Ethernet network speed

[Jaroslav Matus]

Hello, I would like to ask you about connection speed. It is known fact that wireless internet speed is affected by number of users, but is ethernet speed affected too? For example, if you have 4-ports router, will there be any difference in speed, if you will use one or four ports at the same time?

And max router speed is only for wifi or it is for ethernet too? I read that yes but I have 50 Mbps router and sometimes the speed is more than 50. (I wrote sometimes becouse I have an odd internet, it is only 16 Mbps but sometimes I have some deviations and I have much faster connection.)

It can be affected depending on how many other connections are on the router. Is your ISP speed 50Mbps as well? Also it depends on the type of cable you are using as well.

You have a number of different speeds on your router. The most common people are concerned about is the internet speed. All the users compete for the same 50mbits or what every you buy from your isp.

The lan ports are basically a switch. Technically on a router with gigbit ports all 4 ports can send 1gbit and receive 1gbit all at the same time. This means the switch has a total bandwidth of 8gbits/sec. There is no realistic condition where this can be used but what it means is adding a user to the lan does not slow the others down.

Wireless is shared media. If you have a router that says it runs at 450m that means there is a total of 450m for all the devices to share. Even with just the router and 1 pc they interfere since only 1 device can transmit at a time. There is a lot of extra wasted bandwidth because the devices do not share well and the more device you add the more the overhead there is.

Thank you for your answer. I have 100 Mbps cat 5e UTP cable. No, my ISP speed on paper is 16 Mbps but sometimes it is more. It is other thing I do not understand but probably I have to ask my provider about it.

Thank you, it is exactly the thing I wanted to know. I am new here, now should I pick your contribution as a solution?
