HS wifi card or motherboard?

I have a HP dv6243eu, and for over a week, I have problems with my wireless card not working. In addition I found more in the device manager. I try to reinstall the drivers in Windows and I'm running out of ideas.

I read on forums that several people had the same problem as me, their solution was to return their PC to HP but they are under warranty. Me my warranty is over for a year. HP solution was changing the motherboard.

I wanted to know if there was a way of knowing if it was just the wireless card (and the change would solve the problem) or if it was the motherboard that was defective?

Thank you in advance for your response and your help!

You can find even more in the device manager.
if you checked the record of your motherboard with the WIFI was not damaged? or full of dust?
At worst, changes form there are usually multiple.

Try to make you pay WIFI card, if you're walking his buys one (prices are very affordable), otherwise it's probably the motherboard.

Thank you for your answer, I'll try that

Is that the wifi is built into the motherboard? or is it a pci wireless card?

How I made the difference?
I dare not open my PC too, I have two accesses (one for SD and another for barettes RAM) but none to my wireless card directly. This is not a bit risky?

I have a small question:
Wifi card integrated into the motherboard = impossible to change?
= Wifi PCI card can change?

Yes , you have a laptop necessarily the WiFi card is integrated into the motherboard, such as graphics cards in general. So you can not change it, you will need to purchase external WiFi card.
