Troubleshooting ASUS AI Mesh Router Problems [Support] 
**Describe your problem**

Hi, I have recently upgraded my networking setup from ASUS AC (1x AC5300 + 2x AC86u) line of routers to ASUS AX routers (1x AX11000 + 3x AX6100). They work flawlessly together, and it goes to show how far they've come since releasing their AC routers. In fact, I think ASUS is the best company in term of AX routers, as Unifi seem to be a bit slow updating their line of products, 

ASUS is well-loved for its networking products. However as great as they are, and as happy as I am to be one of their customers for the past 10years, one problem has continued to plague it. I am of course referring to the inability of this plugin to fully function with this network configuration. I want to try and understand as specifically as possible what is causing this problem in the hopes that ASUS will address the problem, or at least provide us with a solution.

So here goes;

**Describe what you have tried so far**

So firstly it is important to note that all my nodes use ethernet backhaul, and are connected via AiMesh 2.0

I am able to make use of this plugin as long as the devices I want to use are connected to the main router, however, the second devices move to a mesh node I am unable to control them using this plugin. They obviously still respond via WebUi

I have a test shelly setup, and I want to try and understand what is causing this.

Firstly I downloaded an iPhone app called 'Discovery- dns-sd browser' which is meant to discover bonjour/mdns devices. This app is able to discover the Shelly devices on all the nodes I am connected to on the network under '_http._tcp.' protocol'. 

Secondly, I installed 'npm install -g shellies', and discovered that the test shelly connected to the mesh node is indeed discoverable, and restarting the homebridge-shelly plugin adds the test shelly into Homekit. What I've observed under the homebridge-shelly GUI is that despite it appearing as Online, the refresh timer does not update when connected to a mesh node. **Ok, so does that mean multicast mdns is not a problem?**

I then proceeded the run 'netcat' as instructed by the wiki. The two devices connected to the main router would periodically send commands, however, in over 30minutes, the test shelly connected to a mesh node did not. I also tried several LAN/Wifi configurations but this did not change the problem.

So my question is, is that a CoAP issue? Is there any way to fix it using a routing table? and can I provide ASUS with any data that could help them get to the issue and fix it once and for all?

**Environment:**
 - Shelly device(s): Shelly 2.5s, Shelly 1PMs, Shelly Dim2, Shelly RGBW2
 - Plugin version: 0.18.0
 - Device running homebridge: Raspberry Pi (Managed switch (w/ all IoT hubs connected to router)
