WPA-PSK in Linux

[LinuxBomber]

Does linux support this? Or I need to install some drivers? Because my router was set to this, and it does not connect unless I change that to something LESS secure...

What can I do? Because all other securities are well known for their vulnerabilities...

Well, on my old Sabayon installation it did not support it... I didn't try it on the newer version though..

I had some wifi going on my linux machine, and im almost certain it was running on WPA-PSK. If I remember what wifi detection software I was using ill post a link.

Linux does indeed support this, it's really a matter if the driver Linux is using for your wireless card supports WPA*
A lot of modern distro's come with wpa_supplicant to help you to connect to WPA secured networks.
Here's an example wpa_supplicant config file.

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1

# WPA protected network, supply your own ESSID and WPAPSK here:
network={
  scan_ssid=0
  ssid="wirelessnetwork"
  proto=WPA
  key_mgmt=WPA-PSK
  pairwise=CCMP TKIP
  group=CCMP TKIP WEP104 WEP40
  psk="sup3rs3cr3tz"
}

Then you can do this to obtain a connection to the network specified in the config

bash-3.1$ su
Password:
bash-3.1# wpa_supplicant -Dwext -iwlan0 -c/etc/wpa_supplicant.conf > /dev/null &
[1] 11419      #-D specifies the driver, -i specifies the interface
bash-3.1# dhclient wlan0

Or you can take make it much easy for yourself and use wicd
