I want to have a 5 GHz band for HD TV signals, and a 2.4 GHz band for data. I have looked into some dual band routers, but according to the reviews, I'm not sure that they will do what I want them to do. Also, the dual band routers are more expensive than single band. If I DID get a dual band router, it would have to be true dual band, or simulatneous.
Give the drawbacks of dual band, I was thinking about getting a single band 5GHz router, and employing two routers. I think this would essentially accomplish the same thing as a single dual-band router.
1. Is there such a thing as a single-band 5GHz N router? If so, any suggestions on which one to get?
2. If the answer to the first question is yes, has anyone tried this configuration?
One of the WRT600N’s radios operates in the 2.4 GHz band and supports 802.11b, g, and draft-n devices. The other operates in the 5 GHz band and supports 802.11a and draft-n devices. Wi-Fi 11n devices operate either in the 2.4 GHz band--the case with most--or 5 GHz, or both, as in the case of the N Ultra Rangeplus adapters Linksys introduced to work with this router.
The adapters include a Cardbus model (WPC600N – about $75 online), an ExpressCard model (WEC600N – about $90 online) and, most recently, a USB dongle (WUSB600N – about $90 online). Note that manufacturers’ list prices are quite a bit higher for all of these products, and the brick-and-mortar retail prices we found were also slightly higher. Also note that other draft-n adapters can connect to the WRT600N router, but most only to its 2.4 GHz network.
