This is very important, yet many have no idea 😊
You have been in the same place for over 20 years, had your data cables installed back in the day, and you now wonder why everything is not super fast, even though you keep updating your equipment (switches routers etc) to the latest standards.
The answer is simples (meerkat speak), you have a bottleneck, and what a restriction, your data cable is not capable of moving the data around as quickly as you would expect.
Example a CAT 5 data cable will only move data around at 100Mbit ☹, CAT5e will do it 10 times faster, CAT 6 100 times faster and CAT 8 400 times faster 😊 . CAT 7 is not normally used.
Remember your data will only move around as quick as the slowest component on your system (in series) will allow, so if you have a slow data cable that will be in most cases your “bottleneck”.
Wi-Fi Vs Ethernet
It’s a bit of a no brainer, ethernet is more secure, more reliable and nearly always much faster than wi-fi.
The fastest Ethernet speeds today are 10Gbps or higher, while the fastest Wi-Fi speeds
theoretically max out at 6.9Gbps, though normally speeds are much lower than this, usually less than 1Gbps.
So I suggest, stick with your Ethernet, but if your data cable is very old consider an upgrade.
