I have the same router and I was enabling Band limiter on the guest network. This is kinda bugged and limit every network, disabling QoS bringed back the original speed. Also be sure to be on latest firmware or you may encounter reboot loop on some providers.
Hope it helped.
Good day to everyone,
I recently purchased this router and noticed that in the LAN section I can not tag any attached port. Any way around this maybe by nvram? My philips hue must be tagged on the same VLAN of IOT or it will not work :(
I am in the return window and the BE19000 is on same price...
