network speed issue Switch speed problems

[Olithelombax]

Between my PC and modem i have a TP Link TL-SG1008D hardware version 5.1. Most of the time I only get about 9Mbit/s on my connection to it. I read that it has "Auto-negotiation ports provide smart integration between 10Mbps, 100Mbps and 1000Mbps hardware." thinking that this is the root of my problem. Seeing how it's not a managed switch I dont know how to fix this. Does anyone have any tips or tricks, or will i just have to bye a new switch that doesn't decide how much speed I get?

How are you measuring the speed?

 

Are you doing an internet speed test or something on google?

[RageTester]

Have you tried a different cable? Are you sure modem supports gigabit speeds?

[mr fobs]

Just confirming. What speeds are you expecting and have you tested your speeds on other devices?

I have tested the speed using speedtest.net. I also get the same resuts when downloading games from steam, movies etc.

I have tried with different cables but it does not change anything.

I get 9.4Mbps up and down. When it works i get 500 down 20 up, witch is what i pay for

I get the same problem on my laptop and desktop.

And do you never have the issue if you remove the switch? Did you try changing the cable between modem and switch as well?

 

If so then the switch is probably just faulty.

Faulty switch or might be the problem from the ISP?

Might be try to check your LAN status, it should show 1.0 Gbps like below.

I read that it has "Auto-negotiation ports provide smart integration between 10Mbps, 100Mbps and 1000Mbps hardware."

Means it's auto-negotiating of local LAN speed between those speeds depending of what you connect to the switch. Older devices can only support Ethernet/Fast Ethernet, hence, auto-negotiating. And such thing are on every single switch nowadays.

The speed directly form the modem is as it should be. So, new switch then. Should i look for someting witout the "speed controll" or anything else I should be aware of?

The "speed control" doesn't exist and is just a term for the auto-negotiation that is the de-facto standard nowadays. You can't get any switches without it. They all have it.

Did you try to normally transfer files over the network? Say, to a NAS or from one Windows machine to another? I'd check the speeds and consistency with that before going out, buying a new switch and figuring out it's something that the router does or that it's actually an over-booked cable connection.

Can it be the router if the wifi speeds are good and consistent?

Sure, because you never know how a router handles switches and more than one Ethernet device.

How many Ethernet ports does the router have? Because some might have trouble with the QoS when they are designed to have only one Ethernet-capable device connected.

The router has 4 ports. One is used for the TV-box and one goes to the switch, witch has 8 ports.

I found out that there was another switch between the "problematic switch" and the PC. After removing it the speed jumped to 94Mbit/s. Then I replaced the remaining switch and got the propper speed on one PC but another went back to 9Mbit/s.

 

There are way to many possible points of failure on my network for me to find a propper solution, so  for now I'll just run some temporary wires to get things working better.
