Unboxing and Initial Setup

Before we jump into the nitty-gritty, let's make sure we have everything we need and get the basics covered.

What's in the Box?

Inside the box, you should find:

  • The MikroTik SXT Lite5 unit itself.
  • A PoE (Power over Ethernet) injector.
  • A power adapter for the PoE injector.
  • A mounting bracket and some screws.

Connecting the Hardware

  1. Connect the Ethernet Cable: Plug one end of an Ethernet cable into the Ethernet port on the SXT Lite5. This is your data and power connection.
  2. Connect to the PoE Injector: Plug the other end of the Ethernet cable into the port labeled "PoE" on the PoE injector.
  3. Power Up: Connect the power adapter to the PoE injector and plug it into a power outlet. The SXT Lite5 should now power on. You'll typically see some LEDs light up indicating it's receiving power. This is a crucial step, guys, so double-check everything is connected securely.
  4. Connect to Your Computer: Use another Ethernet cable to connect the port labeled "LAN" on the PoE injector to your computer. This will allow you to access the SXT Lite5's configuration interface. Make sure your computer's Ethernet adapter is enabled.

Initial Access

Now that everything is connected, let's access the SXT Lite5's configuration.

  • Download WinBox: The easiest way to configure MikroTik devices is by using WinBox, a free GUI-based tool. You can download it from the MikroTik website (www.mikrotik.com). Look for the "Downloads" section and find the WinBox executable.
  • Run WinBox: Once downloaded, run WinBox. It doesn't require installation; it's a standalone executable.
  • Find Your Device: WinBox will scan your network for MikroTik devices. You should see the SXT Lite5 listed with its MAC address. If it doesn't show up, make sure your computer's Ethernet adapter is set to obtain an IP address automatically (DHCP). Sometimes, manually setting your computer's IP address to be in the same subnet as the SXT Lite5 (usually 192.168.88.x) can help.
  • Connect: Click on the MAC address of the SXT Lite5 and then click the "Connect" button. If this is the first time you are connecting, it will prompt you for a username and password. The default username is "admin" and there is no password. Leave the password field blank and click "Connect".

Basic Configuration

Okay, we're in! Now, let's get the SXT Lite5 configured for your specific needs. We'll cover the most common scenarios: setting it up as a wireless access point (AP) or as a wireless station (client).

Setting up as an Access Point (AP)

If you want the SXT Lite5 to act as a base station, providing wireless connectivity to other devices, follow these steps:

  1. Wireless Configuration:
    • Go to "Wireless" in the WinBox menu.
    • You should see a wireless interface (usually wlan1). Double-click on it to open its settings.
    • Mode: Change the "Mode" to "ap bridge". This tells the SXT Lite5 to operate as an access point.
    • Band: Choose the appropriate frequency band. Since it's the Lite5, you'll likely be using the 5 GHz band. Select a band that matches the capabilities of your client devices (e.g., 5GHz-only, or 2GHz/5GHz if you want dual-band support).
    • Channel Width: Select a channel width. 20MHz is generally a safe choice for compatibility, but you can experiment with wider channels (40MHz, 80MHz) for higher throughput if your environment is relatively free of interference. Keep in mind that wider channels can be more susceptible to interference.
    • Frequency: Choose a frequency channel. Use the "scan" button to see which channels are least congested in your area. Selecting a less crowded channel will improve performance.
    • SSID: This is the name of your wireless network. Enter a descriptive SSID that users will see when they scan for available Wi-Fi networks.
    • Security Profile: Click the dropdown and select "default" if you want to use the default security settings. Otherwise, you may want to create a new Security Profile to configure a strong password. For better security it is highly recommended to create a new security profile with WPA2 AES.
    • Click "Apply" and then "OK".
  2. IP Address Configuration:
    • Go to "IP" -> "Addresses".
    • Click the "+" button to add a new IP address.
    • Address: Enter an IP address for the SXT Lite5 on your network. For example, if your network uses the 192.168.1.0/24 subnet, you could assign the SXT Lite5 the address 192.168.1.2. Make sure this IP address is not already in use on your network.
    • Interface: Select the wireless interface (wlan1) from the dropdown.
    • Click "Apply" and then "OK".
  3. DHCP Server (Optional):
    • If you want the SXT Lite5 to automatically assign IP addresses to devices that connect to its wireless network, you'll need to set up a DHCP server.
    • Go to "IP" -> "DHCP Server".
    • Click the "DHCP Setup" button.
    • Select the wireless interface (wlan1) from the dropdown and click "Next".
    • Follow the wizard to configure the DHCP server settings, such as the IP address range and the default gateway. Typically, you'll want the DHCP server to assign IP addresses in the same subnet as the SXT Lite5's IP address (e.g., 192.168.1.100-192.168.1.200 if the SXT Lite5 has the IP address 192.168.1.2).
    • Click "Next" through the remaining steps and then click "OK".

Setting up as a Station (Client)

If you want the SXT Lite5 to connect to an existing wireless network, follow these steps:

  1. Wireless Configuration:
    • Go to "Wireless" in the WinBox menu.
    • Double-click on the wireless interface (wlan1) to open its settings.
    • Mode: Change the "Mode" to "station bridge". This tells the SXT Lite5 to operate as a client.
    • Band: Choose the appropriate frequency band, matching the access point you're connecting to.
    • Frequency: You can either manually specify the frequency of the access point or use the "scan" button to scan for available networks.
    • SSID: If you know the SSID of the access point, enter it here. If you used the "scan" button, select the network from the list.
    • Security Profile: Select the appropriate security profile, matching the security settings of the access point. If the access point uses WPA2-PSK with AES encryption, select a security profile with those settings and enter the correct password.
    • Click "Apply" and then "OK".
  2. IP Address Configuration:
    • Go to "IP" -> "Addresses".
    • If your network has a DHCP server, you can leave the SXT Lite5's IP address configuration as is (it will obtain an IP address automatically). Otherwise, you will need to manually configure a static IP address.
    • To set a static IP address, click the "+" button to add a new IP address.
    • Address: Enter an IP address for the SXT Lite5 on your network. Make sure this IP address is in the same subnet as the access point and that it is not already in use.
    • Interface: Select the wireless interface (wlan1) from the dropdown.
    • Click "Apply" and then "OK".
  3. Gateway Configuration (if using a static IP address):
    • Go to "IP" -> "Routes".
    • Click the "+" button to add a new route.
    • Dst. Address: Enter 0.0.0.0/0 (this represents the default route).
    • Gateway: Enter the IP address of your network's gateway (usually your router's IP address).
    • Click "Apply" and then "OK".
