I'll be buying an iMac soon. I'm a big time novice when it comes to networking but my new location for the computer has no phone line. The router will likely be about 40'-50' from the iMac. I likely wouldn't consider anything but the Airport Extreme if it wasn't so darn expensive. I'm wondering if it's more than I need. I understand that the 802.11n is faster than (g). But I hear that the internet connection is the limiting factor anyway and you won't get the improved speed from (n). The exception would be if you are backing up to an external hard drive wirelessly. I'm not sure what advantage that would give me as opposed to just placing the external drive on my desk? Any other advantages to (n) vs. (g)? Or Disadvantages other than cost? If I decide on (g), what are some good choices for interfacing to a Mac? (my friend is using a Linksys router but I thought I read those were not compatible w/ Mac's?) And if I decide on (n), are there less expensive, yet good choices for interfacing to our Macs? Any input is appreciated. I'm a bit overwhelmed!
