Last Christmas I got an Intel wifi link 5100 AGN. It came with a security key that I have since lost - consisted of many many letters and numbers. I now have an iPod and a Nook that I would like to access my wifi, but am unable to since I do not know the security key. Is there a safe way to change the security key so that both of my laptops, the iPod and the Nook can use the wireless capabilities? I was wondering if I should make the access open, with no security, add those devices, then return to WPA security or if that is even possible if I do not have the security key anymore....what can I do? Any help will be greatly appreciated.
