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.

It truly puzzles me why no clear measurement is conducted here instead of endless speculation. And no, a speed test using an old Android smartphone on some random website is not a reliable measurement.

This is precise enough to provide a reference point to determine if there really is a bottleneck.

If the values remain relatively consistent at different times, it is sufficient to estimate whether the issue lies with the access or if there are problems within the internal network.

Iperf can still be used later but requires a certain level of basic knowledge that not everyone has.

If you have a second laptop on hand and know how to set up a file share, copying a single large file from one laptop to the other over your local network is a better indicator than any speed test to servers on the internet.

For a test from the internet, downloading from the gaming platform Steam is a fairly good indicator. Their servers are usually reliable and consistently fast.

As has been mentioned many times before, the internet connection is one thing, but the home network is another.

However, if the result shows that everything is fine, it is a simple and quick method. For that reason, T_im_Norden is absolutely right.
