Download Unknown Devices from: https://www.majorgeeks.com/files/details/unknown_devices.html
I recently mentioned buying my sister’s old tower which led to a problem — not enough places to plug it in on my router. I only have four ports on my router, three taken up by three other towers, and one used by my cable TV. I need my cable box hooked up to the internet for it to work. I use my old computers for backups.
I could dig out a router or switch I might have around here somewhere and chain them together but instead, I went with a USB wireless adapter. I had one problem — I couldn’t get any drivers to set up. The Device Manager was just referring to it as an 802.11n WLAN Adapter which is not very helpful without the brand name. There were no name-brand markings on the device either.
So I dug out a program that I used in the past for unknown devices conveniently called, Unknown Devices. Run it and it automatically starts scanning for all installed devices and hopefully will help identify any issues. In my case, it identified the device as a Realtek Semiconductor device but without the model number; it was still a pain to find the drivers. But still, this program has been helpful in the past when finding drivers for unknown devices.
I did finally find the proper driver to install. I just plugged the adapter into my main Asus computer and it was set up with no issues with the name Realtek RTL8192EU Wireless LAN 802.11n USB 2.0 Network Adapter.
I found a link to download the drivers here: https://www.realtek.com/en/component/zoo/category/rtl8192eu-software
This is on an older tower that was originally XP and now it has been reconnected to my network.
