Maybe its not running full speed because there's not access pointe associated...

Never used it as my access point does not use WPA or even WEP, I keep
it open for my friends that eventually join a lan party here to use.

AFAIK, its a encryption method used by access points to increase
security (someone will point me if I'm wrong). It must be configured
in your access point to work. Another encryption method (pretty easy
to break, in fact, but still add some security) is WEP. It is all set
at the access point.

What about simply:
ln -s /etc/init.d/net.lo /etc/init.d/net.wlan0
/etc/init.d/net.wlan0 start
?
If you have no security and DHCP at the access point, it shall connect to it...

You must know what type of security your access point has. After you
know this, you'll need to edit /etc/conf.d/wireless and configure it.
If (as I said before) you have DHCP, SSID broadcast and no encryption
at your access point, you don't need any of these, just the two
commands above, else you'll have to configure it, take a look at
/etc/conf.d/wireless.example.
