New WLAN Card Halfway Working

[jcsnider]

Hi all,

I am a fairly happy owner of Lenovo's 3rd Gen X1 Carbon.

This machine was shipped with an Intel AC7265 NGFF card.

I recently bought two different WLAN cards to replace that Intel one.
Specifically the Dell DW1560
and the Lenovo equalivant PN-20020480

Both of those cards are Broadcom which is why I wanted them to begin with and both of them have the same exact problem. (They are unable to find wireless networks, and may not be able to handle any data received in Windows)

• 
  ■In Windows, both devices were detected as new hardware and the appropriate drivers will downloaded and installed over ethernet.
  ■The bluetooth component in both of these cards works fine.
  ■Wifi drivers will install but afterward it never scans or always fails to locate any networks around it.
  ■On both of these cards, I can create an adhoc network. Nothing can connect to it though.

To me it seems like they can broadcast fine, but not process anything it reads/receives.

I have tried a wide array of drivers but none of them have worked any better. I know for a fact that the cards are good. I also know for a fact that they will work in this machine. (Works perfectly fine in my OSX environment)

Any idea on why this may not work in Windows? Any tips on how I should go about debugging?

Thanks,
JC

You said the "appropriate drivers will downloaded [sic] and installed [sic] over ethernet.

Meaning you used the physical ethernet port on the laptop or a USB ethernet adapter connected to a router, modem, ISP, internet - correct?

Did you disable that wired port (which ever you used) and enable the WLAN card that was installed?

Also, I would re-visit the ad-hoc network setup:

May have overlooked something....

Hi Ralston, thanks for taking an interest in this.

I used a physcial ethernet port to connect to the router in order to obtain drivers, I have that available at any time.

My problem is not necessarily with my adhoc config, I only over tried that to see if I could use the card to broadcast an SSID.

The real problem is that I am unable to detect or connect to any networks while in Windows or even Linux which is very strange because like I said, it works in an OSX environment on the same machine perfectly fine. (Not a bios issue, the problem exists somewhere in the OS or driver spectrum)

Nothing obvious comes to mind.

What I would do is reinstall the original card and get things running. Then scan the registry for references to that card. Make note of those references and settings.

Swap in one of the other cards and repeat. Could be that some obscure setting is not getting reconfigured for the new card(s). A setting still shows up "old card" versus "new card" when the various registry entries are compared. Could be some cryptic difference....

Tedious but generally other things will be learned so there is some value (at least in my mind) in doing such things.

Certainly clear that you know what you are doing so there is even a greater chance that you will note something out of expectations.
