Background
I connected MacBook Pro with Raspberrypi3 B+ by Lan and SSH because I have no keyboard and monitor for PI3.
ssh [email protected]
OS : raspbian-stretch-lite
Model : Raspberry Pi3 B+
pi@raspberrypi:~ $ iwconfig
wlan0 IEEE 802.11 ESSID:off/any
Mode:Managed Access Point: Not-Associated Tx-Power=31 dBm
Retry short limit:7 RTS thr:off Fragment thr:off
Power Management:on
lo no wireless extensions.
eth0 no wireless extensions.
Problem
There are many Access Points but No scan results
sudo iwlist wlan0 scan

What should I do?
