I have FIOS internet 25/10 Mbps speed that is consistent. Actiontec router worked well but purchased Quantum router to get the guest WIFI and hopefully better performance and tools to manage kids usage. What I found is that my VPN access for work is very slow and choppy with the Quantum router. Compliance training videos will not play at all but when I switch back to the Actiontec it is ok and I can see and hear the videos. Other bandwidth or connection issues are also visible with freezes. Consistently better with the Actiontec.
I have a coax connection from the ONT to the router and run the router to a switch for my computers.
Need to determine whether the Quantum router is faulty, whether it is just not able to handle the VPN and what I should do to get decent VPN performance and guest WIFI.
