Advice to replace the network card on the HP Envy 15

[ziobillo]

Hi everyone,

I just signed a contract with Fastweb for the optical fiber 200 mega-bit, I have noticed that the network card installed into my notebook does not support 5GHz networks, so I would replace it with one that supports that frequency.

I wanted an advice about it, who can recommend some network card for my notebook?

The model of my notebook is a 15-hp envy k203nl and installs a network card Broadcom bcm43142.

I thank those who want to advise me.

There is good news and not so good news. Good news is you can use any wireless card that is the correct shape and size (form factor) but don't get excited yet. 

Not so good news. See page 56 of the Manual. First thing: replacement of the wireless card is a major undertaking. It requires a lot of disassembly. Second problem: your laptop probably only has a single wireless antenna. You can see on p. 56 the one dual band card offered by HP is only on the 17-inch models not the 15 inch like yours. Only the 1 x 1 Broadcom and Atheros bgn cards are offered on the 15 inch. 1 x 1 does not necessarily mean it only has one antenna but only a 1 x 1 card can work at all with just one antenna. So to even tell for sure what you have you have to open up the laptop. Assuming you have 2 antenna cables we can advise you on an upgrade to a card that will work in the 5 ghz band. 

This is the card you have.

This is a mini-pcie form factor and if you have 2 antenna this would be the card to get:
