Wi-Fi Disabled - Keysight Technologies U3810A Getting Started Manual

Wi-Fi Disabled

An improper sequence may disable Wi-Fi in such a way that it looks permanently disabled.
debian@beaglebone:~/temp/LabCode$ connmanctl
Error /net/connman/technology/wifi: No carrier
connmanctl>exit
debian@beaglebone:~$ rfkill list all
0: hci0: Bluetooth
1: phy0: Wireless LAN
1 If the Wi-Fi was blocked by the rfkill command without a reboot, rfkill unblock wifi will
restore it. However, if there was a reboot or power down, after unblocking an additional reboot
will be required.
2 If the wireless is turned off in the /boot/uEnv.txt, then it will not show up as a technology
available in the connmanctl control system.

3 Use cat to examine /boot/uEnv.txt and make sure the disable wireless has a "#" in front of the
line. This is the normal configuration for the disable section of the uEnv.txt file. If necessary, use
the nano editor
