Hello everyone my hp 250 g3 notebook does not connect to wifi and there is no wifi card in the device management network cards. I disassembled the notebook and the card is burnt out. Is it possible to replace the original card "Ralink RT3290" with another model? Could there be bios compatibility issues? What models do you suggest? Thanks in advance for the suggestions. HP 250 G3

If your notebook has two wifi antenna cables connected to the Ralink wifi card, you should be able to upgrade to either of these models...
Dual band AC:
Broadcom BCM4352 802.11ac 2x2 Wi-Fi + Bluetooth 4.0 combo HP part #724935-001
Dual Band N:
Broadcom BCM943228HMB 802.11 a/b/g/n 2x2 Wi-Fi + Bluetooth 4.0 combo HP part # 730668-001
You should be able to find either card on eBay, maybe Amazon too.
Search by the HP part number, not the model of the wifi card.
Below is the link to the service manual...

and thanks for the reply
my notebook only has one wi-fi cable
this means that I cannot use dualband cards
from the manual I read that I could use in addition to a new one
- Ralink RT3290LE 802.11bgn 1x1 Wi-Fi and Bluetooth 4.0 Combo Adapter part #690020-001
- Realtek RT8723BE 802.11bgn 1x1 Wi-Fi + BT4.0 Combo Adapter part #753077-001
- Atheros AR9565 802.11bgn + Bluetooth 4.0 Wi-Fi Adapter part #733476-001
or cards without bluetooth
- Realtek RTL8188EE 802.11bgn Wi-Fi Adapter part #709848-001
- Atheros AR9485 802.11b/g/n 1x1 WiFi Adapter part #675794-001
Are these all wi-fi cards compatible with my notebook?
Thanks again for the availability

You're very welcome.
Yes, unfortunately, you are stuck with a single band wifi card.
I would get the Realtek RT8723BE 802.11bgn 1x1 Wi-Fi + BT4.0 Combo Adapter part #753077-001
That is because it is the only wifi card that was really designed to work with only one antenna cable.
If you look at the picture of that part number, there is only one terminal to connect the antenna cable to.
All the other models have two.

I see plenty of them for sale on the US eBay site.
Find a seller that ships to Italy...
