How I Used a D-Link DIR-505 Range Extender with My Mobile to Get Internet via Ethernet

Sometimes the simplest networking problems need creative solutions. I recently faced a situation where I had Wi-Fi internet available on my mobile phone, but I needed a wired (Ethernet) connection for another device. There was no router nearby and no direct LAN source.

That’s when I decided to use my old D-Link DIR-505 travel router / range extender to bridge my mobile internet to Ethernet—and it worked surprisingly well.

Here’s exactly how I did it.


The Problem I Needed to Solve

  • Internet available only on my mobile hotspot
  • Required Ethernet connection for a device (PC, NAS, IP device, or router)
  • No main broadband router available
  • Needed a quick, temporary, reliable solution

The D-Link DIR-505 turned out to be the perfect tool.


What You Need

  • D-Link DIR-505 (Travel Router / Range Extender)
  • Smartphone with mobile data (Android or iPhone)
  • Ethernet cable
  • Device that needs wired internet (PC, laptop, NAS, router, etc.)
  • USB power for DIR-505 (power bank, adapter, laptop USB)

I powered the DIR-505 using a USB power adapter. Once powered on, the device created its default Wi-Fi network.

I connected my mobile phone to the DIR-505 Wi-Fi network.


Step 2: Access the DIR-505 Admin Page Using My Mobile

Using my phone’s browser, I opened:

http://192.168.0.1

This opened the DIR-505 setup page.

I logged in using the default credentials (or previously configured ones).


Step 3: Set DIR-505 to Repeater / Client Mode

Inside the admin panel, I selected Repeater Mode (Wi-Fi Client Mode).

This mode allows the DIR-505 to:

  • Connect to an existing Wi-Fi network
  • Pass that internet to its Ethernet port

Step 4: Connect DIR-505 to My Mobile Hotspot

On my phone, I enabled Mobile Hotspot.

Then in the DIR-505 setup:

  • Scanned for available Wi-Fi networks
  • Selected my mobile hotspot SSID
  • Entered the hotspot password
  • Saved the configuration

After rebooting, the DIR-505 successfully connected to my phone’s hotspot.


Step 5: Use Ethernet Output from DIR-505

Now the important part.

I connected an Ethernet cable from the LAN port of DIR-505 to:

  • A laptop / desktop
  • Or any Ethernet-only device

The device immediately received an IP address and had working internet access.

🎉 Mobile internet → DIR-505 → Ethernet device (success!)


Where This Setup Is Useful

This setup is extremely handy in situations like:

  • Temporary office or site setup
  • Internet testing for wired devices
  • NAS or router configuration without broadband
  • CCTV or IP device testing
  • Travel or emergency connectivity
  • No-router environments

Performance & Limitations

✅ What Worked Well

  • Stable connection for browsing, testing, configuration
  • No additional hardware required
  • Quick setup using just a mobile phone

⚠️ Limitations

  • Speed depends on mobile network quality
  • DIR-505 supports limited throughput (not for heavy traffic)
  • Not ideal for long-term or high-bandwidth usage

New Models of Range Extenders

Final Thoughts

This simple setup saved me time and solved a real-world networking problem without buying new equipment. The D-Link DIR-505, combined with a mobile phone hotspot, works perfectly as a Wi-Fi-to-Ethernet bridge.

If you have an old DIR-505 lying around, don’t underestimate it—it can still be incredibly useful.
