Wi-Fi Speed (Help me understand the varying speeds)

I have 3 Routers (Apple Airport Extreme Base Stations) all hardwired to each other.


My 100 Mbps Fiber Optic service comes from a box on the outside of my house into the attic & then down to the 1st Router into a room on that side of the house.

The Fiber Optic service comes directly to my house & is not shared with other subscribers nearby.


The 2nd Router (in a separate building in my back yard) is hardwired (underground) from the 1st Router.

Attached to the 2nd Router (all hardwired) are my Desktop Computer & 2 printers.


The 3rd Router (in my Living Room) is hardwired (through the attic) from the 1st Router.

That Router is 1 Generation newer than the 1st & 2nd Routers.

Attached to the 3rd Router is my TV (hardwired), my Security System (hardwired) and my Laptop, 2 iPhones, & 1 iPad (on Wi-Fi).


When I do a Wi-Fi Speed Test on my iPhone 14 Pro Max in my Living Room near the 3rd Router, I get a Download Speed of 94 Mbps & an Upload Speed of 93 Mbps.


When I do a Wi-Fi Speed Test on my Laptop in my Living Room near the 3rd Router, it shows a speed of 433.3 Mbps (on only a 100 Mbps service).


When I do a Wi-Fi Speed Test on my iPhone 14 Pro Max near the 1st Router, I get a Download Speed of only 37 Mbps & an Upload Speed of 83 Mbps.


When I do a Wi-Fi Speed Test on my iPhone 14 Pro Max near the 2nd Router, I get a Download Speed of only 36 Mbps & an Upload Speed of 80 Mbps.


When I do a Wi-Fi Speed Test on my Desktop hardwired to the 2nd Router, it shows a speed of 1.2 Gbps.


Question is: Why such drastic speed variations?

Normal and expected.

You know that your Internet connection is about 100 Mbps. Your result here shows the connection speed between the laptop and the 3rd Router, not the connection speed between the laptop and the Internet.

And if you restart the iPhone and the 1st Router and temporarily locate the iPhone about 10 feet from the router with clear line of sight between the iPhone and router, what reading do you get on a few tries?


When I do a Wi-Fi Speed Test on my Desktop hardwired to the 2nd Router, it shows a speed of 1.2 Gbps.


Same thing as above. This is the connection speed between the Desktop and 2nd Router, not the speed between the Desktop and the Internet.

THANKS for the information!


Of course you are right.


When I separately restarted the 1st & 2nd Routers & my iPhone, the speeds on my iPhone were in line with my 100 Mbps service.


However, I still am having problems understanding why my laptop can show a speed of 433.3 Mbps & my Desktop 1.2 Gbps with only my 100 Mbps service.

Both of those tests were done using the "Change Adapter Settings" on each device.


But when I do the test on my Laptop using "Speedtest" it reflects the 100 Mbps service I have.
