Laptop Internet fast with Lan cable?

I once heard that if you connect the laptop with a LAN cable and with the router and download an automatically opened softair, the internet should be fast. Is that correct?

Thank you in advance in advance and have a nice Christmas.

Do not be angry, but can you revise your text? I will not be smart about that.

Happy Holiday.

The internet is fast. Whether your access latanzarm and broadband depends on the individual case. A bad Internet access you can barely compensate locally.
But a LAN connection should always be the first choice. Wi-Fi is very flexible, but also has its friction losses.
