I recently installed Ubuntu 18.04 on my Acer v5, initially alongside windows 10. After installing I had no wifi connection. Doing some research on the net for some answers I read a couple of times that I should disable secure boot. I entered the bios and tried to disable it but I could not select that option. It was jumping right from boot mode to change boot order. Instead I changed the boot mode from uefi to legacy boot, thinking that I could change it back if it was not working. When I restarted my laptop it was showing operating system not found but since then I can not enter the bios anymore to change it back to uefi mode. If I press F2 nothing happens.

According to my engineering boyfriend windows could not be saved anymore so I decided to install ubuntu 18.04 in legacy boot instead but it did not fix the network problem. It can still not find the network adapter. We tried a couple of suggestions we found on the internet but nothing is working. It seems that all the necessary packeges did not came with the version of Ubuntu that I downloaded (from the official website) and installed. I can not plug in a cable as I have no port for that so I can not do any updates or install other stuff. The only thing I can do is download it on another computer and put it on a usb stick. We tried to look for the right driver but could not find one for ubuntu and have not been able to install it. This should be the driver version for windows v6.30.223.170 Broadcom

I hope someone can help me fix this problem.1

That is a real problem without an Ethernet connection.

gcc, build-essential, etc. are not installed by default in bionic. This makes it very difficult to install a dkms package, or build anything from source without any network connection.

It is possible to download and install many packages manually, but it really a hard work for an ordinary user.

I suggest installing the 16.04 release. It is possible to upgrade it to 18.04 later.

Also I consider it a serious bug, that should be reported to the developers.

I asked this question. I hope someone will find a better solution.

I looked into the 18.04 LiveUSB and found that it seems that the required dependencies are included to pool. It is possible to download them manually the same way as dkms and bcmwl-kernel-source.
