How to access the AltoPlex WebUI for the first time

By default, AltoPlex radios use dynamic IP address assignment and, beginning with release 3.6.0, have a factory default fallback static IP address of 192.168.0.1.

Additionally:

  • Radios can be configured to use a static IP address, rather than dynamic IP address assignment. This will override the fallback IP unless the radio is factory reset. After a factory reset, it will return to default behavior.
  • Radios upgraded to release 3.6.0 that have not been factory reset will have a factory default fallback IP address of 192.168.0.51, unless they have a configured static IP address that overrides the default address. After a factory reset, they will have the default behavior.
  • Radios at a release earlier than 3.6.0 have a unique factory default IP address that is printed on the label affixed to the front of the radio at manufacturing time.

    You can determine if your radio was manufactured before release 3.6.0 based on the IP address printed on the label on the front of the radio:

    • If the radio was manufactured before the release of 3.6.0, the IP address on the label will be a unique IP address.
    • If the radio was manufactured after the release of 3.6.0, it will either not have an IP address on the label, or the IP address will be 192.168.0.1.

Because AltoPlex radios participate in multicast DNS (mDNS), computers that support mDNS and are on the same subnet as the radio can connect to the radio by using its hostname. In general, this should work regardless of whether the radio is configured to use dynamic or static addressing, or if it is using the fallback default IP.

For example, if your radio's hostname is KB-C7-00-01 and your computer is on the same subnet as the radio, you can access the WebUI by typing https://KB-C7-00-01 (or https://KB-C7-00-01.local) into your browser's URL address bar:

Use the factory default fall-back IP address to connect to the radio

This section applies to radios with firmware version 3.6.0 or newer. Radios with older firmware have a unique fallback link local IP address that was provided on a printed label when the device was manufactured. For devices originally manufactured with a software version prior to 3.6.0 and then upgraded to release 3.6.0 or newer, the default IP address will depend on whether the device has been factory reset since the upgrade:

  • If the device has not been factory reset, the default IP address is 192.168.0.51.
  • If the device has been factory reset, the default IP address is 192.168.0.1.

To connect to an AltoPlex radio by using its default fallback IP address:

  1. Configure your computer to be a member of the 192.168.0.x subnet.

    For example, on Windows 11:

    1. Click the Windows icon.
    2. Click Settings.
    3. Click Network & internet.
    4. Click Ethernet.
    5. For IP assignment, click Edit.
    6. Select Manual.
    7. Click to toggle on IPv4.
    8. For IP address, type an address in the 192.168.0.x subnet (for example, 192.168.0.2).
    9. For Subnet mask, type 255.255.255.0.
    10. Click Save.
  2. Next, either:
    • Plug your computer's Ethernet connection into the LAN port of a PoE injector that is connected to the radio.

      The LAN port is sometimes labeled as the Data out port, the Out port, or something similar.

    • Plug both your computer and the radio into a PoE switch.

      To access the radio by using the default IP address, make sure that the switch is not connected to the backhaul network or that the backhaul network does not have a DHCP server running on it.

  3. Access the radio's WebUI by entering either the hostname (for example, https://KB-C7-00-01) or the default IP address (https://192.168.0.1) in the address bar of a web browser.

    If a radio has a configured static IP address that is different than the default address, the configured IP address must be used to access the radio.

  4. A warning message may indicate that the self-signed certificate used by the device is not recognized by the browser. Instructions to clear the message vary depending on the browser. For example, in Chrome:
    1. Click Advanced.
    2. Click Proceed to…

The WebUI will open with the Status tab displayed.

Determine the IP address of a radio by using mDNS

If you configure a radio to use a static IP address and subsequently do not remember the IP address, you can use mDNS commands to determine the radio's IP address.

This requires that your computer supports mDNS and is on the same subnet as the radio.

  • Windows Powershell:

    Resolve-DnsName <hostname>

  • MacOS:

    dns-sd -G v4v6 <hostname>

  • Linux:

    avahi-resolve-host-name -4 <hostname>.local

where <hostname> is the hostname of the AltoPlex radio (KB-XX-XX-XX).

Access the radio by using the management Wi-Fi access point

AltoPlex radios also provide a mechanism to access all radios through a management Wi-Fi access point, which is enabled by default but can be disabled. See Wi-Fi connection to a AltoPlex radio for more information.
