JeremyB R u there brother???

Can you boot the Mint ISO in UEFI mode to see if the problem is the same.

I found the same issue on MX Linux and that person claims it happened after a BIOS update, they also were booted into BIOS and not UEFI

[Sktweek]

How to check it is Booted in UEFI or BIOS sir??? Whether I have to install one more time???

[JeremyB]

Go into BIOS and set to UEFI only and boot the ISO, see if wifi works. If it works in UEFI, the system might be able to be changed

[Sktweek]

I have been too tired of running the ISO again and again. Is there any other solution to enable my WiFI option in my lap??? and basically my hardware supports WiFI and why???

[JeremyB]

I don't know why it doesn't work in BIOS mode

Ok bro...lemme try and I will post the results.

[cellalpha]

You can try this method
Method One - Fn+F5
Press Fn+F5 (or F5). The Lenovo Wireless Device Settings window will show. ...
On the Lenovo Wireless Device Settings window, set Wireless Network Card On to enable the WiFi, off to disable it.
Or press Win+X on the keyboard to open Windows Mobility Center, and click Turn wireless on.

[Pierre]

Press Fn+F5 (or F5). The Lenovo Wireless Device Settings window will show. ...
that will Disable / Enable the WiFi .. with an pop-up notification.

[Sktweek]

At which place should I press (Fn+F5) In general on home screen it functions as Refreshing sir!

[Pierre]

with Firefox, not being used .. does that option Enable the WiFi
or does it not ? is there any pop-up message ?.

[Sktweek]

Nothing pops up for me....It simple refreshes brother.
