no access to wifi after updating dualboot on HP250 G5 NB
I have install 16.04 LTS some month ago on a HP 250 G5 notebook.
Everything worked fine, but the dualboot was clumsy, as the user had to go into
the bios each time booting the laptop to define what OS to boot.
So i used bootrepair to set up the grub such, that the user gets a grub screen
to select the OS to boot from.
It was quiet some shuffling till I had all obstacles regarding UEFI restriction.
But not the dualboot works as expected.
However, the LAN, bot wired and wifi behaves strangely.
1. WIFI: I can not find any WIFI interface. Although opening the connections
dialog shows the 3 networks that were used before the dualboot upgrade was executed
2. the wired connection is always switch off after boot and has to be switched
from the system settings
I tried to find out what wifi chip the pc is using with
