I'm having difficulty setting up my new wireless router with WPA. I've set up the router to be this way but when I try to connect with my laptops they'll connect to the router after an extended period of time but will have limited connectivity. my laptop is an LG E300 with a Ralink N router built in. It allows me to select the WPA setting so I assumed that it would be ok to use with out a problem. Any advice is appriciated.
