HP website does not disclose the technical details about the wi-fi card on dv6tqe. Can anyone tell me about its antenna config, i.e. 2x2 or 1x1?
I looked up that particular config (dv6t) you linked to at HP PartSurfer, it shows it to have been built with a "802.11bgn Int HMC 1x2 RP WLAN"
I don't guarantee this is what you will get, HP can change hardware specs at any time but they should also change the Product Number (A1T70UA) when they do, so be sure the one you order is the same product number as the one researched on PartSurfer.
Product number is different than Model number on HP notebooks, Product Number will reflect the hardware used to build that particular Model of notebook when using PartSurfer.
