Access Point:
Let's start with the AP:
Easy setup, hostapd and a start bash script.
---------------------
/etc/hostapd/hostapd.conf :interface=ath0
driver=madwifi
logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2
debug=4
dump_file=/tmp/hostapd.dump
ctrl_interface=/var/run/hostapd
ctrl_interface_group=0
#hw_mode=g
ssid=miESSID
macaddr_acl=1
accept_mac_file=/etc/hostapd/mac-accept
auth_algs=3
eapol_key_index_workaround=0
eap_server=0
channel=6
wpa=3 ## IMPORTATN! I just discovered that using an atheros card in debian as ap, wpa must be equal to 2 (wpa=2), or conecction will be fucked up
wpa_psk_file=/etc/hostapd/wpa_psk
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
--------------------------
/etc/conf.d/hostapd (for gentoo) :# Space separated List of interfaces which needs to be started before
# hostapd
# Space separated list of configuration files
CONFIGS="/etc/hostapd/hostapd.conf"
# Extra options to pass to hostapd, see hostapd(8)
OPTIONS=""
-------------------
/etc/hostapd/wpa_psk and /etc/hostapd/mac-accept must be created;In wpa-psk file must be you wpa password and in mac-accept all the client's macs that are allowed to connect with the AP. You can set the password directly inside hostapd.conf with "psk=myUbberPassword", but using a file as wpa-psk makes it more flexible and lets you chose one password for each client mac. ( 00:00:00:00:00:00 -> " password for all client macs ") . Examples down here:
------------------
/etc/hostapd/wpa-psk :00:00:00:00:00:00 myUbberPassword
-----------------
/etc/hostapd/mac-accept :
00:FF:FF:FF:FF:FF
00:11:22:33:44:55
00:FF:FF:FF:FF:FF
00:11:22:33:44:55
------------------
This is the script to start the AP:
modprobe ath_pci autocreate=ap
ifconfig ath0 up
iwconfig ath0 rate 54M
iwconfig ath0 essid miESSID
ifconfig ath0 192.168.100.5
/etc/init.d/hostapd start

With the AP running it looks like this (I love wavemon!) :

Clients:
Really easy with wpa_supplicant.
Gentoo:
With ipw2200 card in gentoo just configure /etc/conf.d/net and wpa_supplicant.conf, and run
$ ln -s /etc/init.d/net.lo /etc/init.d/net.eth1
$ rc-update add net.eth1 default
... as root for starting connection on boot (gentoo way).
If you just want to start it from the shell run :
$ wpa_supplicant -d -c /etc/wpa_supplicant/wpa_supplicant.conf -i eth1 -D wext
With madwifi/atheros card just add "wpa_supplicant_eth1="-Dmadwifi" to /etc/conf.d/net . From shell you can connect with :
