My laptop is i386 machine running Ubuntu 18.04.1 lts.
It comes with internal wireless Qualcomm Atheros AR242x / AR542x Wireless wifi (ath5k), and the default currently wireless connection.
I would like to use USB wireless ALFA AWUS036NHA with chipset AR9271 as default wireless adapter.
lsusb shows that Bus 001 Device 003: ID 0cf3:9271 Atheros Communications, Inc. AR9271 802.11n
that means Ubuntu recognizes the presence of this wireless usb
I downloaded firmware-ath9k-htc_1.4.0-97-g75b3e59+dfsg-1_all.deb
But I am not sure what to do with this.
I followed the instructions
sudo apt-get update sudo apt-get install firmware-ath9k-htc
That is all I did,
and of course nothing has changed, my laptop still using the default build-in wireless for internet access.
What are the steps to get my laptop to use the USB wireless AWUS036NHA as default wireless ?
