# Networking

The current livecd release 2010.05 doesn't support either the ethernet or the wireless, which can put you in a rather uncomfortable spot, especially if you were hoping to netinstall.

The older kernel in the 2010 build doesn't support either, though newer versions of the kernel do. Use a more recent iso from the [testiso](https://releng.archlinux.org/isos/) to do your install and it should find both cards just fine (for reference, I used 2011.04.10, which is no longer avaliable, see the latest and hope that it works!)

## Wireless

The brcm80211 driver is included in the kernel since 2.6.37\. No further action is necessary on the part of the user. See [Wireless network configuration](/index.php/Wireless_network_configuration "Wireless network configuration") if you have problems.

You can manage your wireless connections with [NetworkManager](/index.php/NetworkManager "NetworkManager") or [Wicd](/index.php/Wicd "Wicd").

# Power Management

## CPU frequency scaling

See [CPU frequency scaling](/index.php/CPU_frequency_scaling "CPU frequency scaling").

# Xorg

See [NVIDIA](/index.php/NVIDIA "NVIDIA") or [nouveau](/index.php/Nouveau "Nouveau").

# Touchpad

You should install *xf86-input-synaptics*, worked out of the box for me with xorg.

If you want to use your mouse without xorg, you can use [GPM](/index.php/GPM "GPM").

# Hotkeys

Volume up/down & mute can be mapped with [xbindkeys](/index.php/Xbindkeys "Xbindkeys").
