Dear reader,

Router/Modem:
Technicolor TG789bvn

Internet provider: Tele2/T-Mobile
Download speed could be maximally 100 Mbps (I have a 100Mbps subscription)

I have some connection problems and I'm trying to find the reason;

I went to the configuration website of my modem by typing in the IPv4 address with username and password in a webbrowser.
There is a row with actual data speed [Mbps].

Question 1: What exactly does this 'actual' data speed mean? Is this the download speed I receive from my internet provider at the input port of my modem? See the images.

Also, this actual speed fluctuates extremely between 13Mbps - 140 Mbps.



This change from 13Mbps -> 117 Mbps happened in only 20 seconds or even less...

Question 2: Should this Actual Speed be constant? Or are huge fluctuations always happening to everyone?

Sincerely,
R3intje
 
Well, this is your wireless configuration page so it might be a real-time display of your wireless. If you want to see if you have fluctuations in your Internet speeds, connect to your router with a wire and test using fast.com and dslreports.com/speedtest and post your results here.

My T-Mobile subscription: 100Mbps

T-Mobile expects my maximum downloadspeed to be: 70Mbps

My maximum ethernet downloadspeed: 50 Mbps

My maximum wireless downloadspeed: 42 Mbps

But, at least a couple of hours per day, the downloadspeed drops to ~0.1 - 10.0 Mbps

The reason I was checking the configuration page is to find out whether these fluctuations could be caused by the wiring or by the modem/router itself.
