Laptop Connects To Access Point But Not Phone?

I recently got an access point to extend the wireless range in my house. It is a Netgear WN802T. The long and short of it is, it works fine, i configured it succesfully, it reaches the main router and gets an IP address from it. My laptop connects to it fine without fuss. However, my phone (HTC Desire HD) and tablet (Motorola Xoom) are unable to connect.They can 'see' the access point, but when i connect and put in the passcode, it get's stuck on 'scanning' or 'disconnected'. I've tried turning certain settings on and off, i've tried taking it out of G/N mode and taking it down to B/G mode.

I've tried multiple types of security (WPA-PSK, WPA-PSK 2, TKIP, AES...), the odd thing is, the type of security my main router uses (which the phones connect to without a hitch) does not work. I have tried different channels. My main router's channel is 1, which works perfectly fine. To make sure there is little interference, i set the AP channel to 4. I've also tried auto, no avail.

The laptop doesn't seem to care what i change the settings to, it connects fine and gets the internet perfectly. But my phone and tablet just don't want to play ball. I don't think the router is broken or anything, it works fine, but i think there's some incompatibility issue here that i'm not seeing.
