This totally worked for me. I'd been struggling a few days with this until happening on this post.
I'm on Lubuntu 18.10 with 4.18.0-10-generic (out of the box).
Thanks Chili for spelling it out! I'm not a total newbie but more of an advanced end user, and was working on a computer I built for about $40 not including the $5 junk motherboard my 12 year old bought me at a flea market. I built the computer to show him how to build computers. Pentium 4, 2 GB RAM, and an AGP Radeon card. How old school is that?

Hey guys,
This seems like a perfect guide for an issue that took me whole day to work out. Unfortunately, my struggle is not quite done - I followed the steps here and got no errors, however I still can't actually connect to any wifi.
My networkctl displays:
even though lshw -class network seems OK:Code:IDX LINK TYPE OPERATIONAL SETUP 1 lo loopback carrier unmanaged 2 enp1s0 ether routable configured 3 wlx000f00dbbe5f wlan no-carrier configuring 4 docker0 ether no-carrier unmanaged
Finally, the relevan lsusb entry is:Code:*-network description: Ethernet interface product: NetXtreme BCM5764M Gigabit Ethernet PCIe vendor: Broadcom Inc. and subsidiaries physical id: 0 bus info: pci@0000:01:00.0 logical name: enp1s0 version: 10 serial: 00:25:b3:c8:53:43 size: 1Gbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm vpd msi pciexpress bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.137 duplex=full firmware=5764m-v3.35 ip=192.168.0.2 latency=0 link=yes multicast=yes port=twisted pair speed=1Gbit/s resources: irq:28 memory:e3000000-e300ffff *-network:0 description: Wireless interface physical id: 1 bus info: usb@2:4 logical name: wlx000f00dbbe5f serial: 00:0f:00:db:be:5f capabilities: ethernet physical wireless configuration: broadcast=yes driver=rtl8821cu multicast=yes wireless=unassociated *-network:1 description: Ethernet interface physical id: 2 logical name: docker0 serial: 02:42:87:b4:0c:a7 capabilities: ethernet physical configuration: broadcast=yes driver=bridge driverversion=2.3 firmware=N/A ip=172.17.0.1 link=no multicast=yes
I thought the issue might be in netplan config: so here is my 50-cloud-init.yaml:Code:Bus 002 Device 002: ID 0bda:c811 Realtek Semiconductor Corp.
Any ideas what else I can try?Code:network: ethernets: enp1s0: addresses: - 192.168.0.2/24 gateway4: 192.168.0.1 nameservers: addresses: - 192.168.0.1 version: 2 wifis: wlx000f00dbbe5f: dhcp4: true access-points: "ak": password: "ak123456"
