Is your Wi-Fi painfully slow on your laptop or phone? You’re not alone. Whether you’re trying to stream, game, browse, or join a video call, a sluggish connection can ruin everything. But here’s the good news — in most cases, you can fix slow Wi-Fi on your own without calling your internet provider or buying new gear.
In this 2025 step-by-step guide, we’ll show you how to fix slow Wi-Fi on your devices, what causes it, and how to speed it up — fast.
Why Is My Wi-Fi So Slow?
Before jumping into solutions, let’s look at the common reasons your Wi-Fi might be crawling:
- Distance from router – The farther you are, the weaker the signal.
- Outdated hardware – Old routers can’t handle modern speeds.
- Bandwidth hogs – Too many users or devices slow everything down.
- Interference – From walls, microwaves, Bluetooth devices, or neighboring networks.
- Poor DNS server – Slower DNS = slower browsing.
- Background apps and updates – Hidden apps may be eating bandwidth.
- Malware or security issues – Viruses and intruders steal speed.
Quick Pre-Check Before You Begin
- Restart your router and device.
- Do a SpeedTest (speedtest.net) to check actual speeds.
- Try switching to mobile data — is it faster?
- Test the Wi-Fi on another device — if it’s slow there too, it’s not your phone or laptop.
12 Ways to Fix Slow Wi-Fi on Laptop or Phone
Let’s now dive into proven solutions that work:
1. Move Closer to the Router
Wi-Fi signals lose strength through walls and floors.
Try:
- Moving your device closer.
- Placing your router in a central, open location.

2. Change Wi-Fi Frequency (2.4GHz vs 5GHz)
Most modern routers have dual-band Wi-Fi:
- 2.4GHz: Wider coverage, slower speed.
- 5GHz: Shorter range, faster speed.
Switch to 5GHz if you’re near the router.
3. Restart or Update Your Router
Old firmware = poor performance.
- Log into your router settings (usually at 192.168.1.1).
- Check for firmware updates.
- Reboot it every week for best performance.

4. Forget Network and Reconnect
This resets your connection settings:
- Go to Wi-Fi settings → Select your network → Tap Forget
- Reconnect and re-enter password
This often fixes iOS or Android glitches.
5. Switch DNS Servers
Default DNS from your ISP might be slow. Try:
- Google DNS: 8.8.8.8 / 8.8.4.4
- Cloudflare DNS: 1.1.1.1
Use the free 1.1.1.1 app (for mobile) or set DNS manually in Wi-Fi settings.
6. Use a Wi-Fi Analyzer App
Use apps like:
- NetSpot or WiFi Analyzer (Android)
- AirPort Utility (iOS)
These apps show weak spots, channel overlaps, and best locations for routers.
7. Limit Bandwidth Hogs
Streaming, downloads, and Zoom calls eat bandwidth.
- Pause background updates
- Restrict smart TVs or cameras temporarily
- Set device priority in your router’s QoS settings
8. Use Ethernet (for Laptops)
Want guaranteed speed? Use a wired connection.
- Laptops with Ethernet ports: plug in directly.
- No port? Use a USB-to-Ethernet adapter.
9. Install a Wi-Fi Range Extender or Mesh System
If you live in a large house or apartment:
- Range extenders boost coverage in dead zones
- Mesh systems like Google Nest Wi-Fi or TP-Link Deco offer seamless coverage
10. Reset Network Settings (Mobile Only)
⚠️ Use with caution — this will reset all Wi-Fi and Bluetooth connections.
- iPhone: Settings → General → Transfer or Reset → Reset Network Settings
- Android: Settings → System → Reset → Reset Wi-Fi, Mobile & Bluetooth
11. Scan for Malware
Spyware can slow your internet by sending data without your knowledge.
- Use antivirus like Malwarebytes, Bitdefender, or Avast
- Run a full scan and remove suspicious apps
12. Upgrade Your Router (Last Resort)
If your router is over 5 years old, it might not support high-speed Wi-Fi.
Look for:
- Wi-Fi 6 support
- Dual-band or tri-band capability
- Gigabit LAN ports
Best routers in 2025:
- ASUS RT-AX88U
- TP-Link Archer AX73
- Google Nest Wi-Fi Pro
Frequently Asked Questions (FAQ)
Q: Why is my Wi-Fi only slow on my phone?
A: Could be due to app updates, background sync, or old cache. Try restarting or resetting network settings.
Q: Why is Wi-Fi slower upstairs?
A: The signal weakens with walls and floors. Use mesh systems or position the router higher.
Q: Does VPN slow down Wi-Fi?
A: Yes. VPNs encrypt your data and route it through other servers. Turn it off temporarily to test speed.
