Below are commands that you can use to connect and check the status of your WiFi connection using nmcli.
I usually use this when connecting my Rock Pi running Ubuntu to the WiFi Network. But commands below will also work as long as you have the nmcli in your Linux System.
Turn On WiFi
# Turn on WiFi
nmcli r wifi onScan WiFi Networks
# Scan WiFi Networks
nmcli dev wifiIf you are using multiple user accounts in your Windows computer and have installed Windows Subsystem for Linux (WSL) in one of your users, when you try to run WSL in another account you will encounter the WSL has no installed distributions error.

If you are studying Kubernetes and having a hard time running Minikube on an EC2 Instance, you are not alone. I had a hard time doing it when it was my first time.
Below are the steps (and some comments) that I took to help me run Minikube on my EC2 Instance.
| AMI | Ubuntu Server 18.04 LTS (HVM), SSD Volume Type |
| Instance Type | t3.micro (2 vCPU, 1GB Memory) |
| Storage | 8 GB (gp2) |
| Tags | – Key: Name – Value: Minikube |
| Security Group | Name: Minikube Security Group – SSH, 0.0.0.0/0Later we will be editing this. |
| Key Pair | Create your own keypair. You will need this to SSH to your EC2 Instance |
Update: I changed the Instance Type from t2.micro (1 vCPU) to t3.micro (2 vCPU). An update to Minikube required a minimum of 2 vCPUs. The error when running with t2.micro was Requested cpu count 1 is less than the minimum allowed of 2.
t3.micro is no longer in the Free Tier, make sure to stop or terminate the instance after you are done testing to avoid a huge AWS bill.
Thank you to everyone in the comments section who pointed this change.
