The only difference I can see is the 3700 has gigabit ports. Any other performance differences that anyone can tell me about with these two routers? I already have the 3400 but I am wondering if I chose the wrong router seeing as the 3700 is only ten bucks more. Can anyone tell me what there experiences were or there knowledge of these two products or even opinions. I have a gaming PC hard wired, ps³ wireless, nexus 7 wireless, and LG Media Player wireless in a 1400 square foot house with one wall between ps3 and 2 walls between media player. I doubt range will be an issue with either routers though. I might transfer files between PC's later on but 10/100 should still be pretty good speed or not so much?
