I have connection problems with my 493G w/r52hn when I am trying to connect using Linux or MacOs client. I am able to see the Access point but it won’t connect to it sending the message “unable to connect”. Everything runs fine with windows.
Here’s a picture of how my security is setup

I was also wondering why I can’t seem to connect in HT mode whit my laptop i’m able to connect at a rate of 300Mbps/150Mbps in N mode but it doesn’t say it connected in the HT mode in the registration Table. Could this be because my wirless card in my laptop isn’t fully HT compatible ?
Thanks for your help.
