ᐅ Poor Wi-Fi in a Newly Built Home Despite Fiber Optic Connection

Hello. Today, after 6 months, we finally got internet in our new build. I set up the fiber optic connection on the FritzBox 7590 router. For that, I reset the router to factory settings and configured it according to the fiber installation guide. Then I updated it to the latest version. Somehow, the Wi-Fi isn’t as fast as expected. What could be the reason? The router is located in the utility room (ground floor corner) on a cabinet. Our living room is in the opposite corner on the ground floor. There, we have 3 out of 4 bars, sometimes even less. The speed is not particularly good either.

In the upstairs bathroom (directly above the utility room), the connection is practically non-existent. If I go to the upstairs hallway, I get 3 bars. Shouldn’t the signal actually be stronger throughout, even without a repeater?

The fiber modem and the FritzBox are connected by an Ethernet cable I already had. Should this cable be upgraded? Are there any other tips?

The switch for the LAN outlets isn’t connected yet. I still need to order it and install the wiring.

Did you perform a reset of the Fritzbox before setting up the new system in the house?

Your LAN is not disabled, as can be seen in the first screenshot you took where LAN 1 is active.

The reason your laptop is not using the LAN could be that it prefers to connect via Wi-Fi and therefore does not use the LAN.

You don’t need to change anything in the wiring.

Once the access point is up and running, you will have full download speed.

The corner of the installation still needs to be finished.

I assume the blue cables are the network cables? Are there really only 4 simplex cables for the entire house? Wow... I’ve never seen fewer; my record low was 7 simplex cables (or none at all in older houses).
But well, everything works over Wi-Fi anyway 😉

Joking aside, if there really are only 4 cables, terminate them on 2 duplex outlets (used as a patch panel substitute) in the utility room. Connect these to the router’s yellow ports. Then plug the AVM 2400 upstairs (upper floor) into a power outlet. Set it up as a Wi-Fi bridge, then use a patch cable from the AVM 2400 to the LAN outlet on the upper floor. Done.

Reading all this, I think there should definitely be a service for self-builders and electricians that offers Wi-Fi simulation on building plans. Simply go through the model home park and take reference measurements for attenuation. Then start Ekahau and you're good to go...

Completely crazy idea 🙂 There are supposedly companies that offer exactly this... but unfortunately, it doesn’t interest many people because 99.99999% of home builders approach it just like the thread starter here. It’ll probably work out fine with the Fritzbox router, and you don’t really need cables anyway, since there’s Wi-Fi. I could go on about this for days.

But as a special offer for electricians or interested self-builders... I've never really looked into it.

We do that too, but not for 160 sqm (1,722 sq ft), more like for 160,000....
