Dual or single band

post #1 of 8
Thread Starter 
I am unsure whether I should fork over the cash to get the dual band. I am generally running 4 computers on the same network, 3 wireless, 1 wired. Should I get dual band? And how exactly does it work?

dual band is always good. if your devices can support it. dual band works by sending out a 2.4ghz and 5ghz frequency which you can set your devices to use. it keeps the band/channel less crowded and allows better connection.

Main benefit is being able to have an AP in the 5 GHz range.
2.4 GHz is pretty populated due to B/G/Phones/Microwaves/Bluetooth/Etc.

Of course, your wireless card in each PC will have to support this as well.

But I'm talking about a router like D-Link DIR-815, which purportedly supports "simultaneous" dual band. I assume that means that I can have my connection on 5 ghz while the other computers are on the 2.4 ghz line? amirite?

Definitely go with simultaneous dual band. Everything in my house is N/gigabit, except for that stupid ps3.

So does everything in my house need to be N even though the only thing in the house that is N is my computer? My siblings use G, while I use N. The router should still work on their computers, right? And with this dual band thing, I will be able to separate the bands so that I get to hog the 5 band while they have fun with the 2.4?

Yes, you can use the 2.4GHz band for 802.11g and the 5Ghz band for 802.11n.


Another cheaper option would be to just get a non-simutaneous dual-band router and use it for the 5GHz N You can just use your existing router for 2.4Ghz G.


On the other hand, do you need 5Ghz N? It is noticably more expensive than a 2.4GHz-only N router.

Correct me if I'm wrong but doesn't 5ghz also have a larger bandwidth then 2.4? So if you are using 5ghz you can do more without bogging downing your network. Stream movies/music from a HTPC, game on line, surf and what have you. I know before I got my dual band router if I wanted to stream videos to my xbox from my desktop's tv tuner I would get poor performance because my bandwidth was limited. No I don't have any problems.
