Deco m4 mesh with Zyxel router
Hi
inreceived a Zyxel 6501 router from our ISP and because of connectivity I bought a 3 pack deco m4 mesh system. This was advised by our broadband provider and is exactly what our neighbours have.
I seem to have set it up and created a new WiFi network. The main deco is plugged into the ISP's router and the other 2 are connected to the main deco via WiFi.
both WiFi networks are there but the speed is massively down. The ISP says the speed they see is 200ish mbps but I am seeing perhaps 2-5mbps when more more than 10 feet away from the main router.
could the two networks be interfering with each other? Do I just need to turn off WiFi on the ISP's router? Or do I need to make additional changes in settings?
