jorge, Have you tried that firmware?

Do you have TL-WN822N v1 or v2？ refer to http://www.tp-link.com/common/Promo/en/win8compatibility/

mine is v2, FW is 120712. maybe you try as Vivian suggested, to remove the profile on your computer

No, you do not need to enable the WDS on the Netgear. The AP and the router are close to each other with a cable connected?

that's weird, for the SSID just disappeared from my computers when i set it to client mode.

You need to open the media player first, and search the file on media player. what is windows version? windows XP or 7? You can go to this website to check if the PS3 supports the format...
