Dual Band Wireless card?

[Jerry2356]

I am considering purchasing 

HP Pavilion 590-p0066 Desktop PC  does it have a dual band card in it?

Hi:

Yes, it does, but it is not the best dual band AC wifi card out there...Look under the networking specs.

The parts list indicates the model of the card is the WLAN - RT CHOPARD AC 1x1 (Realtek RTL 8821CE)

That card has a maximum throughput of 433 MBPS with an AC router on the 5.0 GHz wifi band, and 72 MBPS on the 2.4 GHz band.

You can't upgrade the internal card either, because there is only one antenna cable connected to it and any better dual band wifi card requires two antenna cables.
