I'm trying to set up my Raspberry Pi Compute Module 3+ as an access point with an access point with a WiFi dongle.
I'm following this tutorial : https://elinux.org/RPI-Wireless-Hotspot.
I can set up the access point with the dongle EP-N8508GS, but when I try with the TL-WN722N, I have this error:
pi@raspberrypi:~ $ sudo service hostapd start
Job for hostapd.service failed because the control process exited with error code.
See "systemctl status hostapd.service" and "journalctl -xe" for details.
It seems to be a problem with the nl80211 driver but I don't really understand why it works with the first dongle but not with the other one. I want to try with the tp-link dongle because the first one doesn't support AP-mode and crash the kernell when a device try to connect.
