how do I configure for just 'n' only devices?

I have a new laptop running windows 7 64 bit with 'N' capabilities. Also in my environment are 2 other laptops with 'g' capabilities and we're all using a 'g' router from belkin. I will want to upgrade to a 'n' router at some point that will allow me to take advantage of the faster speeds that 'n' provides without having the 'g' machines slow down the network.
Can a router be designated for just one type of service, such as 'n' only? How is this done? Should I be looking at dual band or just adding another 'n' router to the existing network...and if so how are they connected?
ALso, what is the diff btwn an access point and a router? I don't quite understand when someone says to merely add an access point to your router for 'n' only use. Thanks...

 

Yes, Most routers can be set for "N only" , found under the wireless settings.

A AP is the wireless side of a wireless router. In most cases a AP only may be almost the same price as a wireless router. The reason most just use a router and config it as a AP. You can get SMB class AP that have a lot better performance than residential routers. I prefer AP connected to wired only routers.

A dual band dual radio will allow your to seperate 11n from 11g/b, this way one does not impact the other performance (maybe depending on firmware).

 

I've actually posted about this before:
If you want the highest speed on your wifi and your house isn't A: Huge B: made entirely out of lead or concrete, I would wait for a 3 spatial stream (think mid-late spring) 802.11n AP with dual band and operate your 802.11n at the least tolerant, most stringent settings at 5Ghz. Keep your g (in fact disable b entirely, it will slow down g, too) on 2.4Ghz.

If you run both on 2.4Ghz you either A: limit 802.11n performance B: Gain a bit more on 802.11n, but essentially cripple existing 802.11g.

 

Thanks for responses, much appreciated. I am however leaning towards waiting for the next gen of 'N' routers as suggested by hceuterpe.
I would have to assume, perhaps incorrectly, that there will be more windows 7 compatible stickered products that will operate more efficiently with my laptop too. Do you think there will be more 5ghz 'N' routers coming on to the market and how do I know my HP DV6T can operate at that frequency?
thanks again...

 

u want dual band (i have linksys wrt610n) set to N only on 5 ghz with wide channel and wpa2 security u will get top speeds of 270-300mbps then set the 2.4 to G and your all set
