Hello there, I am facing same issue with my wifi card for a long time now.
Actually I can't find a solution. What I can suggest you is to check in "Linux Hardware" page if your chip is still supported by Kernel. (probably not).
The best solution is an external (USB) wifi card. I know not the best actually, but you get it.
What Linux Hardware page do you mean?

Running kernel:

Code:
$ uname -r
5.4.0-105-generic
Thanks, that kernel should work. Try the driver install on the page I likened.

Thanks that's in post #17-

Before I install that driver I want to find out if the chipset of my mobo is still supported in the kernel or not to be certain.
I'm searching now for a hardware page that will help me find out that info.

Code:
dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 2.7 present.

Handle 0x0002, DMI type 2, 15 bytes
Base Board Information
Manufacturer: MSI
Product Name: Z87-GD65 GAMING (MS-7845)

There are no MSI MB in Ubuntu's certified list found here
But that does not mean that it won't work Just that they never sought ubuntu certification.
Mint's list is found here, but it's not an official list Just reports of what works and what does not by users.
Good luck.

That page helps showing that the wifi card is detected but it doesn't confirm that the kernel still supports the chip set for the mobo.
I'll keep looking.
As per this this page your Kernel version is supporting your card.
Probably is a bug of Mint.

Yeah could be a bug:- Thanks.

I looked around a little more online and found out that the RTL8192CE didn't play nice with Arch on certain mobo's either. It's not the first time that Realtek has been an issue for many Linux users so I've learned from this.

Noticed some wireless cards need extra interfacing with Linux. I had various issues but was able to solve them. Various tips below:
1. Disable secure boot. It turned out to be the reason Linux Mint wasn't recognizing my Broadcom wifi drivers.
2. Install Wifi drivers. You can find out how to do this using the ubuntu help page for various drivers https://askubuntu.com/questions/55868/installing-broadcom-wireless-drivers

After completing that step you should be able to see your wifi in the taskbar.
3. Switch on wifi manually using keyboard buttons or the switch. Finally if WiFi shows but does not connect, then you can follow this step.
f
Bash:
ifconfig -a //Should show your card - means you have drivers

ifconfig wlan0 up //Set the card up. If not drivers issue

iwlist wlan0 scan //Scan for wifi. If issues, follow step 3.

You are trying to use/build Realteck drivers from a package. Which is not compatible with your new kernel

Reading that message in the screenshot that you posted, it sounds like that particular module from backport-iwlwifi isn't going to work with your kernel. That's what I get out of that.

What the output of:
Code:
lspci | grep -i network

Were you able to find a solution for the wifi chip issue?

Yeap this is the problem and there is not solution at all. I found that this module is supported by Kernels. 2.4.0 to 2.12.0 I tried almost all of them without results.
A lot of forums are referring to this issue as a bug.
The return of the command that you asked me to try, can see my NIC but "ifconfig" not return it at all.

You could purchase a USB WiFi dongle that works with Linux and it should work out of the box.
TP-Link I think is most popular with Linux.
