Peplink is offering on the newest Firmware build 8.1.1 is ability to support wireless mesh network. This feature offers a true mesh between the main router and the access points that are attached.
- You need one Peplink|Pepwave router that has 802.11ac or newer Wi-Fi integrated – or – you need one Peplink|Pepwave Access Point that supports mesh that is connected to the LAN via Ethernet. This is a wired mesh AP, it can allow other wireless mesh APs to join the network.
- You need a second Peplink|Pepwave Access point that is 802.11ac or newer – this will wirelessly mesh to the first AP/Router.
- You need a firmware that supports these features. That would be 8.1.1 8 (in beta now) for routers and 3.6.2/3.7.3/3.8.1 16 (in RC now) depending on your AP Wi-Fi Generation (3.6.X = 802.11ac 3.7.X=ac wave 2 3.8.X=802.11ax/Wi-Fi 6)
- Your mesh AP will still need power. This is “wireless” but it is not magic. Power from a wire is still needed wherever you put this “wireless” mesh AP.
