Thank you for the explanation. Still troubleshooting this connection. I am using a note 9 to connect to my deco E4R in AP mode. My router is a Netgear R7000. WiFi off. From the router, I pull the cable directly to the main deco. I am on 100 mb download unifi. Only getting 50 mbs even though I am next to the deco. Any ideas? I also noticed that there are two classes of wireless download speed for all laptop/tablet/phone. One category is 50 mbs (note 9, s8), the other is 30 mbs.
I cannot change the WiFi settings since mesh wifi does everything automatically. Little overlap between signals since house distances are far. So no noise. Will wifi 6 router solve the problem? Or is my deco not that good? Based on ts explanation, I should get the 100 mbs since the router can handle it.
Home Networking Maximum WiFi Speeds, ... or why my wifi so slow?
