how to setup wireless LAN

Hello,

I am trying to setup a WLAN connection but running into main problems. After new installtion von ARCH using the wired connection I want to be able to switch between both wired and wireless connection but there seemed to be no interface.

[root@Arch-Host user]# ip link
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: irda0: <NOARP> mtu 2048 qdisc noop state DOWN mode DEFAULT group default qlen 8
    link/irda 00:00:00:00 brd ff:ff:ff:ff
3: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DEFAULT group default qlen 1000
    link/ether 00:0b:5d:9b:20:df brd ff:ff:ff:ff:ff:ff

or

[root@Arch-Host user]# iw dev
[root@Arch-Host rainer]# iwconfig
irda0     no wireless extensions.

lo        no wireless extensions.

enp2s0    no wireless extensions.

during boot I saw an error message like "couldn't load firmware"  together with ipw2200 module. The reason was -2

Does anyone have a description what to do in this case? I have a running Unbuntu Version on the same Laptop. WLan is working there. Is it possible, just to copy some files over to ARCH?

Many Thanks!

Re: how to setup wireless LAN

You need to Install the ipw2200-fw package from the core repo. After the installation your wireless connection should work.

You are using an old notebook?

Re: how to setup wireless LAN

hi, thanks for the quick response!

I went through these pages already. But all I can see, if running "lspci -k" is

06:05.0 Network controller: Intel Corporation PRO/Wireless 2200BG [Calexico2] Network Connection (rev 05)
    Subsystem: Intel Corporation Device 2702
    Kernel modules: ipw2200

but the "Kernel driver in use:..." is missing"

How do I install and load the ipw2200-fw package?

Thanks again! AVFritze

You can use a wired connection or you get this package and its dependencies from another pc and using a USB drive to Transfer it to your notebook.

Re: how to setup wireless LAN

Hi - I made it!
I downloaded the package and copied it to /var/cache/pacman/pkg. Then I tried pacman -S ipw2200-fw and after the reboot everything was fine!

Thanks for your help again!
