Corey bought an ORBI MESH router and enjoyed 350MBps downloads, until recently. It's now down to about 10MBps. He tried another Linksys mesh router and the same issue happened. Leo says that it sounds like the problem isn't at the router level. Leo suspects that Corey may get full speed from a wired router. If so, then there's a congestion or interference issue. It could be a "WiFi hostile" environment that is causing interference. Maybe a lot of devices are clogging up the wireless spectrum where he is. Check out the wifi testing app called Insider.
