I installed Zorin on MacBook 2017, and encountered the problem related to broadcom 802.11 not being recognized. I have tried a direct line from the router to the computer using a special connection (failed). I purchased a Penguin Linux external wifi router (failed). I cannot run update - because, there is not a connection (the date on my new Zorin system has not changed, meaning there is no connection). There is no Secure Boot on this version of Zorin. When I type lshw -c into the terminal, I get the following:
Hardware lister (lshw) -
usage: lshw [-format] [-options ...]
format can be
-html output hardware tree as HTML
-xml output hardware tree as XML
-json output hardware tree as a JSON object
-businfo output bus information
options can be
-class CLASS only show a certain class of hardware
-C CLASS same as '-class CLASS'
-c CLASS same as '-class CLASS'
-disable TEST disable a test (like pci, isapnp, cupid, etc. )
-enable TEST enable a test (like pci, isapnp, cupid, etc. )
-quiet don't display a status
-sanitize sanitize output (remove sensitive information like serial numbers, etc.)
-numeric output numeic IDs (for PCI, USB, etc.)
-notime exclude volatile attributes (timestamps) from output
You should be using bcmwl-kernel-source.
If you cannot currently use hardline or hotspot to get a connection, you may need to use a networked computer to download the packages, then a USB Stick to transfer them:
Installed the ...Oubuntu7~20.04.3-amd64.deb.html after removing Broadcom. Used the Linux Install Tool on Zorin after moving the files using a flash drive, used password, and rebooted. However, in settings the WIFI can now find the network, but cannot log into it, it will not accept the WIFI password, saying the network is encrypted. Signal strenght is excellent, but last used is Never. I also tried an external wifi adapter from Penguin, their latest, it runs into the same problem.
I would have thought the last suggestion here except for your statement quoted above.
Are you using a VPN, LUKS or any other encyrption?
Did you download and install Zorin OS .iso from a primary Zorin OS Mirror?
Those are great ideas. My understanding is that this Zorin does not have secure boot. Nonetheless, I am not dual booting. I do not think MOK is installed on this system, as I have tried to run that to turn off the secure boot and there was some kind of error, which is when I searched and found out there was not a secure boot. In the meantime, I did contact ProtonVPN. Since Zorin is not officially covered by ProtonVPN, they said they are sorry for the inconvenience and will keep working on it to bring Zorin and other OS up to date.
