I believe Ookla Speed Test, and other 'so called' Speed Tests, are a misdirection effort by the ISP's.
Many questions & remarks about
'Internet Speed' do not mention the
facts of ISP's actual 'delivery of signal'.
We customers do not pay for 'speed'; we pay for 'Bandwidth' also
known as 'Throughput'. We pay for
enough 'Bandwidth' to support our
desired Viewing, Browsing, email,
messaging, and 'Large File Sharing'
needs.
FibreOptic 'Speed' is 'One Speed' on the Trunk Cable from the ISP Front
End Origin of Service to our local town Hub. That Hub delivers 'paid for' Bandwidth to our local Neighborhood 'FTTN', AerialTerminal or Curb Pedestal 'FTTC', and in new
neighborhoods 'FTTH' ending,
typically, at a in-Home Fibre Optic
Terminal or on a Outdoor Wall.
It's up to each customer to decide
their level of Bandwidth.
That job can be difficult depending on how the Customer manages the 'Router, HDMI & Ethernet Cables, & Settings for all that equipment.
That's why 'ISP Routers' are the best choice for any ISP Customer.
That Trunk Cable serves millions of Customers including Business Customers who may require Giga,
Nano or Terra bit Bandwidth.
Residential Customers MAY require
such higher Bandwidth when using online Gaming, 2160p UHD TV, or multiple TV's, Game Module's,
Cellphone Data and/or Frequent and
Long Cellphone conversations all at the same time.
Tweaking Router, Ethernet Cables &
WiFi, Streaming Devices such as
Apple TV 4K, and Bluetooth needs,
is straightforward, only, when the
Customer follows ALL Setup AND
Settings directions. Yeah I know; it
ain't Grandpa's TV anymore.
My advice is to make Internet Use
as Simple as We Can, experimenting
can be a real drag.
THE BEST Setup for Residential Customers happens when WE HAVE ALL OUR NEEDS COVERED BY A VISITING TECH WHO CONFIRMS
HOW WE INTEND TO USE THEIR
SERVICE CONNECTION.
