+Run `sudo nano /etc/hostapd/hostapd.conf` and use the following as an example
+```

 # Setup monitor mode of wifi card
-1. Check with `iw dev` which interface to use, in our case `wlan0` on `phy0` is what we want
-2. Double check if `iw phy phy0 info` returns `monitor` in `Supported interface modes`
+1. Check with `iw dev` which interface to use, in our case `wlan1` on `phy1` is what we want
+2. Double check if `iw phy phy1 info` returns `monitor` in `Supported interface modes`
 3. Do the following
 ```
-sudo iw phy phy0 interface add mon0 type monitor
-sudo iw dev wlan0 del
-sudo ifconfig mon0 up
-sudo iw dev mon0 set freq 2437
-iwconfig mon0
+sudo iw phy phy1 interface add mon1 type monitor
+sudo iw dev wlan1 del
+sudo ifconfig mon1 up
+sudo iw dev mon1 set freq 2437
+iwconfig mon1

 # Capture RSS signal of, e.g., sandlab wireless network
-```sudo tcpdump -i mon0 -n -tttt | grep sandlab | awk '{print $8}'```
+```sudo tcpdump -i mon1 -n -tttt | grep sandlab | awk '{print $8}'```
