The internet has become an integral part of our daily lives, and staying connected is crucial for various reasons. However, sometimes, you may encounter issues that prevent you from accessing the web, and one such problem is the DNS error on Android. In this article, we will delve into the world of DNS errors, their causes, and most importantly, the solutions to fix them.
What is a DNS Error on Android?
A DNS (Domain Name System) error occurs when your Android device is unable to connect to the internet due to a failure in resolving the domain name of a website to its corresponding IP address. This is similar to looking up a phone number in a phonebook; if the phonebook is incomplete or incorrect, you won’t be able to find the number. In the case of the internet, the DNS server acts as the phonebook, and if it’s not functioning correctly, you’ll encounter a DNS error.
DNS errors can manifest in different ways, such as:
- “DNS server not responding”
- “Cannot resolve hostname”
- “DNS lookup failed”
- “The internet connection is unstable”
These errors can be frustrating, especially when you need to access the internet urgently. But don’t worry, we’ll guide you through the process of fixing DNS errors on your Android device.
Causes of DNS Errors on Android
Before we dive into the solutions, it’s essential to understand the possible causes of DNS errors on Android:
1. Misconfigured DNS Settings
Incorrect DNS settings can cause your device to fail in resolving domain names. This might happen if you’ve recently changed your internet service provider or modified your router’s settings.
2. DNS Server Issues
Sometimes, the DNS server itself may be experiencing technical difficulties, leading to DNS errors. This is often the case when your ISP’s DNS server is down or overloaded.
3. Router Configuration Issues
The router’s configuration can also cause DNS errors. If the router is not configured correctly, it may not forward DNS requests to the correct server.
4. Viruses and Malware
Malicious software can corrupt your device’s DNS settings, leading to errors. Make sure you have an updated antivirus installed on your device.
5. Browser Cache Issues
A corrupted browser cache can cause DNS errors. Clearing the cache and cookies can resolve the issue.
Fixing DNS Errors on Android
Now that we’ve covered the causes, let’s move on to the solutions:
1. Restart Your Router and Android Device
The simplest solution is often the most effective. Restarting your router and Android device can resolve DNS errors by re-establishing the connection and flushing out any temporary issues.
2. Check Your DNS Settings
Go to your Android device’s settings, then navigate to Connections > Wi-Fi > Advanced. Look for the “IP settings” or “DNS settings” option and ensure that it’s set to “DHCP” or “Automatic.” If you’re using a static IP address, check that the DNS server addresses are correct.
3. Change Your DNS Server
Try switching to a public DNS server like Google Public DNS or Cloudflare DNS. You can do this by:
- Going to your Android device’s settings
- Navigating to Connections > Wi-Fi > Advanced
- Selecting “IP settings” or “DNS settings”
- Choosing “Static” or “Manual”
- Entering the public DNS server addresses (e.g., Google Public DNS: 8.8.8.8 and 8.8.4.4)
| DNS Server | Primary DNS | Secondary DNS |
|---|---|---|
| Google Public DNS | 8.8.8.8 | 8.8.4.4 |
| Cloudflare DNS | 1.1.1.1 | 1.0.0.1 |
4. Clear Browser Cache and Cookies
Clearing the browser cache and cookies can resolve DNS errors caused by corrupted data. Go to your browser’s settings, then select “Privacy” or “Security” and choose the option to clear cache and cookies.
5. Perform a Factory Reset
If all else fails, perform a factory reset on your Android device. This will restore your device to its original settings, which may resolve the DNS error.
Additional Troubleshooting Steps
If the above solutions don’t work, try these additional troubleshooting steps:
1. Check for Malware and Viruses
Run a virus scan on your device to ensure it’s free from malicious software.
2. Update Your Router’s Firmware
Outdated router firmware can cause DNS errors. Check with your ISP or router manufacturer for firmware updates.
3. Contact Your ISP
Reach out to your internet service provider’s technical support team to see if there are any issues on their end.
