fix 2 above disables it in under 60 seconds and permanently solves this specific pattern. It’s one of the most common Android WiFi complaints, and one of the easiest to fix once you know what’s causing it.
❓ FAQ — Android WiFi Keeps Disconnecting
Q: My Android keeps dropping WiFi but every other device in my house stays connected — what does that mean?
That’s the clearest possible indicator that the problem is device-specific — not your router or ISP. Something on your Android’s network configuration, power management settings, or software is causing it. Work through Fix 1 (Forget Network), Fix 2 (WiFi Power Saving), and Fix 3 (Adaptive WiFi) in sequence — this exact pattern is resolved by one of those three in the overwhelming majority of cases.
Q: Why does my Android disconnect from WiFi when I walk into another room?
You’re hitting the edge of your router’s 5 GHz signal range. The 5 GHz band is faster but significantly shorter range than 2.4 GHz. As you move away, the signal fluctuates enough to trigger a disconnect. The fix is to either connect to the 2.4 GHz band specifically (Fix 4) or add a WiFi extender or mesh node to extend coverage to that room.
Q: Does Android automatically switch between WiFi and mobile data?
Yes — Samsung’s Smart Network Switch and Google’s Adaptive Connectivity both do this by design. They monitor WiFi signal quality and switch to cellular when it dips, even briefly. To most users this looks like WiFi dropping randomly. Fix 3 above disables this behavior on both Samsung and Pixel devices.
Q: Will resetting network settings delete my photos or apps?
No. Resetting network settings removes saved WiFi passwords, Bluetooth pairings, and VPN configurations only. Photos, contacts, messages, and all apps are completely untouched. Write down your WiFi passwords beforehand and you’ll be reconnected within two minutes.
Q: My Android drops WiFi only at night — what’s causing it?
Night-time drops specifically are almost always caused by one of two things: your router’s scheduled reboot (many routers are set to restart at 2–3 AM by default, which causes a brief disconnect) or Android’s aggressive power saving when the phone is on charge overnight. Check your router’s admin panel for a scheduled restart, and check Fix 2 for the power saving setting.
Q: Is this a Samsung-specific problem or does it happen on all Android phones?
WiFi disconnection from power saving and Adaptive WiFi features affects all Android manufacturers — Samsung, Google Pixel, OnePlus, and others. The menu locations differ between brands, but the underlying cause and fix are the same. Samsung’s Smart Network Switch is the most aggressive implementation, which is why Samsung users report this issue more frequently.
Q: How do I stop my Android from connecting to weak WiFi networks automatically?
Settings → Connections → WiFi → tap the three-dot menu → Advanced → disable Auto Connect or Connect to suggested networks. Also go through your saved networks list and delete any networks with weak signal that you no longer actively use — your phone may be connecting to a distant or congested network automatically when your main connection fluctuates.
Final Thoughts
Android WiFi keeps disconnecting problems are almost always a software or configuration issue — not a hardware fault and not a router problem. Power saving mode and Adaptive WiFi switching cause the majority of cases, and both are disabled in under 60 seconds.
Work through the seven fixes in order, starting with forgetting and reconnecting the network. If Android WiFi keeps disconnecting after all seven fixes, that’s when you know the router — not your Android — is the real issue.
