I am using a Linksys WRT54G Wireless Router running there current firmware. When I try to connect my PSP to the router it shows the security as WEP instead of WPA-TKIP . I don't want to change my security to WEP just to suit my PSP because I have numerous devices attached to the router wirelessly. (Oh I have connected the PSP to my router before when it used WEP but I changed it a long time ago I wanted to play online a few days ago and it wouldn't let me use it, and when I try entering my WPA key into the next section it says invalid key so I know it's not a Sony typo)
Has anyone else had this problem and any ideas how to fix it?
