Difference of internet speed on LAN and Wi-Fi

Hello guys. I just bought a router (ipTIME N604R plus).

Here are the specs:



I'm just curious why there's a big difference between my speed on LAN and on Wi-Fi. I know there's a disparity but I just think it is too big? Or this one is still normal?

Speedtest on my laptop connected through LAN:



Speedtest on my iPhone 5S connected through Wi-Fi:



If someone can explain the reason to me, I would really appreciate it. I just want to know why. Thanks!

Simple, Ethernet throughput is 1Gbps, Wi-Fi maxes out at 300Mbps, thus ethernet gives more headroom for uncompressed data.
Also you performed the 2nd test through mobile phone, speedtest.net is flash-based test, so it requires lots of CPU as well, and that's where your phone might have distort the results.

Yup I know that difference but the speedtest on my iPhone through Wi-Fi doesn't even reach that 300 mbps. Someone told me it's an iPhone limitation already.

it's not going to reach 300 Mb/s anyway, since your internet is not that fast, you can see that it tops out at around 95 Mb/s on your Ethernet-connected computer.

Regardless, the speed of the switch (or WAP in your case) has nothing to do with internet, but how fast data travels from your device to the switch. In a perfect lab environment, the actual speed of the connection between your iPhone and the WAP could get close to 300 Mb/s.
