Internet Issue (Terminal) 3 Mac Computers Wired Netgear Router


I have a home network with a wired Netgear Router and three Mac computers. The computers are as follows an iMac and two Macbook Pros. One of the laptops has a program called terminal running and my internet connection on my iMac and Macbook Pro are very slow. Currently I have the router locked with a user name and a password as well as super gluing the rest button.

After doing some research online I discovered that terminal is basically the architecture for the OS operating system. I have very little knowledge as to how one is supposed to issue commands. Is it possible to either limit someones bandwidth and or prioritize yours using terminal. If so what do I need to do to stop it? I have already reformatted my laptop and I would like to put an end to it.

I should mention that this is my network and they do not have permission by me or anyone else to modify settings. If I need to purchase a new router/router and switch or something else I will. I would also like to find out what steps I would need to take to prevent further modifications if they are able to remotely change settings.

Thank you in advance.

After some research online I found that there is something called ssh tunneling. I do not know if this is what is running or if there is a possibility terminal has the ability to limit bandwidth.

I was hoping that I would be able to gain some more insight into this but I still do not see any responses.

I do not have access to the laptop and do not know what commands are running.

Yes the SSH tunnel could be sucking all your bandwidth therefore making all the computers dog slow.

I don't know if this is the case, but if it is how can I prevent it from affecting other computers on the network? Also you still did not answer my question as to whether or not the laptop had the ability to limit my bandwidth on another computer.

If they cannot limit the bandwidth and it is just ssh tunneling can I use a new router with either QoS or a bandwidth limiting function? If ssh is similar to port forwarding can I use a router/switch to control all incoming packets?

I would be very grateful if I could receive a more thorough answer if you knowledgable on this subject.

What you have finite bandwidth, what ever you are conneting to via SSH tunnel is pulling most of it. The question you should be asking yourself is what value the tunnel has. Does it need to run 24/7 or could you start it at night? Does the tunnel need to be on at all what value is it bringing? Do a value estimate on the tunnel and then decide on whether you purchase more bandwidth or maybe put the tunnel on a different network.

I don't think you understand why I am asking for help. I am not the one using ssh or any other form of commands through terminal. It is someone else on the network and I want to find out how to stop it. I am not the one using terminal for anything.

When you say purchase more bandwidth are you telling me that I can over ride what they are doing with a new router that can limit bandwidth? Or a switch?

My plan is currently 1mb for upload and 15 for download.

First of all what do mean by "slow connection"

You type
"my internet connection on my iMac and Macbook Pro are very slow."
Is this when browsing pages or internet in general?
What is the configuration of these computers are they equal to the on not running slow?

How do you know an ssh tunnel is active and on two computers also?

Check the basics first.

One test you can perform is ping you gateway with larger packets like 1500 and check for errors o packet drops, this will show if there is a transmission problem.
Perform the test from all computers in the network and check if they are equal.
