I recently followed this tutorial on installing arch-linux.
During that tutorial and connected to a wireless network (WPA2+PSK) through my linksys wireless adapter (WUSB54GR) using the 'wifi-menu' program, and it worked like a charm, I didn't even have to install drivers; I just selected my network and entered the encryption key.
When I installed arch and logged in, I no longer had access to wireless connection; and when I did the command:
The console says:
Please install 'dialog' to use wifi-menu
So I tried doing 'sudo pacman -S dialog', but obviously this did not work, as I did not have an internet connection.
BTW I have no ethernet ports on this pc so I cannot hook it up directly to the router.
