I need help... I'm trying to conncect to the internet and my imac doesn't seem to recognice it? I've read the instructions and I believe I did everything right acoording to the guide...but when I want my imac to recognice it and use the internet wirelessly it doesn't work. Also, I did all the 3 passwords that asked me to create (base password, wireless password and...disk password?) the guest I didn't create a password...but I thought that if I "uncheck it" (or trying to leave it off) other people won't be able to use my wireless...but when I tried my netbook to search for a wireless connection my wireless shows up and I can surf the internet...? and the airport extreme never lid in green...it was always "flashing amber" I believe I already did an update on airport utility but i'm not sure since i'm so confuse trying to figure out how to make my computer to recognize it and how to keep my wireless private so that not other people can use it. Also I'm new to wireless internet connection o_o can someone please help me how to start the airport extreme right?
