Rock pi4 comes with wifi module but I can’t scan wifi signal
First, make sure your ROCK Pi is model B, check the label on the main board, “ROCK Pi 4B v1.3” should be it.
Then, which image are you running? Check
ifconfig -a command and the output.
Sorry, I can’t wait for the post to pass the review before I can solve this problem in the forum. Now I have packaged the rock pi4B and mailed it back to exchange!
