What do I need to be aware of to upgrade my wifi adapter to 5GHz

[ima_user]

I have the Broadband wifi adapter that came installed on my PC. It is 2.4GHz only. I would like to upgrade it to dual band to get the most out of my TP-Link AC5400 router. What should I know before I buy a new wifi adapter? I'm not afraid to install a card in the computer. Thank you.

Hi:

Open up the PC, and check if there is one or two wireless antenna cables connected to the wifi card in there now.

Here is the service manual.  The wifi card should be lying flat on the motherboard with one or two thin and delicate antenna cables going to it.

The wifi card will look something like this...

If there are two, you can upgrade to this dual band AC wifi card...

Intel Dual Band Wireless-AC 7260 802.11 ac 2x2 WiFi + BT 4.0 HP Part # 710661-001

The card is readily available on eBay or Amazon, and doesn't cost much at all.

Do your search by the HP part number, not by the model number of the wireless card.

When I looked at this wifi adapter on Amazon, it said it is intended for use in a laptop. Should it also work in my Envy 700-410xt desktop? Thanks.

Yes, it will work just fine.

They are all notebook wifi cards used in most desktop PC's made in the last several years.

But your PC must have two antenna cables for any dual band wifi card to work.
