Does length of coaxial cable affect Internet signal?

So, the long answer made short is that no, coaxial cable does not slow down your Internet.

How does data travel through coaxial cable?

Coaxial cable works by carrying data in the centre conductor, while the surrounding layers of shielding stop any signal loss (also called attenuation loss) and help reduce EMI. The first layer, called the dielectric, provides distance between the core conductor and the outer layers, as well as some insulation.

How fast are the data speeds with coaxial cables?

between 50 and 500 Mbps
And with coax we now reach speeds between 50 and 500 Mbps (6.25 to 62.5 MB). So internet by coax has since become as fast as by optical fibre. But new technology enables us to actually boost the performance of coaxial cable. Due to DOCSIS 3.1 the old TV cable can equal the speed of optical fibre.

Can I use any coaxial cable for internet?

All your coax will tie into it. With a multi-port setup they probably have a serial splitter. They should have labels saying things like -3.5dB . Your room might be connected to one that says something like -7dB .

Does signal degrade over coaxial cable?

Simple answer is yes, a long length of coax can absolutely cause signal loss.

Is coaxial slower than Ethernet?

What we found was not surprising. Whether connected by Ethernet, Wi-Fi or coax, the results were about the same. They surpassed the rated speed of 50 down, 25 up. We weren’t able to duplicate the claim that internet speeds were slower over coax than they were over Ethernet.

Is coax cable needed for WiFi?

Q: Do you need a coax cable for internet? If you have cable internet, then yes, you do need a coax (or coaxial) cable to connect to the internet. Your internet provider should give you one with your modem, but if you’re missing one, you can find them for pretty cheap on Amazon.
