Hi @Martin_Joyce ----- Thank you for the update, glad to hear things are stable with the Node 2 mounted directly to the router.
While I am not personally familiar with the Asus router you are implementing and cannot comment on the devices capabilities, the first thing that DOES jump out at me is that it is an 802.11n device. As mentioned by our CTO Brian, in regard to what a “healthy” Wifi configuration could resemble:
This technology moves over time–a first-generation 802.11n router will underperform compared to something more current, simply because the newer ones have more CPU/RAM. If at all possible, make sure your router does 802.11ac. Even if your endpoints are n-only, the bandwidth hungry phones/tablets/laptops are more likely to have ac support, which will get them out of the way a little bit.
