I'm trying to buy a new router and I'm seeing N600, N750, and N900.

What are these? Do they make a big difference?

This is just a way of specifying the transmission bandwidth depending on which frequency bands are used, how many bands are available, and how many streams are offered.

  • N600 routers use dual-band 2.4 GHz, with a bandwidth of 2×300Mbps = 600 Mbps
  • N750 routers use 2.4 GHz and 5 GHz, with a bandwidth of 1×300Mbps and 1×450Mbps = 750 Mbps
  • N900 routers use dual-band 5 GHz, with a bandwidth of 2×450Mbps = 900 Mbps

Naturally, you could also imagine other combinations. See also:

I am pretty sure that all dual-band routers are 5Ghz and 2.4Ghz, and it is the antenna array that dictates how much you can push through them. So a dual-band N600 would be 300mbps through each band. – Paul Mar 19 '13 at 10:04
