Hey there, My router's been acting funny (old Cisco/netgear router). I'm going to replace my router, but I want to do my homework before I put the cash down. Much to my surprise, there's too much marketing around something as a dull as a wireless router. I want to know what I need to know, among them: -What is 802.11N? what does that even mean? -What is "throughput"? If throughput is 300Mbps, what does that mean? -MIMO? what the heck is that about? -In reality, in a normal household, do I need dual-band? Let's say about 2~3 PCs, 2~3 smartphones. -Gigabit routers? -What's one thing not on here that I (and other future router buyers) should know? On Amazon, the following are ranked top: 1.Securifi Almond- http://amzn.to/XMY63E 2. Medialink- http://amzn.to/Re9x39 3.Airport Extreme- http://amzn.to/RhD4HC 4. ASUS N66U- http://amzn.to/Sk6uV7 I, for the life of me, can't figure out what's different from one another (aside from the first with an obvious touch screen). Any opinions?
