Ping Computer WiFi (RB4011 Routing) Troubleshooting: WOL Phone Connection Issues
If you have recently acquired a new network switch (Mikrotik RB4011) and noticed that your WOL (Wake-on-LAN) phone is no longer able to turn on your PC, while the phone remains able to connect to the WiFi router (Eero access point), then this article is for you. This article will cover key concepts, provide detailed context on the topic, and include subtitles using H2, H3, and other tags. Paragraphs will be wrapped using
tags. The content inside code blocks will be properly formatted according to the programming language, including indentation and tabulation when needed.
Understanding Wake-on-LAN (WOL)
Wake-on-LAN is a technology that allows a network-connected device to be turned on remotely. This is achieved by sending a special Magic Packet over the network to the target device's network interface card (NIC). The NIC then wakes up the device from its power-saving state or turns it on completely.
Mikrotik RB4011 Switch Configuration
By default, the Mikrotik RB4011 switch disables some features, such as port mirroring and IGMP snooping. These features must be enabled for WOL to work correctly. Here are the steps to enable these features:
- Log in to the Mikrotik RB4011 switch's web interface.
- Navigate to
/ip service and ensure that the igmp-snooping feature is enabled.
- Navigate to
/interface ethernet switch port and select the appropriate port used by the Eero access point. Ensure that the following settings are enabled:
learningforwardingvlan-mode: enabledvlan-protocol: dot1q
- Create a new VLAN for the WOL traffic. In this example, we will use VLAN ID 255:
/interface vlan
add name=wol vlan-id=255
- Assign the Eero access point's port to the WOL VLAN:
/interface ethernet switch port
set [ find name=Eero-AP ] vlan-members=wol
- Configure the switch port for port mirroring, so that all WOL traffic is forwarded to the PC:
/interface ethernet switch port
set [ find name=Eero-AP ] mirrors=enabled mirrored-port=[ find name=PC-port ]
Eero Router Configuration
No specific configuration is required on the Eero router since it already forwards all multicast traffic. However, if you are using VLANs, make sure that the Eero router is correctly configured to handle the VLANs.
WOL Phone Configuration
Ensure that your WOL phone application is configured to send the Magic Packet to the PC's IP address within the WOL VLAN:
- PC IP address:
192.168.255.X
- Subnet mask:
255.255.255.0
- MAC address:
YY-YY-YY-YY-YY-YY
Troubleshooting
If the WOL operation still fails, check the following:
- PC power-saving settings are configured correctly.
- WOL is enabled in the PC's BIOS.
- WOL is enabled in the PC's network adapter settings.
- The firewall on the Mikrotik RB4011 is not blocking multicast traffic.
- This article provided guidance on setting up Wake-on-LAN (WOL) with a Mikrotik RB4011 switch and a phone connected via an Eero access point.
- Key concepts and configurations were explained for the Mikrotik RB4011, Eero router, and WOL phone application.
