I have an Air Station Nfiniti WZR-HP-AG300H--an older model that I'm trying to put in service to replace a naughty competitor. I can connect wirelessly with my laptop from a few feet away, but not with my desktop about 40 feet away. Nor with my Samsung tablet a few feet away, or my iPhone. I'm using the encryption key pasted on the side of the router as the password, but it won't connect wirelessly. It WILL connect if I run Ethernet cables from the router to my desktop. Eventually, I'd like to change the encryption key/password to something I can remember, but for now the printed key doesn't even work (except on that nearby laptop). Can somebody please help me get on wirelessly? Thanks.
