Ubuntu – Ubuntu 18.04 No Wi-Fi Adapter Found – Realtek driver rtl8821ae

realtek-wireless

I installed a fresh copy on Ubuntu 18.04 Bionic Beaver on a desktop computer. I have a Realtek usb wifi adapter plugged in.

I am getting the following message:
Sep 13 17:14:13 data-central systemd[1]: sys-subsystem-net-devices-wlp4s0.device: Job sys-subsystem-net-devices-wlp4s0.device/start timed out.
Sep 13 17:14:13 data-central systemd[1]: Timed out waiting for device sys-subsystem-net-devices-wlp4s0.device.
— Subject: Unit sys-subsystem-net-devices-wlp4s0.device has failed
— Defined-By: systemd
— Support: http://www.ubuntu.com/support

I have been unable to find any documentation that describes my error. Can you help?

Thanks.
