On the Wireless Protection > Mesh Networks page you can define mesh networks, and associate access points that should broadcast them. In general, in a mesh network multiple access points communicate with each other and broadcast a common wireless network. On the one hand, access points connected via a mesh network can broadcast the same wireless network to clients, thus working as a single access point, while covering a wider area. On the other hand, a mesh network can be used to bridge Ethernet networks without laying cables.
Access points associated with a mesh network can play one of two roles: root access point or mesh access point. Both broadcast the mesh network, thus the amount of other wireless networks they can broadcast is reduced by one.
A mesh network can be used for two main use cases: you can implement a wireless bridge or a wireless repeater:
Mesh Network Use Case Wireless Bridge
Mesh Network Use Case Wireless Repeater
To define a new mesh network, do the following:
On the Mesh Networks page, click Add Mesh Network.
The Add Mesh Network dialog box opens.
Make the following settings:
Mesh-ID: Enter a unique ID for the mesh network.
Frequency band: Access points assigned to this network will transmit the mesh network on the selected frequency band. Generally, it is a good idea to use a different frequency band for the mesh network than for the broadcasted wireless networks.
Note – Except for AP 50, all mesh network-capable APs transmit the mesh network on 2.4 GHz only. If an AP 50 transmits on 5 GHz, it is not compatible to other APs which transmit on 2.4 GHz.
Comment (optional): Add a description or other information.
Access points: Click the Plus icon to select access points that should broadcast the mesh network. A dialog window Add Mesh Role opens:
Role: Define the access point's role for the selected mesh network. A root access point is directly connected to Sophos UTM. A mesh access point, after having received its initial configuration, once unplugged from Sophos UTM will connect to a root access point via the mesh network. Note that an access point can be mesh access point only for one single mesh network.
Note – It is crucial for the initial configuration to plug the mesh access point like every other access point into one of the Ethernet segments selected in the Allowed interfaces box on the Global Settings tab.
Use the Delete icon in the Access Points list to delete an access point from the list.
Important Note – If you delete a mesh access point from the Access Points list, you have to plug the access point into your Ethernet again to get its initial configuration. To change the mesh network without having to plug the access point into your Ethernet again, do not delete the access point but instead click the access point's Edit button on the Access Points > Overview tab, click the Edit icon in the Mesh Networks section, and select the desired mesh network.
The access point icon designates an access point's role. You can search the access point list by using the filter field in the list header.
Your settings will be saved. The mesh network appears on the Mesh Networks list.
