There are not enough pins in the Internet connector on the router. Is it critical?

Question

Computer networks

I bought a ZyXEL Keenetic 4G III router yesterday. I tried to set it up and connect, but it did not work. Even through a direct LAN connection between the router and the PC, the interface did not open. I don't know what's wrong. But now is not about that.
I was more puzzled by the lack of half of the pins in the Internet connector of the router. Although they are all present in the old D-link. Below I will try to describe their arrangement in binary code:
0 0 1 0 0 1 1 1
Where 0-there is no pin, 1-is present.
Please explain how the missing number of pins will affect the Internet connection, which ports and outputs will be unavailable, and in general how "dangerous" is it?

Answer 1

Look at the pictures: ydoma.info/kompjuter-cvetovaja-shema-obzhima-raspi...
In most cases, four wires are used, and the rest work as a screen. At high speeds or with a long wire length, this plays an important role, but at short distances, not so much.

Can I use a proxy, VPN, connect to TOR, I2P and other protocols with so many pins?

does not depend at all.

Do you know if this router has a USB connector, is it only for a 3G modem, or can you connect flash drives there and use the router as a torrent download?

see the instructions for your router. Or maybe there are alternative firmware for it, but it's better if you read their description yourself.

Answer 2

These pins are exactly what you need to work at a speed of 100 megabits.

Answer 3

It looks like you mixed up the beginning and end.
And so - a pair of pins 1,2 and 3, 6 - this is enough for a 100 Mbit connection for a standard crimp.
