Hey guys I managed to find the answer in here and with the help of google. Basically if your planex CF-GW11H isn't working just edit the file:
/etc/pcmcia/hostap_cs.conf
And add the following lines:
card "PLANEX GW-CF11H Wireless CF Card"
version "PLANEX COMMUNICATIONS INC.", "PLANEX GW-CF11H Wireless CF Card", ""
manfid 0xd601, 0x0005
bind "hostap_cs"
