On Debian 9.7, 4.9.0-8-amd64

On my laptop I want to enable my wireless card. Laptop keyboard connector (locking clip) is missing so I can't use it's keyboard enable the hardware switch.

Already did

sudo rfkill unblock all 2: phy0: Wireless LAN Soft blocked: no Hard blocked: yes 

firmware-atheros drivers are already installed. Card is a Qualcomm Atheros AR9287.

I already checked my laptop if there are any hardware switches around (external,internal), nope.

I tried using a USB keyboard and emulate Fn + F3 (wifi switch) and was unsuccessful.

Although upon using the Debian installer, I was able to use wifi upon selecting it as my primary network interface (with internet) although it does not adopt to be the default network interface after the installation.

Is there anything else I could do to enable my wireless card?

To clarify I just want to replicate how the Debian installer enabled my laptop's wireless adapter without the laptop's keyboard wifi hardware switch.
