WSL 2.0 and Internet Connectivity

The Issue with Internet Connectivity:

I had initial issues connecting to the internet.

ping google.com

Turns out it was due to the incorrect DNS server listed in the /etc/resolv.conf. It isn't enough to edit the file since it is symlinked to /run/resolvconf/resolv.conf.

Choose any valid DNS Server for nameserver.

sudo rm /etc/resolv.conf
sudo bash -c 'echo "nameserver 1.1.1.1" > /etc/resolv.conf'
sudo bash -c 'echo "[network]" > /etc/wsl.conf'
sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf'
sudo chattr +i /etc/resolv.conf

WSL 2.0 Prerequisites

For x64 systems: Version 1903 or higher, with Build 18362 or higher.
For ARM64 systems: Version 2004 or higher, with Build 19041 or higher.
Builds lower than 18362 do not support WSL 2. Use the Windows Update Assistant to update your version of Windows.

You can determine the version via command prompt:

ver

or Powershell

[System.Environment]::OSVersion.Version

Just follow the instructions here.
