I have had my Tab E 9.6 for a couple of years now and yes its a Tab E not A like the title. I just upgraded my wifi router and my providers speed is supposed to be 600mbps. 'When I run the speed test on my other devices I get anywhere between 200 to over 600 depending on the device but when I run the test on the Tab I only get close to 40mbps. My router does not show separate 2.4 and 5 ghz speeds. Is there anything I can do to get the Tab to run at these speeds or am I limited to the wifi hardware in the Tab itself?
