Man I really feel your pain also. I had the same issues with the MK63 tripple modules Mesh system with a 1Gbps backhaul link to all three of them. My wired computers all work while the mesh nodes keep turning all kinds of colours and I could never keep them blue. It was draining my life in the house.
The speed was really good when they work but the stability and the simple fact that they don't use all three radios when backhaul is gigabit ethernet caused me to switch to a different system which is now installed since 5 months ago and forgotten about.
I have sold my MK63 mesh at a much lower price just to get rid of them. Found that Netgear support is unable to understand simple networking issues even when I gave them proper information (I worked in telecom myself for more than 15 years) and are just there as a psychological cusion for the furious people.
I currently hold only the mobile Netgear Router M2 and for the price it's fine but it took some time to get it to work properly also. I don't understand how a respectable company like netgear can miss the point so hard when it comes to UX and how networking should be a deploy-and-fforget solution and not a constant pain.
It's also not inline with the prices that netgear practices (which are higher than competition) in complete disregard with the poor stability and sea of complaints they get, while similar competitors at lower prices serve sound equipments, very stable and simple user experiences.
The MK63 took me hours to setup even when I work in telecom and I know exactly what I'm doing and how I want them to be setup (which is bridge mode). Still when setup as bridge (not as routers), and offload the routing workload to a proper router, the MK63 still could not hold stable connection more than 2 weeks.
I loved netgear and their innovation but it comes at prices that I for one am not wiling to pay. Time consuming, cost inefficient and unstable. Not to mention insufiicient for IoT (each MK63 node cannot hold more than 20 connected devices I counted).
