Having wifi issues with the tx2. I cannot start a wireless access point, or connect to an existing wifi hotspot.

I’ve set /etc/modprobe.d/bcmdhd.conf
options bcmdhd op_mode=2

When I disable disable hostapd, it still fails, and try to find a network via network manager or manually via /etc/network/inferfaces, it fails to find a network and powers down. I’ve copied the working configuration settings (hostapd,dnsmasq,/etc/network/interfaces) from another tx2.

Hi,

Please try upgrading to rel-32.x and directly use the GUI to create wifi ap to test the functionality first. Thanks
