Hi everyone, I have a mangOH Yellow with WP7702 and I have a problem that blocks me to configure Octave, after I install the windows drivers and connect the device to my computer, when I type “cm radio” I have Power: OFF. When I type “cm radio on” it doesn’t turn on. Why do I have this problem ? ---

Yes I changed impref to “GENERIC” at!impref? !IMPREF: preferred fw version: 02.22.12.00 preferred carrier name: GENERIC preferred config name: GENERIC\_001.051\_000 current fw version: 02.22.12.00 current carrier name: GENERIC current config name: GENERIC\_001.051\_000 and it turned on the radio, thank you! I want to know if it is normal that on Octave the Signal and Battery dont show an icon although the device is synchronized? ---

can you ping the module by ping 192.168.2.2? You might need to shut down firewall in module by: iptables -I INPUT -j ACCEPT ---

Should I reflash my device to put a password and it will works or via Ubuntu could I do a SSH without a password ? ---
