Switch only 100mbit?

I have cable internet with 200mbits at Vodafone. They come when I connect the laptop directly to the router via LAN cable. However, the router is on the ground floor and the pc is used on the first floor. I have now bought a switch that is connected to the patch panel in the basement and to the router by cable so that I can use the LAN socket on the first floor. However, according to the speed tests, only 80-90mbits arrive.
The switch I bought is this one:

TP-Link TL-SG108 V3 8-ports gigabit network switch (up to 2000MBit / s in full duplex mode, shielded RJ-45 ports, metal housing, optimized data traffic, IGMP snooping, unmanaged) blue metallic https://www.amazon.de/...01EXDG2MO/

The packaging says that it can do 10/100/1000 mbits. But does that mean that it can only do these three speeds and not 200?

The cables laid in the wall are cat5e and the cable that is used to connect to the pc is cat7.

The 10, 100, 1000 are different Lan standards.

Nen thousand can of course deliver less than 1,000.

If someone downloads something via your line at the same time as you (someone from your household), the 90 will be fine.

Okay, I'll do some tests later and tomorrow and see if that's that.

Exactly!

Try this out at different times. And discuss this with the other "network participants" if necessary.

I like to use this test page:

If you have several Windows computers on the network at the same time, you can also try out the CfosSpeed tool. (The demo runs for about 3 weeks, I think I can remember.)

This means that Internet access is prioritized on an application basis ("traffic shaping"). The ping times can also be optimized.

However, a separate (licensed) program version must be running on each computer. Network access is then optimized across all of these computers at the same time. Regardless of whether the computers are connected via LAN, WLan, or DLan. Or Wi-Fi repeaters or switches hang in between.

Further down on the page you will find a lot of clear explanations.

This tool has been around for many years. There's even an old MS-DOS version available.

And something else:

This switch can transmit "up to" 2 Gigabit / s within your home network. This has nothing to do with the bandwidth you booked with VF. This means the data transmission from computer 1 to computer 2.

Most network devices can only work with 1 Gigabit / s (=> ~ 128MB / s). More is not to be found quite as often. Possibly with the newest ("better") NAS systems.

I myself have an older NAS with 100 Mbit / s. Here the data rate is limited to approx. 12MB / s.

And my old router (FB 7270 + cable modem) could also only 100MBit / s. That's why I bought a 1GBit switch and operated the "internal" devices on it. And from there a LAN cable went to the router. At that time I still had a 32Mbit line to VF. Now I have a stable "250/50 Mbit" connection and 1GBbit would probably be technically possible.

What do you mean by "patch panel"?

For me, my cable router is attached to the https://dein-elektriker-info.de/multimediadose/ in the living room wall via a coaxial cable (with a union screw thread).

And this wall box is connected to the VF transfer point on the ground floor. Do you mean that with this "patch panel"?

Is there no TV cable in your house?

And if you "only" have the old sockets with two connections (for TV and radio), there are appropriate adapters for plugging in or unscrewing.

From the router it goes to my home network via an 8-port 1GBit switch.

VF transfer point => ("antenna" cable) => multimedia socket => (coaxial cable) => cable router => (Cat6 LAN cable) => switch => home network (PC, notebook, SmartTV, … )

If in doubt, you can also call Vodafone and have your line measured.

What arrives at the router is important. From there, the data streams are distributed in the home network.

And this cable router must of course also support 1 Gbit / s. At only 100Mbit / s this would be the "eye of the needle" that we're looking for.

A very plausible possibility occurs to me just now:

Some routers can also operate certain LAN connections in "green mode". And this is also the default setting for some LAN ports.

Then they work in the energy-saving 100MBit / s mode and not in the fast 1000MBit / s operation.

This can be set up accordingly in the router settings.

Unfortunately the speed is still the same. If I connect the laptop to the router and go to the Windows settings, "Show connection status", the transmission rate is 1Gbit / s. If the laptop is plugged into the LAN socket in the room, it is 100Mbit / s.

Which router do you have there?

Have you also tried out all available LAN ports on the router?

So also the port to which the switch is attached?

In my other answer, I had written something about this "green mode". Perhaps the switch is connected to such a throttled port.

I think I now know why. It looks like bad cables were laid in the house, which now have to be replaced. Still, thank you very much for your help.
