Hey all. I'm new here on the forums and need help. Now where do I begin?? Well i just purchased the imac g5. This is my 1st time working with a mac. I would like to connect to the internet. Can someone please explain the airport base station to me. I dont know anything about wifi. Are there any open networks i can join once i purchase the base station. Also, i have a cable modem hooked up through ethernet. The problem is, in the network, it says i am connected to the internet. But the problem is, i cant browse any sites. The green light is on next to the built in ethernet. I was wondering can someone help me. Ps- i know that if i have a cable modem that i dont need to use wifi. But i jus would like it explained to me in case i decide to use wifi in the future. Thx alot!
