Hopefully, there was a firmware update for the Linksys WAP4400N to version 1.2.14. I downloaded a firmware image from Linksys website labelled WAP4400N_Firmware_R1.2.14_01152008.img. It should be corrupted because i never managed to get it recognised by the Linksys device. Hopefully, there's a WAP4400N_Firmware_R188.8.131.52-ETSI_01202008.img firmware available on linksys-uk website which is usable. http://www-uk.linksys.com/servlet/Satellite?blobcol Since the firmware update, my 10.5 802.11n MacIntel work perfectly with the Linksys WAP4400N device.
