Using WI Fi extender.

[Scott]

I have a wi fi extender as recommended by Craig. 

It shows up on my R pi as WLAN 1. Fine

When I tried to disable WLAN 0 in favor of WLAN1 (I need teh improved wi fi RF range) I bricked my R PI. I inadvertently diable WLAN 0 in HW so that screwed things up. 

I do not want WLAN 0 and WLAN 1 getting IP addresses from teh same network that can cause routing problems.

What is the proper method to configure the R PI to use a external WI Fi antenna?

I admit ignorance.

Dont do this !!!!

Permanently Disable the Onboard Wi-Fi (Hardware Level)

If wlan0 is your Raspberry Pi's built-in Wi-Fi module and wlan1 is an external USB Wi-Fi dongle, you can completely turn off the built-in chip at the firmware level. This frees up system resources.

1. Open the boot configuration file:
   sudo nano /boot/firmware/config.txt
   (Note: Use sudo nano /boot/config.txt if you are on an older legacy OS version).
2. Scroll to the bottom of the file and add this line:
   dtoverlay=disable-wifi
3. Save and exit (Press Ctrl+O, Enter, then Ctrl+X).
4. Reboot your Pi:
   sudo reboot [1, 2]

After rebooting with Method 2, your external USB dongle will automatically become the new wlan0 (or remain wlan1), and it will be the only wireless interface available to the system.
