I have a 20' base model iMac with the latest airport card/software and a netgear b/g/n wireless router paired with it. The router took quite some time to set up (December 26th) and is the first/only router ive used so far. Recently though it drops out quite a lot. I will be farting around at lolcat pictures and the signal just goes away. I can see every other network in my neighborhood, so its not an airport card problem right? When it drops out I either scan the signals for a minute or so and it will magically appear again or turn airport on/off and it might come back. So is this a problem with my router, and if so is it a common problem? Im trying to talk my dad into getting the time capsule because I also need a backup hard drive. The computer wired to the router is a pc, will the airport wifi work with the pc? And will I be able to back up the pc onto the time capsule either wirelessly or with a firewire?
