[Q] Phone network issue topic

Hello everyone,

Informations
Phone : Nexus 6
ROM : Euphoria OS 1.0 with included kernel

I have a little problem with the phone network...
I have just install the ROM (3days ago) and everything worked fine.
After the first reboot, I had a network problem: no more network (just phone)

Bluetooth is OK,Wifi also ect...

No extra apps installed.

Any idea?
