Is WLAN enabled in BIOS?

**kondob** · March 25th, 2019

Yes.
Config>Network> Wireless LAN and WiMAX Radios [On]

**jeremy31** · March 26th, 2019

You should try resetting the BIOS to defaults and if it doesn't work, shut down the computer remove bottom panel, remove and reinsert wifi card, then boot

**kondob** · March 26th, 2019

It is kind of magic. I begin to dismantle my laptop. But i didn`t finish, cause i want to know where exactly wifi card located
I turn on my laptop and wlan is appear.
Probably maybe some where inside was wrong on hardware.
