I want to connect my pi3 wirelessly, for that i need a hotspot wifi. But hotspot should be on laptop which is Ubuntu 16.04 LTS on it. When i try to scan all wifi on Pi it can see only Windows-Android etc. I tried all channels to make Pi can see the Ubuntu's wifi, but Pi still cannot see Wi-Fi Hotspot on Ubuntu(btw other devices can see Ubuntu's Wi-Fi). I already can use 12-13 when i check wlan0 channels. (I already set wifi country IE on raspi-config)
Could you help me please to figure this problem ?
Edit: with same laptop on windows 10 hotspot option can visible on Pi3 as well.
