+## WSL Troubleshooting
+
+If you've encountered this error on WSL-2:
+
+  ```sh
+  curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.2/install.sh | bash
+  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

+  ```
+
+It may be due to your antivirus, VPN, or other reasons.
+
+Where you can `ping 8.8.8.8` while you can't `ping google.com`
+
+
+This could simply be solved by running this in your root directory:
+
+  ```sh
+  sudo rm /etc/resolv.conf
+  sudo bash -c 'echo "nameserver 8.8.8.8" > /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
+  ```
+
+This deletes your `resolve.conf` file thats automatically generated when u run WSL, creates a new file and puts `nameserver 8.8.8.8`, then creates a `wsl.conf` file and adds `[network]` and `generateResolveConf = false` to prevent auto generation of that file.
+
+You can check the contents of the file by running:
+
+  ```sh
+  cat /etc/resolv.conf
+  ```
