How to Fix Router DHCP Server Not Working
When your internet suddenly stops working, one common culprit is the router’s DHCP server. This issue prevents devices from obtaining an IP address, leaving you disconnected. If you’ve faced this problem, don’t worry — in this guide, we’ll explain how to fix router DHCP not working with practical, step-by-step methods.
By the end, you’ll understand why this happens, how to troubleshoot effectively, and how to get your devices back online.
What is DHCP and Why It Matters
Before diving into solutions, let’s clarify what DHCP means.
DHCP (Dynamic Host Configuration Protocol) is the service in your router that automatically assigns IP addresses to devices on your network. Without it, your devices cannot communicate with the router or access the internet.
When the DHCP server stops working, you’ll see errors such as:
- “Unable to obtain IP address.”
- “No Internet, secured.”
- Devices connecting but not loading web pages.
Knowing how to fix router DHCP not working ensures a smoother and faster resolution.
Causes of Router DHCP Not Working
Several reasons may trigger DHCP issues. Common causes include:
Router Misconfiguration
Changes in network settings or updates can disable DHCP.
IP Address Conflicts
If multiple devices share the same IP, the DHCP server fails to assign new ones.
Outdated Firmware
Old router firmware often creates compatibility problems.
Hardware Issues
Overheating or faulty router components can cause DHCP failures.
ISP-Related Problems
Sometimes the issue isn’t your router but your service provider. Reliable providers like Dhanote Internet Services minimize such disruptions.
How to Fix Router DHCP Not Working
Now let’s explore proven fixes.
Restart Your Router
The simplest yet most effective step. Power off your router, wait 30 seconds, and restart. This clears temporary glitches.
Verify DHCP Settings
For Windows
- Open Control Panel.
- Go to Network and Sharing Center.
- Select your network and click Properties.
- Check that “Obtain an IP address automatically” is selected.
For Router Interface
- Log in to your router admin panel (usually 192.168.0.1).
- Navigate to LAN or DHCP settings.
- Ensure DHCP Server is enabled.
Update Router Firmware
Visit your router manufacturer’s website and download the latest firmware. Updating often fixes DHCP-related bugs.
Assign Static IP Address
If DHCP isn’t assigning addresses, manually configure one:
- Go to your device’s network adapter settings.
- Choose Use the following IP address.
- Enter an IP (e.g., 192.168.1.50), subnet mask, and gateway (your router’s IP).
Reset Router to Factory Defaults
If misconfigurations persist, reset your router:
- Press and hold the reset button for 10–15 seconds.
- Reconfigure your network settings from scratch.
Check with ISP
If none of the above works, contact your ISP. Providers like Dhanote Internet Services often help diagnose and resolve DHCP or connectivity issues quickly.
Preventing DHCP Problems in the Future
To avoid DHCP failures:
- Keep your router firmware updated.
- Restart your router weekly.
- Avoid connecting too many devices simultaneously.
- Use a reliable internet provider.
By following these preventive measures, you’ll minimize future interruptions.
FAQs
Why is my router not giving out IP addresses?
Your DHCP server may be disabled, misconfigured, or malfunctioning due to outdated firmware or hardware issues.
How do I know if my DHCP is working?
Check your device’s IP settings. If it shows an address starting with 169.254.x.x, DHCP is not working.
Can I fix router DHCP not working without resetting?
Yes, try restarting the router, enabling DHCP in settings, or updating firmware before doing a factory reset.
Should I set static IP addresses instead of DHCP?
Static IPs can help in small networks but aren’t practical for many devices. DHCP is more efficient.
Who should I contact if nothing works?
If troubleshooting fails, contact your ISP. Reliable providers such as Dhanote Internet Services offer expert support.
When your router’s DHCP server stops working, it can feel frustrating. However, with the steps in this guide, you can confidently fix router DHCP not working issues and restore connectivity.
