Ok you need to install a driver for your card. In the terminal do this and reboot wifi should be working.
sudo apt install bcmwl-kernel-source
you'll need to be connected via Ethernet.
Good luck.

But using an usb ethernet connector I can't get it to access the ethernet either.

Any further help very welcome.

I searched for "Linux driver for RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller"

and found:

You may be able to install the driver from the live install media. Here is how:
1 pluging live install disk or usb stick.
2. go to filemanager and navigate to /pool/main/d/dkms - install dkms package using gdebi.
3. Go to /pool/main/g/glibc and install in this order libc-dev-bin Then libc6-dev
4. Go to /pool/restricted/b/bcmwl and install bcmwl-kernel-source
5. Issue this command in a terminal modeprobe wl
wifi should be working.
good luck
