I added a LAN cable from the Upcountry Fiber wireless/4 port router to my desktop computer to get 950Mbps because the Intel Wi-Fi 6 AX200 160MHz wireless adapter was getting under 500 Mbps at 30 feet and two walls from the router. Pam's computer gets under 100 Mbps.
My iPhone 11 Pro allowed me to do a check at my computer and six feet from the router: 358/164Mbps down/up by my computer and 564/557Mbps down/up near the router.
Practically speaking, I could do with 500Mbps service and save $15 a month, but it sure is fun to download a CD load of data in a few seconds.
I don't believe anyone can tell a difference just surfing the internet between 50Mbps and 950Mbps.
