I noticed that I was getting around 80Mbps on my phone and iPad when they were on 2.4Ghz but when I swapped to the 5Ghz I’m getting nearly 140. Checking the speed on my fire TV which is wired, it’s 83. Disconnect from the wired and pick up WiFi, it’s 138. Why doesn’t it run at that speed when wired - there’s no choice between 2.4 and 5 on the wired side of things. Is there?
