How to set up WiFi using a WiFi adapter in the form of a USB flash drive?

Question

linux

I have a problem setting up WiFi while installing Gentoo Linux booting from a minimal disk.
The situation is as follows:
1. Notebook: Lenovo ThinPad Edge E120
2. WiFi is built into it, but he went to the forefathers after tasting my tea
3. Instead of a regular and built-in WiFi-adapter was bought in the form of a USB flash drive.
My actions:
0. Look in dmesg, is my WiFi flash drive there? Answer: no!
1. View the output of the command: "rfkill list". As a result, I see that phy0 is disabled both in software and hardware
2. Try to load the driver for my command "modprobe rtl8192cu", then run 'lsmod' and see that it was successfully loaded. Also 'dmesg' entry appeared 'usbcore: registered new interface driver rtl819cu'
3. I look at the output of the 'iw dev' command and see 'wlp2s0'. I follow the output of 'dmesg' again and see that the driver for my built-in WiFi is loaded: 'iwlwifi' and that it is assigned the interface 'wlan0' , and then renamed to 'wlp2s0'
I have a misunderstanding how after loading the module (see p. 3) I can get a new interface for WiFi, which thread is 'wlp2s3' if 'wlp2s0' is busy?

Answer 1

new interface driver rtl8192cu

this is just the kernel module itself, if there are no further messages that it has identified a piece of iron, then it did not see it
look at lsusb, check that it is exactly 8192cu by vid:pid, look in the driver source for the presence of such vid:pid in the driver database
if in there is no base, but the card is exactly on 8192cu - you can force the hardware driver if it is not 8192cu - download the appropriate kmod
