Network Connections Folder Empty, No Networks Devices Showing in Device manager

[TheSiscaro]

Hi to everyone, HP Pavilion Laptop 15-n273ea not showing any network adapter devices not even the LAN, you plug in the Ethernet cable and nothing shows up you look for the WLAN and it does not exist, yes both LAN and WLAN are not there anywhere, I tried another wireless card the U98H113.00 and it does not show up as well.  I tried a bit of everything’s and not able to sort it out, registry, new fresh install of windows 10 64 bit, back to windows 8.1 64 bit because I read other people got this problem after upgrading to windows 10 but even going back to windows 8.1 did not work, Networks Adapter are not for this Laptop anymore, tried the HP Assistant, nothing gives back my Networks Adapter, what's going on?  The only way to get online with this Laptop is by USB Wireless Adapter, Realtek 8811 CU and more using it on my HP Desktop it’s enough to plug it in and Windows 10 Pro 32-bit install it without any problem, when I use it in my Laptop I need to install the driver because Windows 10 Home 64-bit does not install it.  I hope someone of you can help me, thank you everyone, Filippo Siscaro.

Hi Filippo

Do the relevant Network Adapters show up in Device Manager?

Could be a hardware issue. Try running HP hardware diagnostics. See page 93 of

HP Pavilion 15 Notebook PC HP Pavilion TouchSmart 15 Notebook PC - Maintenance and Service Guide

Hope this helps

Hi, the only Network Adapter that show in device manager is the USB one I am using to get online, I am goign to try the HP hardware diagnostic as you suggest and I will let you know about it, I do think it can be hardware issue but it is strange both adapters are not working and even the new one ( used )  WLAN its not working, thank you.

Also try load setup default in BIOS, and/or updating or reflashing the BIOS.

Hi, no...tried all and no luck,  hp hardware diagnostic , bios default, windows is update, why both adapters are missing?  Strange...hardaware failure on both?   Even the WLAN used one been sold as tested and working is not good!!??

What happen if you remove wlan module, does ethernet show up in device manager?

Which wlan module was installed. Can you download driver from manufacturer website? For Intel module, I would use Intel Driver & Support Assistant to detect and install drivers.

Hi Brian, removed and nothing, no ethernet, Realtek RTL8188EE, yes I can get the driver, by the way I did upadate the BIOS as well....thank you for your help anyway
