Wireless Network Card Not Recognized (Yoga 3 Pro)

I had been experiencing weak/intermittent wireless connections with the Broadcom network card that shipped with the system (Yoga 3 Pro 1370).  This morning I switched it out for an Intel 7265NGW -- but upon restart no NIC card was detected at all.  Not in system tray and not in Device Manager.  I updated BIOS to A6CN58WW and installed all Intel drivers -- but nothing, card not recognized.  No error messages or rejection etc. -- just not showing that I have a wireless adapter at all.  When nothing worked, I switched back to the Broadcom card -- but now this card is not recognized either.  I used System Restore to roll back to last week, but no luck, no wireless card is being detected/recognized.  Anyone have any ideas/suggestions?  Much appreciated!

I own one of those machines and I repair computers.  I have replaced 3 of those cards (mine and 2 others) where the cards just died.  My guess is that you need a card.

Thanks -- but it is highly unlikely that both the new card was DOA and the old card died immediately at the same time.  There is something going on, either in motherboard hardware or in BIOS or other settings that is leading to system not even recognizing that a card is inserted in the slot.  Any thoughts appreciated.

Hi xrabi, 

I would just like to asked the wifi card you purchased does it have the part number SW10A11522 from the Lenovo parts list? Lenovo has a white list of wifi card tested for each model. You can get this info from the laptop's Hardware Maintenance Manual on page 55. 

Hope this helps. 

Cheers,

Re: Wireless Network Card Not Recognized (Yoga 3 Pro)

Thanks -- it does have the Lenovo FRU.  My understanding is that even if you put a non-white listed card in there, it will be recognized by the system and you will get a network card error message of some type.  In my case, it simply doesn't detect/recognize/acknowledge that there is a card there at all.  The fact that it now doesn't recognize the OEM Broadcom card when I stick it back in there makes my think either motherboard connections are now loose or something in the new BIOS is causing this.  Appreciated.

Hi, 

 

Have you tried doing loading BIOS setup defaults? Then try toggling Wireless LAN in bios.

Looking in the device manager, are there and problem devices?

 

One basic question, there is a setting in the BIOS to enable or disable wireless networking.  Is it enabled?
