Hello. I am new to this forum (and to D-Link routers, having purchased my DIR-655 at the recommendation of a friend). After having a helluva time setting up my router (I have a Mac, so the Setup Wizard feature on the CD wasn't usable), and not being that much of a "techie," I am a little leery of upgrading the firmware on my router. My question is: if I do upgrade the firmware, will I be faced with having to set up the router all over again? Or will all the current settings, which at this point are obviously working or I wouldn't have gotten to this forum, remain the same? Please forgive my ignorance on this and if there is a previous posting answering my question, I'd appreciate being directed to it. Thanks for any help.
