Is this card is dual band: 2.4 GHZ and 5.0 GHZ same time?

Not it is not. It will only connect to 2.4GHZ or 5GHZ at one time. To get both at once on a laptop you'll need an external adapter as no one is selling true dual band in the half-mini form factor.

It will connect to either frequency, but only one at a time, of course. You can see all available connections from both bands.

It is listed as 2.4 ghz, and it's a quad processor. It's fast for a moderate priced laptop.

Only for the anntena that provides you with the 2.4 frequency you have to then get a dual band one and one that does 5.0 to answer yes only to the 2.4 ghz anntenna

This is M.2 NGFF, NOT Mini-PCIe Compare for yourself: http://www.mfactors.com/7260ngw-intel-dual-band-wireless-ac-7260-802-11ac-dual-band-2x2-wi-fi-bluetooth-4-0/ http://en.wikipedia.org/wiki/M.2

2.4 Ghz works perfectly. I don't have a 5Ghz WiFi router, so I don't know if there is any performance gain from the higher frequency, but I suspect not, assuming similar signal strengths for both.

No, of course not. One card takes up one slot, how are you going to get two in one ? It's strongly recommended you use matching ram for each slot (i.e. you could have 4 GB in one slot and 2 GB in the other for 6GB total, but it's not recommended).

Yes. I'm currently using Win 8.1 with all updates and everything is fine on 2.4 and 5 Ghz. Personal note...Don't forget to use the "WLAN" control center software that came with the dongle. It simplifies things. Also, my router is the Asus AC1900. Pricey but, worth every penny. It's a home network beast. It is able to broadcast on both bands at the same time. I had another router that said it worked on both bands. Sadly, not at the same time. Make sure your router can deliver whatever your looking for.

You can look for information at linksys It says it does run 2.4Ghz and 5 Ghz..... go to the address for more information. http://www.linksys.com/en-apac/products/routers/E2500

The wireless card is: Intel Dual Band AC 3160 802.11 A/AC/B/G/N 2.4/5.0GHz + Bluetooth 4.0 Up to 433Mbps (2x2) We will ask Amazon to update this listing.

I really haven't checked the speed of the card, but I haven't had any problems using both ports simultaneously -- no perceptible slow down with my equipment attached.

You can set up different SSIDs with each band. Obviously AC is reserved for 5ghz if you wish to use it. I have mine set up to run 2.4ghz as one SSID and 5.0 as another. Both CAN run simultaneously, but it's not required. You can run either/or without the other.

This is just the R9 290 the "X" version is 1GHz, this is 947MHz... but other than that exactly the same card.

This should be good for gaming. With good signal strength and once it connects it stays connect (at 2.4 gHz). The 5gHz connection is terrible for this card.

As I just posed, the model I just picked up at best buy has Core I7 4510 CPU and Dual Band Wireless AC. This is a newer revision as all previous models had the 7260bgn single band card.

This part definitely supports both 2.4 and 5 GHz; I'm currently using it at 5GHz. But I think I'm using 802.11n; max throughput is around 240-270 Mb/s (using Linux Mint 16 and an Intel wifi PCIe card). So I can't say about 802.11ac.

One is (probably) 300 MHZ, and the other is 310MHZ. Match to the frequency on your receiver, although either will work.

I use this on a laptop with a dual band Asus router. I have the same result as you, I see the 2.4GHz but not the 5GHZ. Seems rediculous that Asus reciever can not see Asus dual band router. On other hand it locks on to the 2.4GHz signal very well and so I am happy enough. Guess if can not detect 5Ghz from Asus router than this is not such a great product.
