Yeah right. You can log in there and under Diagnosis you can see your speed “Measured values ​​for your Anschluss”. But you haven’t answered a very important question yet. How did you connect the TV box to the router? Directly or is there a WLAN box or powerline connected to it?

@LarsLöwe

The Internet box is your router. I assume that your TV box is connected to a WLAN Box2, as you wrote above? The best thing would always be to connect the TV box directly to the router. Then such disruptions will not happen. Do you have the opportunity to place your WLAN box slightly differently? As close as possible to the router or a place where the WLAN box could receive the router’s WiFi better? As long as the distance to the router is not too great, the WLAN boxes otherwise work pretty well. Restarting your WLAN box can’t hurt either. Switch it off briefly on the back and then on again.

The router and WiFi box are in the same room. It couldn’t be any closer.

If they are very close to each other, then the additional WLAN-Box is actually completely unnecessary anyway.

Simply plug the TV-Box’s LAN cable directly into the router and you will immediately get rid of all radio quality problems with the TV transmission 🙂

In order to be able to estimate the distances of the possible radio links, how many meters do you have between the router and WLAN-Box, between WLAN-Box and TV-Box and between the router and TV-Box?

And as a second question:

- an IB2 or IB3 as a router?

- as WLAN-Box a WLAN-Box 1, 2, or 3?

You can certainly ask yourself why the TV box is connected to the router via a WLAN box (Internetbox3 according to the picture above), even though everything is in the same room? But even then, in this case, the WLAN box would have to have an excellent connection to the router, so that your speed shouldn’t actually experience any stuttering. I would restart the entire setup, i.e. the WLAN box and router. Maybe then it will work perfectly again. If not, to isolate the problem, you would have to test connect the TV box directly to the router.

If your line is too weak, the installation in the apartment/house is poor or the TV box is not connected to the router via a cable, there may be problems or freezes when switching, but these may then disappear again. However, if the image is persistently disturbing, the connection to the box needs to be improved.

So I have the finest fiber optics and the TV-Box has a cable connection. However, there are small picture disturbances every now and then when switching. They practically only occur when switching. We’ve had that before when switching between different coded channels and they got it under control. I bet it’s the system 🙂

@LarsLöwe

I also had such a problem on the UHD channels when I had an unmanaged switch installed. Now I have replaced each with a managed switch. With one TV box everything has been fixed, with the other the image disturbances only appear briefly when switching on (only on the UHD channels).

@Cabonesha

The problems even occur if you connect the TV box directly to the IB.
And as long as it only happens when switching, the only option is to accept or switch to high quality instead of the best.

@Stephan_76

I wasn’t aware of that.

Then I’m one of the lucky ones 🎯without image disturbances, in my case thanks to the managed switch.

I don’t want to do without UHD…
