need help getting new wifi usb adapter working

wanted more speed.

at moment got two usb wifi adapters installed. used to use slackware and with previous post 14.2 version of slackware I could run dual usb adapters. now only one adapter is useable in slackware and debian.

the Asustek adapter is visible in debian and slackware though realtek adapter driver is loaded. when booting with the Asustek card removed no adapter is detected.

debian renames my asustek card from wlan0 to wlxf46d045dff5a

turns out my RTL8812AU driver is not running. keep getting errors with make and headers on debian buster
