Unrelated: Don't factory reset your router. The software to set it up requires you to downgrade to 10.7 or something. It'd be nice if linksys would update their software, or at least remove the version cap.

I didn't have to use any special software to set up my Linksys E4200, either when it was new or this year.

You can always use the web interface to set it up, it's just 'easier' for non-technical consumers to use the software.
