Does the Atheros AR5BWB222 card support dual band?

[akb8812]

Hi, I really need a new router and it seems my ISP offers a Linksys E4200 Dual Band router. It's tempting, however I'm not sure if my devices even support 5Ghz. I have a new Acer laptop that has the sucky Atheros AR5BWB222 WIFI card and I'm curious if that one supports dual band.
Also how long is the 5Ghz range, I move my laptop a lot so that's a factor.

without you Laptop model it is hard to find this out but i did happen to stumble across this from: http://www.anandtech.com/show/6066/acer-aspire-v3571g9435-the-value-proposition

802.11n dual-band 300Mb WiFi (Atheros AR9462/AR5BWB222)
Bluetooth 4.0 (Atheros/Foxconn/Hon Hai)
Gigabit Ethernet (Broadcom BCM57785)

this is the best I could come up with because every thing is driver related when you search out the model number of that wireless card. Like I said, it will be easier to get a better answer if you told us the make and model number of the Laptop it came in.

EDIT: the range of 5GHz is less than 2.4 but the channel is much cleaner so while connected you will get a lot less interference. If you find that the range is not enough you can always get a range extender.

Oh sorry. My laptop is Acer Aspire V5-573G. It's brand new, manufactured in July last year.

What are the last digits on the model number? They will be on the bottom of the laptop. These sets of numbers depict the hardware installed.

here is the data sheet on that laptop and it does not mention being a Dual band wireless card so no it is not dual band.

Oh, that's a little bit disappointing. So I guess i'm just getting a regular router.
Although, my computer differs slightly from that one. I have 4gigs in graphics memory. The site i bought it from says: 300Mbps WiFi n 802.11bgn

and I found a number: 5420125akk

It is just a 2.4GHz card capable of transfer speeds of up to 300 Mbps on a 802.11 N network.
