I have an HP pavilion 15 model j9h21ua, and a fresh install of Debian 9. I'm very new to Debian, but I figured out how to get non-free drivers working.

Despite this, I can't seem to locate my network driver in lsusb or lspci -nn, which makes it kinda hard to figure out what drivers to install. I tried some kernel thing posted earlier, and some other driver fixes to no avail. I may try reinstalling regardless because I'm not exactly sure what I did to it, but I'd like to be able to use the wireless functionality on my laptop!

Here is the lspci -nn printout:

According to partsurfer.hp.com, it would be a Realtek RTL8188EE 802.11bg/n 1x1 WiFi adapter.

Since it's a PCIe device, it really should be visible in the lspci listing, regardless of any WiFi driver. Perhaps the ACPI firmware implements a radio kill-switch? Try pressing the F12 key, or the Fn+F12 key combination.

According to this manual, there might be a WiFi indicator light integrated into the F12 key or near it. Is it lit? Is it lit up amber, or some other (unspecified) color? Does it change if you use the above-mentioned key/combination? If you can make it change, check the lspci listing again after changing the state of the WiFi indicator light.

If that does not help, or the F12 key is unresponsive, you might need a model-specific RF-kill driver. Unfortunately, implementing such a driver might require some reverse engineering on the hardware, unless HP would kindly make the hardware programming documentation available to Linux developers.
