Intel Dual Band Wireless-AC 3160 or 7265?

[Sublix]

Good morning everyone, I want to upgrade the wifi adapter in my HP Pavilion 17-g178ca laptop, however, within the Maintenance and Service Guide, there is conflicting information.

Guide:

http://h10032.www1.hp.com/ctg/Manual/c04655191

I want a Dual band wifi adapter, the manual shows the part as being  784644-005 (Intel Dual Band Wireless-AC 7265 802.11 ac 2x2 WiFi + BT 4.0 Combo Adapter (non vPRO)) but searches online for that exact part number always return with a different model Wifi adapter (Intel Dual Band Wireless-AC 3160 802.11 ac 1x1 WiFi + BT 4.0 Combo Adapter)

Which one should I be getting? Thanks in advance to anyone who can clear things up for me!

That is what I am seeing , too. The part number is a 3160, which is not a bad wireless card but is not as good as a 7265.

I believe the reference in the Manual to a 7265 card is a typo. 

Here is the Manual:

See p. 38 for "how to". 

If your laptop was fitted from the factory with any wireless card other than the Intel, you only have a single antenna and upgrading to any dual band card will be next to impossible. However, your specs seem to say you already have the 3160 card which includes 2 antennae. Also, your laptop has no whitelist so you are not limited to using one of the HP part number cards. 

You can therefore install this card and it will work:
