Currently I have a cable modem which is connected to a Linksys 54 series wireless router. Its single band, that much I am sure of. I will check when I get home as it might to N but I am not sure. Regardless, would it be noticeable if I upgraded my home to a dual band router like Apple's Extreme line; not bad pricing if purchased as refurb; or will the ATV2 do just fine otherwise? I am looking to swap to Netflix for some TV shows. Most movies I watch are blu-ray and I am not worried about changing that. Just want to make sure that I don't make for a bad ATV2 experience because of my existing hardware.
