how do i create another interface for my wifi adapter archer T2U nano

hello,
i recently bought a wifi adapter to use with aircrack-ng on my laptop (dell vostro 15 3510) and need help setting it up

https://www.reddit.com/r/archlinux/comm … ons_of_it/
i already followed this tutorial, but it didn't solve my issues, my adapter doesn't show up in `ip link`

Re: how do i create another interface for my wifi adapter archer T2U nano

i took a closer look at the installation of the package and i get missing kernel header errors
```

missing kernel headers are solved with `pacman -S linux-headers`

i'll check if it is working now

Re: how do i create another interface for my wifi adapter archer T2U nano

its shows up now, but the state is always dormant
```
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp2s0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000

i can change the state with `ip link set wlp0s20f0u3 state UP`, but that isn't enough to use it to connect to wifi

Connecting to a WiFi somewhat contradicts

[...] to use with aircrack-ng [...]

but maybe you're just testing the adapter.

Did you follow https://wiki.archlinux.org/title/Networ … n/Wireless after setting the interface "UP"?
