My friend just bought P3 netbook and Dlink 615 router ($20.00 extra) from Purple. Could not connect wirelessly as the error window kept popping up stating that the wireless connection could not find a certificate code. I had never seen like that. I had been working with the wireless routers with all sucess. So I switched to my old Netgear wireless router and all went well. I suspected there is something wrong with the Dlink 615 router. If you have any experience with that. Please share with us. Thanks
