IF no antenna, can i install WWAN card?

[waterant]

As described in topic, i have added one intel xmm 7560 WWAN card into my HP zbook 15 firefly G7 and have driver installed, and works fine. but i met 2 issues:

1. there's no antenna could be found around the place of WWAN.

2. When i insert a sim card, the ISP's logo could appear but "no service" displayed. 

i think no antenna cause no signal. 

can anybody tell me how to resolve those 2 issues? thanks!

Hi:

The only way to resolve both problems would be to install the required wifi antenna wires that will provide wireless reception to the WAN card.

That will require an extensive amount of work including figuring out where to buy the antenna cables and it appears that you would have to buy a different back cover, because the back cover for models that came with a WWAN card have a different back cover--probably so the additional antenna transceivers can be properly fitted.

Chapter 3 of the service manual has the antenna kit needed and back cover.

Maintenance and Service Guide (hp.com)

Chapter 6 of the service manual has the removal and replacement procedures.

If it were me, I would buy a USB adapter to fit your Intel WWAN card in and connect that way.

But you would have to find one that has 4 antenna wires for proper reception.

The other thing you can do would be to trade in your notebook and buy the model that has a WWAN card included.
