DSL speed very slow in new build

Novice
1 of 6

Hi all. We recently moved to our newly-built house and are experiencing very slow DSL speeds; getting only 5-10 Mbps instead of the max 70Mbps available in my village. I thought it was initially a problem with the cabelling I'd done myself, but even when the Internet box is connected to the DSL line with the supplied cable (via a patch panel I'd punced-down myself), the speedtest on the box itself only reads < 10Mbps. If the cable hadn't been punched down properly, I'd be getting nothing at all, correct?

My network is as follows: patch panel, Swisscom Internet box and gigabit switch in the cellar where the line comes in, then via the patch panel to the living room where I have a Netgear router connected to my TV 2.0 box. TV is virtually impossible to watch; I can access the TV guide, but it says there is no channel being broadcast, yet I can watch in playback or recorded programmes, albeit very stuttered. However, I can watch Swisscom TV over the internet on another PC or via the app on my iPad. Is there anything I can do before calling out Swisscom or an electrician?

Hi

Did you try to connect the router directly to the incomming line and then test with a directly to the router connected laptop?
This way you can be sure that it is not your installation.
What does the swisscom line check say about the possible speed: https://www.swisscom.ch/de/privatkunden/popup/glasfaser-checker.html

Thanks for replying. I don't actually have a laptop with an ethernet connector, but I can bring my work machine home and try that. Both my desktop PC in the office and Mac-mini in the living room display speeds of anything between 5-15 Mbps.

 

Fibre-optic isn't available in my village and I've no idea when, if ever, it will be.

The checker also shows max. possible speeds for the location.
So if there is written 15Mbps, you can stop searching for any errors...

Ah yes, I see now. The max speed available in my village is 70 Mbps. My friend who built next door gets 65-70 Mbps.

Connected a laptop to the router and still only getting <10 Mbps. Think it's time to give Swisscom a call.
