Would these devices benefit from a dual band N router?

[BadOmen]

So, here are my devices that currently get wireless from this masterpiece of yore known as WRT54G v2 located in the basement (devices are on 1st floor):

- Older laptop plugged to TV: Intel Wireless LAN (802.11a/b/g)
- Newer laptop: Realtek 802.11 b/g/n Wireless LAN
- TV: Standard IEEE 802.11a/b/g/n - Frequency Band 2412-2484 MHz, 5150-5850 MHz
- Media player: Pivos 802.11n USB Adapter, 300mbps/ 2.4ghz

Would those really benefit from a dual band N router?


What I wanted:
- better internet video streams to the older laptop (no HD, Slingbox mostly)
- stream from a future dlna server to either TV or Media Player.
- NOTE: Range hasn't been a problem. I get wireless everywhere in the house.

I am ready to buy a new router if needed, but:
- I don't think it's time to invest on AC standard yet.
- On the other hand, AC will eventually be approved, so I don't know if it's worthwhile to put $150 on a top dog N router now.

I googled as much as I could. Now I need your thoughts, and they are greatly appreciated.

Devices that are a/b/g or a/b/g/n will benefit from Dual band.

b/g and b/g/n would Not.

And is it worthwhile to deal with A nowadays?
Or 5ghz N adapters are mandatory for something decent on dual band?
Or forget 5ghz adapters and just get a 5ghz Access Point to connect to dual band router?

I thought buying a router was easier...

Get a dual band router. Assign different SSID's to the 2.4Ghz and the 5Ghz wireless networks. Anything that will operate at the 5, do it. The rest, put on the 2.4. fyi, streaming over wireless sucks.

Good, let's see what 802.11a can do then. Now, as AC is on the verge of approval, would it be worthwhile to put more than $100 on a dual band N router right now? Or something cheaper and more simple would be better as a waiting-for-AC router?
