Wifi not working on zorin 17

I'd updated to zorin 17 some months back without hassles, My wifi had been working great until today. I used it for a while during a class and then I put the laptop to sleep and much toy surprise some hours later I put the laptop on and couldn't Access WiFi, the icon wasn't showing in status bar, I checked the settings to see if WiFi is showing, nothing at all. I've updated the system already just to see if that's the issue. I know of the hardware switch on some computers that allows you to disable WiFi, it's enabled so it's not that.
What can I do to solve this?

Can you please post the output of

sudo lshw -C network

Wifi drivers can depend on the Linux kernel and if the kernel changes, they may cause the Wifi Drivers to no longer work. This can be noticed once a system is reinitialized after a change.
If the drivers utilize DKMS (Dynamic Kernel Module Support), then a user can safely change the kernel without having to reinstall the drivers.

If a user dual boots with Windows and Windows "Fast boot" or "Fast startup" is enabled, Windows can retain control over the hardware from, the last run session.
A dual booter can load Windows OS, disable Fast Boot from the control panel > Power options, then ensure Windows OS fully shuts down to release control of the hardware.

Here's the output of
sudo lshw -C network

As per the dual booting thing, I haven't logged into Windows for a while, I've been on zorin since. Fast boot is also disabled, I went through a checklist of things to disable before dual Booting windows and Linux.

The output shows your ethernet, but nothing about wifi. Do you recall offhand what Wifi card you have?

No I don't remember what wifi card I have, what could cause this?

I literally was using the WiFi and all of a sudden it's gone

Could be that the Wifi card has failed. Have you run any tests on it?
Is it getting power?

If this was working for some time before on Z17, I am wondering if software update delivered a new linux kernel.
Have you tried booting an older kernel from grub menu item "Advanced Options for Zorin"?

Also do you just have Zorin 17 or are you dual-booting with Windows?
If the latter, is your wifi visible in Windows?

I'll try the advanced option thing, yes I'm dual booting. I've booted windows, the WiFi isn't showing up as well.

How do I go about running tests on the WiFi card?

Ah. That is not good if also no-show on Windows as well as Zorin.
No need to play with alternative kernels if that is the case.
What PC is it. laptop or desktop. If desktop you could see if the card is physically seated properly. For a laptop you could do the same, but is less easy to do.

In Windows you could go
Start>Device Manager>Network Adapters
doulbe click the card and see if it comes up OK.

Some computers e.g. Lenovo may have Diagnostics software included that can be run from Windows.

I had a wifi card that sometime disappeared. What I did was completely cut the power of the computer in 30-45 min.
Then it reappear after that. Just make sure there's no power at all (including battery).
