After a little time away from Zorin I have found my way back and installed the latest version. I keep getting random wifi disconnects. I have disabled the power saver and this is the result of lspci:

Up until recently I have been using linux mint and this was happening with that distro as well. I have used a wifi dongle and don't get the disconnects, while I realise using that is an option I would like to try and rectify whatever is causing the issue with the wifi card. Any assistance would be very much appreciated.
Thank you for taking the time to respond. I have done as you suggest, package installed. I will monitor to see what happens.
Ok, so this hasn't worked. I installed the package and rebooted. Initially hopeful but wifi has disconnected 3 times in the last 30 minutes.
Reboot, in bios turn off secure boot.
In the terminal write
sudo apt-get install --reinstall bcmwl-kernel-source
Secure boot was already disabled, the terminal command has been executed. Thank you again for your interest.
No progress unfortunately. Still dropping out with no warning.
Would you mind posting the output of sudo lshw -c network?
Thank you for responding, this is the output you requested:

Try drivers - DPKG error while installation bcmwl-kernel-source on ubuntu 16.04 - Ask Ubuntu
The checked solution on that page.
That's done thanks again. Will monitor and report back.
This appears to have done the trick. Whilst I have no idea what has happened I am very grateful for your help.
