V570 can not see wireless n connection

Question

Hello, I just bought a V570 5 days ago and noticed that the wireless adapter does not find my 802.11n signal but only the 802.11g signal.  While the 2.4 GHz connection is ok, I expected to be able to connect to the faster network.  I've tried to set up the connection manually it still does not show in the available list of connections.  I've tried putting my new laptop within 2 feet of the router - no luck.
This is not a problem with my router - my work laptop (2 year old Lenovo ThinkPad) connects to my  "n" network without a problem, as does my cell phone.  I've checked the adapter settings and have the defaults set - 802.11n Channel Width for Band 2.4  set to 20 MHz and and 802.11n Mode enabled. 
What I find interesting is that when I look at the adapter settings on my work laptop, it shows a setting that my new one does NOT have - 802.11n Channel Width for Band 5.2.  Why do I not see this setting on my new laptop.  Is this a problem?  While I like the laptop, this is bugging me enough to return it if I don't find a solution soon.
Thanks for any help.

Yeah, I know it's a bummer.
I was "burned" by this issue, when I bought my Y470. I just "assumed" that a brand new laptop, would include a wireless card that supported both channels. What I found out, after I received my new system, was that almost ALL laptops coming from Lenovo, only have B/G/N 2.4 Ghz cards. If you want a card with 5Ghz "A" support, you must upgrade the card in your original configuration order. The real kicker is, if you use the Lenovo outlet web pages to buy your system, you can not upgrade most of Idea Pads wireless cards. Those type of upgrades, seem to be only "offered" on Think Pad systems.
However, you can still buy, and install, and upgraded wireless card. I'm just not sure where you can buy it, and still be under warranty. See this thread:

You would think that Lenovo would have a "parts" outlet web site, that I could go to and order an upgraded wireless card. But it's like pulling teeth, to get any kind of "after purchase" upgrade information out of them. I guess they're too busy selling their systems, instead of making sure they get "brand loyalty" such as IBM once did.
Still, I'm very happy with my Y470. And as I've said, I get a 144 Mbs connection using the OEM wireless card. I had to fiddle with my connection settings on the card, and also on my E3200 router, to achieve the 144, but I've gotten good range on the 802.11N, 2.4 Ghz connection. After all, isn't that what it's all about, anyway?
