Internet problems with vodafone?

And that's about Vodafone with me.

I have a dsl line of 50,000, live near downtown in Dusseldorf and did not have that problem at the time.

When I download something. I do not get more than 3-6mb per second, though I have a 50k line.

I have already phoned several times with vodafone and have also measured the lines and it come to me to the router 102,000 actually, but no matter what I download with the pc or laptop, any page, it loads with only 3-6mb.

I have restarted the router several times, made tests and my line is very unstable.

Especially lately was a buddy with me, who has an app on the phone, with which he can measure exactly how much he gets on my wlan on his phone and he had 25k on it, while I clearly get with a Wi-Fi cable a fivefold of it,

Maybe an expert is available who could help me. Because Vodafone can't help me there…

my router is configured correctly and everything is there properly, what should be.

However, I noticed recently that I had a "muffling" something that was displayed in dB and the value was almost equal to the number given above the box above it (about 13.6 dB was given and 12.9 dB seems to be blocked,

Is it possibly because of it? And Vodafone can't see it?

I have a speed port 701v and am really helpless now, because 40 euro a month are no longer worthwhile, since I have been only 3-6 months.

"[…] while clearly getting fivefold with a Wi-Fi cable."

For the first time, there are no Wi-Fi cables. Wlan means "without cable network".

Wlan cable would therefore be "without cable network cable"?

Then could you tell me how your PC is connected to the router? By LAN cable or via WLAN?

Yes, I've lost myself, the fatigue comes out.

lan cable of course, although it is even a minimal difference with me, whether I have a nem lan cable or wireless connection

Really strange, actually it would have to run without problems, but if I go now, for example, on chip.de or steam something would download something, I would have a fluctuating number of every second changes of 2.5-6 mb.
