old_home_router_d-link_dir-809_to_iphone_hotspot.txt

=== Backstory ===
So, while my normal home network was down, I found an old D-Link DIR-809 router lying around. I figured it could be useful to extend my iPhone's hotspot and connect multiple devices at home. After some tinkering, I managed to set it up in repeater mode, and it worked like a charm! Here's how I did it, in case you ever find yourself in a similar situation.

=== Guide: iPhone Hotspot to D-Link DIR-809 WiFi Router (Repeater Mode) ===

1. **Initial Setup**
   - Factory Reset: Start by resetting the router to clear any old settings. This ensures a clean slate for configuration.
   - Use a clean browser (no cached data) to avoid issues during setup.
   - Default Login:
     - Username: admin
     - Password: (leave blank) *Note: This is only for the factory reset state. Change it immediately after setup for security.*

2. **Configure as Repeater**
   - Set Device Mode to "Repeater" (this allows the router to share the 2.4GHz band while connecting to your iPhone's 5GHz hotspot).
   - Repeater SSID: Search for and connect to your iPhone's hotspot (make sure the hotspot is enabled on your iPhone first).

3. **Network Settings**
   - IP Address: Change from 192.168.0.2 to 172.20.10.7 (this ensures it's on the same subnet as your iPhone's hotspot).
   - Subnet Mask: Keep as 255.255.255.0.
   - Gateway: Change from 192.168.0.1 to 172.20.10.1 (this should match your iPhone's hotspot IP).
   - DNS: Change from 192.168.0.1 to 172.20.10.1.

4. **Final Steps**
   - Restart the router 2-3 times if needed (be patient—it can take a moment to stabilize).
   - Verify connection: Ensure devices can connect to the router and access the internet via the iPhone hotspot.

=== Notes ===
- Security: Always change the default router password after setup and use a strong Wi-Fi password for your iPhone hotspot.
- Firmware: Update the router to the latest firmware to ensure security and optimal performance.

=== Final Thoughts ===
This setup saved me when my regular internet was down, and it might just help you too. If you have an old router lying around, give it a try—it’s a great way to repurpose old hardware!
