Micro: do you need a 'dual-band' Wi-Fi router?
Dec 09, 2012 (Austin American-Statesman - McClatchy-Tribune Information Services via COMTEX) --
If you're shopping for gear to create or improve a wireless network in your home, one question you'll need to answer is whether you want a "dual-band" Wi-Fi router.
When they debuted, dual-band routers were pricey and aimed at early adopters with newer laptops and other bleeding-edge electronics using 802.11n Wi-Fi (faster so-called "Wireless-N" Wi-Fi as opposed to the older "Wireless-B" or "Wireless-G" standards).
Most routers, even ones that could do Wireless-N (also known as 5 GHz), would simply put out a signal compatible with new and old devices or give you the option to go all-N, making for a faster network that shut out older non-N electronics.
Dual-band routers instead create two separate networks, one for older devices (the B and G networks running at 2.4 GHz) and one for faster N devices like newer cellphones, laptops and some video streaming boxes. You might have a Wi-Fi network called "My Home Wi-Fi" and a second network that shows up as "My Home Wi-Fi 5Ghz." This allows the N devices to get faster speeds on the 5 GHz network without sacrificing support for older Wi-Fi gadgets. Dual-band routers have dropped in price as Wireless-N has gone mainstream. Manufacturers like Netgear, Apple and Cisco all make dual-band routers in the $100-$150 range.
