My Yoga Slim 7 runs Windows 11 and has no built-in Ethernet port. I've tried two USB-to-Ethernet adapters without success. The network adapter list shows Wi-Fi and several virtual adapters, but nothing that looks like Ethernet. What should I check?
Can I get Ethernet working on a Yoga Slim 7?

First, check the exact Yoga Slim 7 model and processor. That name covers different machines, including Intel and Snapdragon models. If yours runs Windows 11 on Arm, the adapter needs a compatible Windows Arm driver. A driver for ordinary x64 Windows may not work.
Look up the adapter's exact model or chipset on its manufacturer's support page and check whether a Windows 11 Arm driver is available. You shouldn't need a special third-party tool just to add Ethernet.

Plug an adapter in and watch Device Manager. Does a new network adapter appear, or perhaps an unknown device under Other devices? The Realtek entry you listed is the Wi-Fi card, while the VPN and WAN entries are virtual adapters.
If something appears with a warning symbol, check its properties for an error and look for the correct driver. If nothing changes at all, try another USB port and, if possible, test the adapter on another computer. That helps separate a driver problem from the adapter or USB connection not being detected.

Connect to Wi-Fi if you can, then plug in the adapter and check Windows Update, including optional driver updates. Windows may find a driver that way. If it doesn't, use the adapter maker's driver for your Windows version and processor.

If Wi-Fi isn't available, USB tethering through a phone could provide a temporary connection while you check for a driver.

Once an Ethernet adapter actually shows up, check whether Windows says the cable is disconnected or whether it connects without internet. Those are different problems. Try a known working cable and another router port before assuming the laptop can't use Ethernet.

You can find the processor and system type under Settings, System, About. That should help narrow down which driver to look for.
