Hello all, I'm new to Mac and was under the impression that my iMac (which I bought a couple of months ago) would be able to find my existing wireless network at home (Netgear router). Initially I had the iMac connected to the router via an ethernet cable. It has been working fine under that setup. Today I moved the iMac upstairs thinking it would find our wireless network, but no dice. Both our iPhone and our iPad are able to find the network. Not to mention the Windows 7 laptop I'm typing this on now. I feel like I'm missing something basic due to my PC based upbringing. Thanks in advance.
