I have installed 22.04.3 LTS on an old notebook, and the installation went smooth. The notebook has no built-in Wifi, so I tried using an USB adapter, but I cannot configure the Wifi connection. I tried with two USB adapter: Netgear and TP-Link. After searching for a solution I checked the hardware with the following commands:
Bus 007 Device 004: ID 0846:9021 NetGear, Inc. WNA3100M(v1) Wireless-N 300 [Realtek RTL8192CU]
$ ip link
5: wlx2cb05d5bf4c9: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether 2c:b0:5d:5b:f4:c9 brd ff:ff:ff:ff:ff:ff
Bus 007 Device 005: ID 0bda:8179 Realtek Semiconductor Corp. RTL8188EUS 802.11n Wireless Network Adapter
$ ip link

Do I have to install something or activate the Wifi adapter in any way? Any help would be appreciated. Thanks!
thanks for your answer and for the link, I’ll give it a try. So although the USB adapter is being showed in “ip link” as a network adapter the driver is missing? I ask because I’m accustomed to the behavior of Windows, where a device without a driver is only shown in the device manager as unkown device.
The solution was too easy and somewhat embarrassing for me.
After looking up the systemd journal as you proposed I saw some reference to ‘rfkill’ I tried the command to check the status of the Wifi devices. That’s when I realized that there is a built in Wifi card in this old notebook and that there is a Wifi switch to turn it on/off. And the switch was set to the OFF position…
After turning the switch ON the Wifi connection was not grayed out any more and I could connect to my home Wifi without problems.
So I couldn’t solve the problem with the USB Wifi adapter, but it turns out I don’t need it anyway.
