WWAN card for Latitude e5470

Solid black and solid white are usually for Wi-Fi.

Solid gray with black trace and solid gray with white trace are usually for WWAN.

The drivers for your laptop show it uses the DW5811e. If in the US48 then Dell P/N 3P10Y available at Walmart (only 1 left) should work and it uses the current 97FX1 driver package for Windows 10. You’ll also want to download and install the Sierra Wireless Connection Manager, Skylight.

I just checked them again and noticed that both white and black wires have a grey trace on them. I really hope they are intended for WWAN.

Since I'm not in the US, but in Romania, my options are: DW5811e (as recommended by you too) from ebay or aliexpress for about 30 USD (+shipping) and DW5809e also from ebay, but much cheaper at 15 USD (+ 4 USD for shipping). I know it has a lower max speed at 100 mbps vs 300 mbps, but It's enough for me. I found a driver package on the Dell website, I hope it works.

On Dell systems most of the time the Gray/White and the Gray/Black are WWAN. "Panasonic is different!!!"

The Brown cable is for your WiGig option if installed.

Based on what you’ve said, it sounds like they are the WWAN card’s antenna cables. I don’t see a listing for the DW5809e and will reserve comment. As noted, if in the US48, the 3P10Y card should work with the 97FX1 driver. I have no idea how this combination will react in other regions of the world.

As I mentioned earlier, I am from Romania, not the USA.

I went ahead and ordered the DW5809e card from eBay, and I shoud receive it in a few days. I will test it on my laptop and come back here with the result. I hope it works and maybe others will be helped by this. If not, then maybe I'll also try the 3P10Y variant.

I'll be back in 1-2 days.

I haven't received my order yet, but in the meantime I was gathering some more information and I stumbled upon a new option. The chinese on Aliexpress sell the EM7455 DW5811e 3P10Y ------- with included antennas. They seem to look like the factory ones, and for somebody that desparately needs a WWAN card but doesn't have the necessary antennas wired behind the LCD screen, I guess you can always fix them on the outside of the laptop casing.

I received my DW5809 WWAN card today, but something prevents the driver to install successfully.

The card has EM7305 written on it and I tried several driver versions from the Sierra website. I also tried the drivers from Dell Support website (DW5809e "Customer Kit Module") for my Windows 7 32 bit, but in absolutely every case the driver installs but the system notification shows "driver was not successfully installed".

Any ideas on how to solve this ?

Most everything associated with Windows 7 and mobile broadband did so with cooperation of computer and mobile broadband OEMs, cellular providers, and Microsoft. Then the iPhone and the Windows Phone changed the scope. By the time Windows 10 came out it was clear that cellular providers were no longer interested in the Windows Phone, Microsoft, and mobile broadband. If you bought the computer with mobile broadband and Windows 7, you might be able to continue to make that original combination work, but buying a mobile broadband card manufactured long after Windows 7 came out for use with Windows 7 will be plagued with problems. Your best bet is Windows 10, it seems to go out of its way to make modern mobile broadband cards work. If you have an account with Sierra Wireless then search their forum, the EM7305 is an older card so it seems likely their forum users have discussed its use with Windows 7.
