[arch-general] wireless tools installation without internet access

[Mateusz Lemusisk]

>Firmware (ipw2100 for intel wireless pro) was copied from usb memory to
a /usr/local/ directory.

Firmware for the iwp2100 should be included with the linux kernel since
some 2.6 version
please check lspci -vnn if the module gets loaded

memory device, then installed onto this >old computer?

you could download all the packages needed ( most times iw and
wpa_supplicant and their dependencies) and install them with pacman -U

The wiki has a great page on installing Wifi on Arch
