Solved Ethernet Controller - PCI bus 4 (Code 28)

[Trajado]

Hello,

I've bought a TP-Link USB Wireless Adapter (Model: TL-WN722N) and I can't seem to make it work.

I have updated every driver on the pc except that Ethernet Controller - PCI bus 4, that i can't seem to figure out what it is.

At this point I'm not even sure what the problem really is, because i can get connection by ethernet cable on the desktop and i can make the Adapter to work on my Laptop.

A friend told me that apparently my PC already had a wireless adapter i just needed the antena, so i used one of his and still nothing.

Maybe something is in conflict, i don't know.

I saw on another thread that this might help:

-Other Devices
---Ethernet Controller
-----Details: Device Instance Path:
-------PCI\VEN_168C&DEV_001C&SUBSYS_1033147B&REV_01\4&132A9A3C&0&00E3

Thank you all in advance.

Let's start by addressing one thing at a time.

I have updated every driver on the pc except that Ethernet Controller - PCI bus 4, that i can't seem to figure out what it is.

Is that the PC with the "Other Device" info you showed at bottom of your post?

What's the make/model of the computer or motherboard with the "Ethernet Controller" problem you mention? On that specific machine:
