Can anyone tell me what Netbooks, or any mini laptops that have 2.4 and 5Ghz wireless N capabilities? I have searched and can't find where it breaks it down. I even tried just searching for specs for the wireless card that was in some of the laptops, but to no avail. I cannot find this anywhere. Please help me.

It doesn't need to be a netbook, just small enough for a field network engineer to take with him.

Are USB adapters out of the question? As long as the wireless card in the laptop/netbook is wireless N, then you can connect to 2.4 and 5ghz.

HERE is a link about the different wireless bands (2.4, 3.6, 5)

HERE is a very cheap, high quality, very small laptop that will do what you need it to, with a 10/100/1000 network port since he is doing network-work. Has a built in b/g/n card.

HERE is a slightly larger screen but approx same specs.

No, not entirely out of the question. I'm actually doing research for my boss and he prefers it be built in. I've been calling all the major Brands and asking them but their reps dont know crap. When I asked if a certain netbook was dual band they came back with "Well, it's wireless b/g/n" EVERYTIME, and every company; they had no clue. Even when I explained to them I wanted to know if it supports 2.4GHz and 5GHz they would say well n is both... gee thanks! But to get off my rant, we could always upgrade the internal wifi card, right?

Yes you can upgrade the internal WIFI device, BUT a wireless N card is able to do both bands. So the two links for laptops I sent you can connect to both bands.

Realtek RTL8188CE

Not necessarily... you would think so but the Realtek RTL8188CE 11n Wireless card only does 2.4GHz band. That is in the Dell Inspiron Mini 10... If you you scroll down to the bullets towards the bottom of that link it says it's a "Complete 802.11n solution for 2.4GHz band"... It is only dual band in the sense that its 20MHz and 40MHz, but not 2.4GHz and 5GHz :/

I already posted this but I don't see it so here goes again.... Also, in the Dell Latitude 2120 Netbook you have these option for wifi cards... Broadcom BGN (802.11 b/g/n 1x1) and Broadcom AGN (802.11 a/g/n 2x2) even though both are 802.11n only the AGN is is dual band. Not to mention its twice as much as the mini and won't ship until the 15th.

If you read the wiki leak I posted, go down to the section under protocols, it will show you that the 802.11 protocol for N released in Oct 2009, operates on bandwidthes of 20mhz and 40mhz, for frequencys of 2.5ghz and 5ghz.

It adds MIMO(multiple in/multiple out) technology to make use of 2.4 or 5.

To me, it seems that a wireless N reciever will be able to connect to a 5ghz signal.

To be honest though, from what im reading it doesnt specifically state the difference between wireless N transmitters using MIMO for 2.4 and 5, and wireless N recievers being able to connect to both.

I have a USB adapter that can connect to 2.4 or 5, but i no longer have the box, i will look into the specs on my piece when i get home and tell you what i find. It is a wireless N adapter, it did say dual band on the box, but if it was special compared to other wireless n adapters, IDK.
