I have a DGL-4500 that is working normally with my a Workstation, Tivo, X-Box 360, and a Laptop.  I had my PSP connected at one time also.  However I can no longer connect my PSP or an HP 4400 tablet to my router.  I have checked the configuration on the working devices and have set the PSP  & HP Tablet up the same.  The tablet connects fine to other wireless APs. Neither one will connect after I save their configurations.  I get connection to the access point timed out. I have tried WPA-PST (TKIP & AES). The router is set for: WPA Personal, WPA Mode (Auto), Cipher Type (TKIP and AES). I have reentered and save the Key so I know I am using the correct one.  Any Ideas
