Wifi-menu invalid interface specification [SOLVED]

Hi dear sirs!

I am a newcomer here and have a little bit of a problem with wireless on my installed arch.

I have a T43 machine and it successfully connected to wifi and downloaded base and packages during the installation.
However, after reboot I ran into a problem renewing my connection.

iw dev - does not give any output. It used to give me wlp4s2 during the installation as my wirless interface

So I go iwconfig and it gives me three interfaces irda0 lo and enp2s0 it says "no wireless extencions" in front of each one

I pacmaned iw, wireless_tools, wpa_supplicant, wpa_actiond, dialog and netctl and it all went perfectly fine

Also, I tried to ip link set [all those interfaces one by one ] up - none worked

lspci, however gives me out my interface card normally as: PRO/wireless 2915ABG for which i need ipw2200 (supposebly it is there because it worked during the installation process)

And if I just run wifi-menu it says: "invalid interface specification" - even thought I only have one wireless interface and it should work fine

Yes, I did the wiki reading and searched quite a bit on the internet, but I don't seem to have any progress.

Any help would be greatly appreciated.

You may need the firmware, chroot into your installation from a live Arch iso, and install the necessary package: ipw2200-fw exit chroot, then reboot into the installation proper and retry, also when using wifi-menu you'll need to specify the interface, for example; wifi-menu wlp3s0

WhooHoo!

Thank you so much opt1mus! Everything works perfectly fine now.

BTW wifi-menu does not need specified interface if you have only one wireless interface on your computer. Well...according to the man page and how it works on my computer now.

Excellent, I've not used wifi-menu in quite a while, as I start profiles manually.

You can now edit your initial post and mark the title as [ SOLVED ].

-- edited, you're right about single interface --
