hello there, i’ve connected an external usb wifi adapter to my manjaro laptop.
but it seems that i do not know how to enable the external one and disable the internal one and vice versa.
(n.b.: i’ve connected it to another windows laptop and it was just plug and play there, but not in manjaro)
adapter model: Realtek RTL8188EUS
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 007: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller

get your device names - you will get something this example
$ ip a | grep ' wl' | cut -d' ' -f2 | cut -d':' -f1
wlan0
wlan1
Set one up and the other down - reverse the interfaces for the opposite action
ip link set wlan0 down
ip link set wlan1 up
EDIT: I just remembered some experiments a while ago. When using Network Manager and dhcpcd you may get unexpected behavior.
The device you set down - Network Manager may reactivate the device and assign an IP to it. As this was some testing for a conky to display or not - I have never been troubleshooting the exact behavior although I found it strange.
now after inxi --full --system --admin --verbosity=7 --filter --no-host i get difference in
Device-3: Realtek USB2.0 Hub type: USB driver: rtl8188fu
bus ID: 1-2.2:28 chip ID: 0bda:f179 serial: <filter>
IF: wlp0s20f0u2u2 state: down mac: <filter>
also, performing ip a | grep ' wl' | cut -d' ' -f2 | cut -d':' -f1 now it shows second wireless interface
wlp1s0
wlp0s20f0u2u2
and now it shows two SSIDs for each of the available networks (eg.:ABC(wlp1s0) and ABC(wlp0s20f0u2u2) ).
so i can assume that the driver is installed successfully.
but there is a small problem. though the available networks are show through usb adapter, i can not connect to them.
