USB Wi-Fi adapter for Raspberry Pi 4

I have built a trail camera using a Raspberry Pi 4, a Hi Quality camera with a 8-50 mm zoom lens, a 20 amp hour power block running MotionEyes. It connects using the built in W-Fi adapter. I purchased a SimpleCom NW392 USB Wireless N WiFi Adapter and a TP-Link 16 db Yagi external antenna to replace the internal Wi-Fi adapter. My question is, how do I configure the external USB Wi-Fi adapter? MotionEyes supplies instructions for configuring the internal Wi-Fi adapter, but not an external adapter.

The SimpleCom web site shows drivers for Linux v4.3.0.4 and Linux v4.2.2.

Thanks for your help,
Charles Hart


Hi Charles,

The first test I would do is use the command


in the Raspberry Pi terminal to see if the USB adapter is appearing as a connected device.

It’s not clear what Linux driver version will be the most suitable for the Raspberry Pi as it’s tied to the kernel version, I might need to do a bit more digging there and get back to you unless someone else is more familiar with Linux driver versions.


This is the result that I get when connected to MotionEyes using Putty…

Not motioneyes OS, but on my RPi 4, I plugged in an USB wifi, did not have to configure anything. Were you able to connect to a network with the adapter connected? May be try disabling internal wifi and connect with the adapter?


simple lsusb gives me this:

If the Wifi adapter is connected and recognized, it should be shown as such.
