# Establish a Connection With Your Lattice1 via SSH

{% hint style="success" %}
Before you start, make sure your Lattice1 is **connected to your router** either through WiFi or Ethernet. Also, make sure you can communicate with your router through your computer.
{% endhint %}

If you want to change any network configuration or run software on your Lattice's router chip, which is a very lightweight Linux environment, you can **SSH into your device** using the following steps:

1. On your Lattice screen, go to **System Preferences → Device Info.**
2. The parameters you will want to use are "**SSH Host**" and "**SSH Password**".
3. Open a terminal on your computer and type this **SSH command**: `ssh root@<SSH Host>.local` (just what you see under SSH Host without the <> marks)
4. If this is your first time, it will ask you add the **RSA key**. Type `yes` and hit enter.
5. You will be asked for the **password** - type in the `<SSH Password>` from your Lattice1 screen. Again, only the password itself, not the <> marks. Please note you might **not see your input** on this step, but type the password in and hit enter and you should be okay.
6. If successful, you will see a **welcome prompt** with Lattice1 ASCII art and information about the GCE version. This is how the whole process should look on your terminal:

Done, you can now **control your Lattice’s Linux environment**: update configurations, run whatever software you want, or just poke around under the hood.

But if you’re looking for your private keys, [**you’ll be out of luck**](https://docs.gridplus.io/lattice1/security-features)!

### Troubleshooting

{% hint style="danger" %}
If you can't ping the Lattice1 through **your router,** your router is probably not configured for **mDNS** - the protocol that allows devices to broadcast their hostname on the local router network and for the router to rebroadcast it to other devices - which allows you to search for devices with the **'.local' suffix**.

To solve this, please check your router's user manual and look for enabling mDNS.

You can still communicate with the device even **without mDNS enabled**, but you will have to use the device's **IP address** instead of the hostname - so the command `ssh root@GridPlus-xyz123.local`would become`ssh root@123.456.789.012`.
