Hi jlewis40,

 

Greetings.

 

Initially try to system restore to the machine to a previous working restore point/date.

 

Else, uninstall the driver from device manager ensuring that everything would be deleted.

Temporarily connect via ethernet cable to download the drivers from the support website here (Networking WLAN) to install and restart. Check if the wifi detection can be restored.

 

If same issue, proceed with the recommended steps here.

 

Update us how it goes.

 

Regards

Hi spidey101,

 

I have tried using this *Qualcomm network adapter and it does not match with my laptops *Broadcom network adapter.

 

Attached is the message I received after installation. (Problem1_No Appropriate Driver to be Installed) and Broadcom network driver details. Where can I download this specific Broadcom network driver? I have attached a screenshot of the hardware id.

Hi jlewis40,

 

Greetings.

 

Hardware ID 14E4 does indicate driver provider as Broadcom.

Checking in the WLAN shows part number 00JT470 FRU Liteon NFA335 WB335 1x1bgn+BT4.0 M.2 Combo V2.

 

Try to first download the recommended driver in your desktop for later installation.

Proceed uninstalling the WLAN driver in device manager, make sure that you place a check mark on the box to fully remove the previous driver if the rollback option is not longer available.

 

As you restart it Windows would most likely assign a built in driver from Windows so that you can check if it works for you.

If not try to go back to device manager and see if update driver option to browse in the computer with available listed driver if available to try.

 

Then third option is again to try the previously downloaded driver from the desktop and restart.

 

Let see how it goes.

 

Regards

Thanks. 

 

This slim laptop does not have an ethernet port for an RJ45 LAN connection. Can you suggest a USB network adapter (RJ45) for this laptop with specifications.

Hi jlewis40

 

It would be hard to suggest a compatible ethernet usb adapter for the USB 3.0 connection depending on the availability in your location but what I usually do is having the laptop with you during purchase.

 

Sales personnel would be testing the adapter itself so functionality and compatibility would be tested as well.

OK thanks for the tip. 

 

I was advised to disable the following under Network Adapters:

 

WAN Miniport (IKEv2)

WAN Miniport (IP)

WAN Miniport (IPv6)

WAN Miniport (L2TP)

WAN Miniport (Network Monitor)

WAN Miniport (PPPOE)

WAN Miniport (PPTP)

WAN Miniport (SSTP)

 

Could you tell me if these are necessary? If so, how to I enabled these again? The enable button isn't toggling at all on each properties device. 

 

Wifi is working good now. When I do a system recovery pressing NOVO do I get factory defaults OS and driver's installed?

Hi jlewis40,

 

There was previous reported bugs with WAN enabled that conflicts with wifi connection which MS already sent a patch before. You may review more about it here for re enabling it but if you do not use wide area network connection then you can just keep it as is since all is working ok. 

 

OKR is a factory reset features that send the machine back to out of the box setting with both Windows and drivers but make sure you back up your personal files first if you decide to use it.

Does the above mentioned WAN Miniports have any use for an USB to LAN cable connection (Network adapter)?

Hi jlewis40,

 

Greetings.

 

Most likely if you have tried it yourself there won't be any problems since you are not being connected via PPPoE unlike those days when we have dial up for a DSL service.
