# Network & Wi-Fi

This guide explains how to set up the local network in your classroom. The goal is to create a stable network where one computer acts as a server to provide Wi-Fi for all other client machines.

CRITICAL SETUP RULES

1. ONE SERVER ONLY: You can only have one computer set as a `server` on the network. Multiple servers will cause the network to fail.
2. SERVER USES CABLE: The server machine must not use Wi-Fi. It must connect to the router using a Ethernet Cable .

### Phase 1: Setting up Cables & Hardware

This part involves connecting the server and routers together.

### 1. Choose and Connect the Server

Select one computer to be the server. This should be your fastest machine with an Ethernet port. Connect this server directly to your main router using a Ethernet Cable .

### 2. Place and Connect Routers

- One Router: Place it in the middle of the room for best Wi-Fi signal.
- Two Routers: If you have a second router, connect it to the first one with a cable. Place them as far apart as possible.

### 3. Connect Other Computers with Cables (Best)

Whenever possible, connect clients computers to a router using a Ethernet Cable . This is much faster and more reliable than Wi-Fi.

### Phase 2: Software Setup

This part involves setting up the Role on each computer using the `tl-sys-configure` tool.

### 1. Set up the Server

On the main server machine, run `tl-sys-configure` and set its Role to `server`.

Caution

Double-check that no other computer is set as a `server`.

### 2. Set up the Clients

On each client machine, run `tl-sys-configure` and do the following:

1. Set the Role: Set the Role to `client`.
2. Set the Wi-Fi Name: Set the SSID (Wi-Fi name) to match the network you want clients to use.

Tip: Spreading the Load

If you have multiple routers, try to spread clients across them.

- One Router: All clients connect to the same Wi-Fi name ( SSID ).
- Two Routers: Set half the clients to the first Wi-Fi name, and half to the second Wi-Fi name.

### 3. Turn off Wi-Fi on Wired Machines

On any computer connected with a cable (including the server), turn off the Wi-Fi. You can use the network icon at the bottom of the screen to do this.

Important

Always make sure the server has Wi-Fi turned off.
