How to Reset Network Settings

Network connectivity issues are among the most frustrating technical problems users encounter across devices—whether it’s a smartphone, laptop, tablet, or smart home system. Slow speeds, dropped connections, failed authentication, or complete loss of internet access can disrupt work, communication, and entertainment. In many cases, these problems stem from corrupted network configurations, conflicting IP addresses, outdated DNS records, or misconfigured Wi-Fi profiles. Rather than spending hours troubleshooting individual symptoms, resetting network settings offers a clean, systematic solution that restores default network parameters and often resolves persistent issues in minutes.

Resetting network settings doesn’t erase personal data like photos, documents, or apps. Instead, it clears saved Wi-Fi passwords, Bluetooth pairings, cellular configurations, VPN profiles, and DNS caches—essentially returning your device’s network stack to factory defaults. This process is especially valuable when standard fixes like restarting the router, toggling airplane mode, or rebooting the device fail to produce results. Understanding how and when to reset network settings empowers users to regain control over their digital connectivity without relying on technical support or third-party tools.

This guide provides a comprehensive, step-by-step walkthrough for resetting network settings across major platforms—including iOS, Android, Windows, macOS, and Linux—along with best practices, diagnostic tools, real-world examples, and frequently asked questions. Whether you’re a home user, remote worker, or IT professional managing multiple devices, this tutorial equips you with the knowledge to resolve network anomalies efficiently and confidently.

Step-by-Step Guide

iOS (iPhone and iPad)

Resetting network settings on iOS is a straightforward process that clears all saved networks, Bluetooth pairings, and cellular configurations. This is particularly useful if your device is failing to connect to Wi-Fi despite entering the correct password, or if you’re experiencing erratic cellular data behavior.

1. Open the Settings app on your iPhone or iPad.
2. Scroll down and tap General.
3. Scroll to the bottom and tap Transfer or Reset [Device].
4. Select Reset.
5. Tap Reset Network Settings.
6. You may be prompted to enter your passcode for confirmation.
7. Tap Reset Network Settings again to confirm.

After the reset, your device will restart automatically. Once it boots up, you’ll need to reconnect to your Wi-Fi networks and re-enter passwords. Bluetooth devices will also need to be re-paired. Cellular settings like APNs (Access Point Names) will revert to default, which is typically fine for most carriers. However, if you use a carrier-specific APN (common with MVNOs like Mint Mobile or Cricket), you may need to manually reconfigure it under Settings > Cellular > Cellular Data Network.

Android (Samsung, Google Pixel, OnePlus, etc.)

Android devices offer a similar network reset function, though the location may vary slightly depending on the manufacturer’s custom UI. The process is consistent across most modern Android versions (Android 10 and later).

1. Open the Settings app.
2. Tap System (on Samsung, this may be under General Management).
3. Select Reset options.
4. Tap Reset Wi-Fi, mobile & Bluetooth.
5. Confirm by tapping Reset Settings.

On Samsung devices, the path may be: Settings > General Management > Reset > Reset Network Settings. On Google Pixel devices, it’s typically under System > Reset options > Reset Wi-Fi, mobile & Bluetooth.

After the reset, all saved Wi-Fi networks, paired Bluetooth devices, and mobile data settings will be erased. You’ll need to reconnect to your networks and re-enter passwords. If you use a custom APN for your mobile carrier, you’ll need to reconfigure it under Settings > Network & Internet > Mobile Network > Access Point Names. It’s recommended to have your carrier’s APN details handy before proceeding.

Windows 10 and Windows 11

Windows provides multiple layers of network troubleshooting, but the most effective way to reset the entire network stack is through the built-in Network Reset feature. This reinstalls network adapters and resets all network components to default settings.

1. Press Windows + I to open Settings.
2. Go to Network & Internet.
3. Scroll down and click Advanced network settings.
4. Select Network reset.
5. Click Reset now.
6. Confirm by clicking Yes when prompted.

The system will disconnect all network connections and begin the reset process. Your computer will restart automatically. After rebooting, you’ll need to reconnect to Wi-Fi or Ethernet networks and re-enter passwords. Network adapters will be reinstalled, and any custom static IP configurations, DNS settings, or proxy configurations will be cleared. This is especially useful if you’re experiencing driver conflicts, IP address exhaustion, or persistent DNS resolution failures.

For advanced users, you can also reset the network stack via Command Prompt by running the following commands as Administrator:

• netsh winsock reset
• netsh int ip reset
• ipconfig /flushdns

After running these commands, restart your computer. This method gives you granular control and is often used by IT professionals to resolve deeper TCP/IP stack corruption.

macOS

Unlike Windows and Android, macOS doesn’t offer a single-click “reset network settings” button. However, you can achieve the same result by manually removing network configuration files and reconfiguring connections.

1. Click the Apple menu and select System Settings (or System Preferences on older versions).
2. Go to Network.
3. In the left sidebar, select each network service (e.g., Wi-Fi, Ethernet, Bluetooth PAN) and click the minus (–) button to remove them.
4. Click Apply to save changes.
5. Now click the plus (+) button to re-add each service.
6. For Wi-Fi, select Wi-Fi, then click Create.
7. Enter your network name and password when prompted.

To fully reset the system’s network cache and configurations, open Terminal and run:

• sudo dscacheutil -flushcache
• sudo killall -HUP mDNSResponder

These commands clear the DNS cache and restart the mDNSResponder service, which handles local network discovery and DNS resolution. You may also delete network preference files manually by navigating to /Library/Preferences/SystemConfiguration/ and removing files like com.apple.network.eapolclient.configuration.plist, com.apple.airport.preferences.plist, and NetworkInterfaces.plist. After deletion, restart your Mac. The system will regenerate these files with default values.

Linux (Ubuntu, Fedora, Debian)

Linux distributions vary in their network management tools, but the core process involves restarting network services and clearing cached configurations. This is especially useful if you’re experiencing DHCP failures, incorrect routing tables, or DNS resolution problems.

For Ubuntu and other systemd-based distributions:

1. Open a terminal.
2. Stop the NetworkManager service: sudo systemctl stop NetworkManager
3. Remove cached network configurations: sudo rm /var/lib/NetworkManager/NetworkManager.state
4. Restart the service: sudo systemctl start NetworkManager

To reset DNS settings, edit the resolv.conf file:

• Open the file: sudo nano /etc/resolv.conf
• Remove any custom DNS entries and replace with a public resolver like Google DNS: nameserver 8.8.8.8 and nameserver 8.8.4.4
• Save and exit (Ctrl+O, Enter, Ctrl+X).

For systems using Netplan (Ubuntu 18.04+), reset network configuration by editing the Netplan YAML file:

• Locate the file: sudo nano /etc/netplan/00-installer-config.yaml
• Replace its contents with a default DHCP configuration:

network:
version: 2
ethernets:
eth0:
dhcp4: true

• Apply the changes: sudo netplan apply

For systems using traditional ifupdown, reset by editing /etc/network/interfaces and ensuring interfaces are configured for DHCP:

auto eth0
iface eth0 inet dhcp

Then restart networking: sudo systemctl restart networking.

Linux users should also clear the DNS cache if using systemd-resolved:

• sudo systemd-resolve --flush-caches

Best Practices

While resetting network settings is a powerful diagnostic tool, it should be used strategically—not as a first resort. Following best practices ensures you maximize effectiveness while minimizing disruption.

Try Simpler Fixes First

Before initiating a full network reset, attempt basic troubleshooting steps. These often resolve the issue without the need to reconfigure everything:

• Restart your router and modem. Unplug them for 30 seconds, then reconnect.
• Toggle airplane mode on and off (mobile devices).
• Forget the Wi-Fi network and reconnect manually.
• Update your device’s operating system and network drivers.
• Check if other devices on the same network are experiencing similar issues.

If these steps fail, then proceed with a network reset. Skipping these can lead to unnecessary reconfiguration effort.

Document Your Current Settings

Before resetting, record critical network configurations you may need to re-enter afterward:

• Wi-Fi network names and passwords
• Static IP addresses, subnet masks, gateways, and DNS servers
• Custom APN settings for mobile data
• VPN configurations and credentials
• Bluetooth device names and pairing codes

Use a note-taking app, spreadsheet, or even a physical notepad. This saves time and prevents connectivity gaps after the reset.

Reset During Off-Peak Hours

If you rely on your network for work, education, or communication, schedule the reset during a time when disruption is least impactful—such as late evening or weekends. Reconnecting to networks and reconfiguring services can take 10–15 minutes, depending on the number of devices and networks involved.

Backup Important Data

Although resetting network settings doesn’t delete personal files, it’s always good practice to back up essential data before performing any system-level changes. Use cloud storage or an external drive to safeguard documents, photos, and other irreplaceable content.

Check for Firmware Updates

After resetting network settings, ensure your router’s firmware is up to date. Outdated router firmware is a common root cause of persistent connectivity issues. Log into your router’s admin panel (typically via 192.168.1.1 or 192.168.0.1) and check for available updates under the Administration or Advanced Settings section.

Use Wired Connections for Verification

If possible, connect your device directly to the router via Ethernet after resetting. This helps determine whether the issue lies with your device’s wireless adapter or the broader network infrastructure. If the wired connection works, the problem is likely with Wi-Fi configuration or interference.

Monitor for Recurring Issues

If network problems return shortly after a reset, there may be a deeper underlying issue:

• Interference from other wireless devices (microwaves, cordless phones, baby monitors)
• Router hardware failure or overheating
• ISP outages or throttling
• Malware or network hijacking

In such cases, consider using network diagnostic tools (covered in the next section) to identify patterns or anomalies.

Tools and Resources

Effective network troubleshooting requires more than just resetting settings—it demands diagnostic tools to identify root causes and verify fixes. Below are essential tools and resources for each platform.

Windows Diagnostic Tools

• Network Troubleshooter: Built into Windows Settings > Network & Internet > Status > Network troubleshooter. It automatically detects common issues like incorrect IP configuration or driver problems.
• ping: Open Command Prompt and type ping google.com to test connectivity. If replies are received, your connection is functional.
• tracert: Type tracert google.com to trace the route packets take to reach a destination. This helps identify where a connection is failing.
• nslookup: Use nslookup example.com to test DNS resolution. If it fails, your DNS server may be misconfigured.
• Wireshark: A free, open-source packet analyzer for advanced users. It captures and analyzes network traffic to detect anomalies, protocol errors, or unauthorized access.

macOS Diagnostic Tools

• Network Utility: Found in Applications > Utilities > Network Utility. Provides ping, traceroute, DNS lookup, and port scan functions.
• Terminal Commands: Use ping, traceroute, and dig (a more powerful DNS lookup tool than nslookup) to diagnose connectivity.
• Console App: Check system logs for network-related errors under “System Reports” or search for “airport” or “Wi-Fi” to find connection issues.

iOS and Android Diagnostic Tools

• Wi-Fi Analyzer (Android): A free app that shows signal strength, channel congestion, and nearby networks. Helps identify interference from neighboring routers.
• Network Analyzer (iOS): Available on the App Store, this app provides detailed information about your Wi-Fi connection, including IP, DNS, and signal quality.
• Speedtest by Ookla: Available on both platforms, this tool measures download/upload speeds and latency. Useful for determining if your ISP is delivering promised bandwidth.

Router Diagnostic Tools

Most modern routers include built-in diagnostic panels accessible via a web browser:

• Check connected devices to identify unauthorized users.
• Review connection logs for repeated disconnections or authentication failures.
• Use bandwidth monitoring to detect abnormal usage patterns.
• Test signal strength across different channels; switch to 5 GHz if interference is high on 2.4 GHz.

Online Resources

• DownDetector (downdetector.com): Check if your ISP or a service like Netflix or Discord is experiencing widespread outages.
• Cloudflare DNS (1.1.1.1): A fast, privacy-focused public DNS service. Consider switching to it if your default DNS is slow or unreliable.
• GitHub Gists: Search for community-shared network configuration templates for Linux, macOS, or enterprise environments.

Advanced: Network Configuration Scripts

For IT administrators managing multiple devices, automation can streamline resets and reconfigurations:

• Windows: Use PowerShell scripts to automate network adapter resets and DNS updates.
• macOS: Create Automator workflows to reset network interfaces and reload configurations.
• Linux: Write Bash scripts to restart services, flush caches, and apply Netplan configurations in bulk.

Example Linux script:

!/bin/bash
sudo systemctl stop NetworkManager
sudo rm /var/lib/NetworkManager/NetworkManager.state
sudo systemctl start NetworkManager
sudo systemd-resolve --flush-caches
echo "Network reset complete."

Save as reset-network.sh, make executable with chmod +x reset-network.sh, and run with sudo ./reset-network.sh.

Real Examples

Example 1: Remote Worker with Unstable Wi-Fi

A freelance graphic designer in Chicago noticed her MacBook would disconnect from Wi-Fi every 15–20 minutes during video calls, causing dropped audio and frozen screens. She restarted her router, toggled Wi-Fi, and even re-entered her password—but the issue persisted.

She followed the macOS reset procedure: removed all network services, rebooted, and re-added Wi-Fi. She also flushed the DNS cache using sudo killall -HUP mDNSResponder. Afterward, the connection stabilized. Further investigation revealed her router was broadcasting on a congested channel (Channel 11). She switched to Channel 6, which reduced interference from neighboring networks. Her video calls became seamless.

Example 2: Android Phone Unable to Connect to Home Network

A college student’s Samsung Galaxy S23 suddenly refused to connect to his home Wi-Fi, showing “Saved, Secured” but never obtaining an IP address. He tried forgetting the network and rebooting, but the problem remained.

He performed a full network reset via Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth. After rebooting, he reconnected to his network and entered the password again. The connection established immediately. He later learned his router had recently updated its firmware and changed its DHCP range, causing IP conflicts with his phone’s cached lease. The reset cleared the stale configuration.

Example 3: Windows PC with DNS Resolution Failures

An IT manager at a small business reported that several Windows 11 PCs couldn’t load internal company websites, though they could access external sites like Google. The error message was “DNS_PROBE_FINISHED_NXDOMAIN.”

He ran ipconfig /flushdns and ipconfig /release followed by ipconfig /renew, but the issue remained. He then performed a full network reset via Settings > Network & Internet > Advanced network settings > Network reset. After rebooting, he manually configured DNS to use Cloudflare’s 1.1.1.1 and Google’s 8.8.8.8. Internal sites loaded correctly. The root cause was a corrupted DNS cache and misconfigured DNS forwarders on the corporate DHCP server—issues resolved by resetting the client-side stack.

Example 4: Linux Server with Intermittent Connectivity

A sysadmin managing a Ubuntu server hosting a web application noticed intermittent 502 errors. Ping tests showed packet loss, and DNS lookups occasionally timed out.

He checked the network configuration and found that the server was using a dynamic IP assigned by DHCP, but the lease was being renewed inconsistently. He switched to a static IP and flushed the DNS cache using sudo systemd-resolve --flush-caches. He also disabled NetworkManager and switched to using systemd-networkd for more reliable control. Connectivity stabilized, and server uptime improved significantly.

Example 5: Traveler with Public Wi-Fi Authentication Loop

A business traveler in Tokyo couldn’t complete the captive portal login on a hotel’s Wi-Fi. The login page would load, but after submitting credentials, it would redirect back to the login screen in a loop.

He reset network settings on his iPhone, then connected to the network again. This time, the captive portal appeared correctly, and he was able to authenticate. The issue was caused by a corrupted cached authentication token from a previous session on a different network. Resetting cleared the conflicting data.

FAQs

Will resetting network settings delete my files or apps?

No. Resetting network settings only clears configurations related to Wi-Fi, Bluetooth, cellular data, VPNs, and DNS. Your personal files, photos, documents, apps, and app data remain completely intact.

Do I need to reset network settings on my router too?

Not usually. Router resets are a separate process and should only be done if you suspect the router itself is malfunctioning or misconfigured. Resetting your device’s network settings is sufficient in most cases. Only reset the router if you’ve tried everything else and other devices are also experiencing issues.

Why do I have to re-enter Wi-Fi passwords after a reset?

Network settings resets erase all saved network profiles for security reasons. This prevents unauthorized access to networks if your device is lost or stolen. You’ll need to manually reconnect and re-enter passwords for each network.

How often should I reset network settings?

Never as a routine maintenance task. Only reset when you’re experiencing persistent connectivity issues that other troubleshooting steps haven’t resolved. Frequent resets can lead to unnecessary reconfiguration and may mask underlying hardware or ISP problems.

My device still won’t connect after a reset. What now?

If resetting network settings doesn’t resolve the issue:

• Test with a different network (e.g., mobile hotspot) to isolate the problem.
• Check for operating system updates or driver updates.
• Run hardware diagnostics (e.g., Apple Diagnostics or Windows Memory Diagnostic).
• Consider replacing the network adapter if it’s faulty (common in older laptops).

Can resetting network settings fix slow internet?

It can, if the slowness is caused by misconfigured DNS, IP conflicts, or corrupted routing tables. However, if your ISP is throttling your connection or your router is outdated, a reset won’t improve speed. Use a speed test tool before and after to measure actual performance changes.

Is it safe to reset network settings on a work device?

Yes, as long as you document your corporate network settings (like VPNs, proxy servers, or internal DNS addresses) before resetting. If you’re unsure, consult your organization’s IT policy or documentation. Never reset a managed device without authorization if it’s part of a corporate network.

Does resetting network settings affect Bluetooth devices?

Yes. All previously paired Bluetooth devices (headphones, keyboards, speakers, smart home gadgets) will be unpaired. You’ll need to re-pair them manually after the reset.

What’s the difference between resetting network settings and factory resetting?

Factory resetting erases all data, apps, and settings, returning the device to its original out-of-the-box state. Resetting network settings only clears network-related configurations. It’s a targeted fix, not a full wipe.

Can I undo a network settings reset?

No. Once reset, the previous configurations are permanently deleted. That’s why documenting your settings beforehand is critical.
