The wifi of a Freebox relies on a technical chain where each link can cause a disconnection: Server firmware, radio configuration, hardware interference, software bug on a frequency band. Identifying the right link avoids wasting time on unnecessary manipulations. When the wifi of your Freebox stops working, the cause is rarely unique, and the solution depends on the box model as much as the network environment.
Firmware bug and Freebox Server update: the first reflex to have
Free regularly publishes updates for the Freebox Server, sometimes several per month. Some directly fix wifi stability issues. The update 4.9.19, for example, fixed a bug introduced by a previous version that affected wireless connectivity on the Ultra, Pop, and Delta models.

The problem: these updates do not always apply automatically. A simple restart of the Server is often enough to force the installation of a pending fix. Before changing any wifi settings, unplug the Server box (not the Player), wait about thirty seconds, then plug it back in.
If you are trying to understand why the wifi of my Freebox is not working after a recent update, the firmware is the first avenue to explore. A known software bug that has already been fixed by Free can explain a failure that seems inexplicable from the user’s side.

To check the installed version, log in to the Freebox OS interface (mafreebox.freebox.fr) and consult the “System Information” section. Compare with the release notes published by Free to see if your Server is up to date.
Wi-Fi 7 and MLO bug on Freebox Pop and Ultra
The recent models (Pop V8, Ultra) feature Wi-Fi 7 with MLO technology (Multi-Link Operation), which allows a device to use multiple frequency bands simultaneously. On paper, this feature improves throughput and stability. In practice, it generates a documented bug on specialized forums.
The typical scenario: a smartphone connected via Wi-Fi 7 loses the 5 GHz band. The user restarts the wifi on the phone. The Freebox restarts itself, cutting the connection for all devices in the household.
Workaround for the MLO bug
While waiting for a fix from Free, two options reduce the risk of crashing:
- Disable advanced wifi features (MLO, multi-band aggregation, Smart Connect) in the Freebox settings via Freebox OS, section “Wi-Fi”
- Force the devices that trigger the problem to use the 2.4 GHz band only, by creating a dedicated SSID for this frequency
- Check if the smartphone’s firmware properly supports Wi-Fi 7 (some manufacturers release fixes on their end)
This type of malfunction does not stem from poor placement of the box or a password issue. It is a protocol conflict between the box and the wifi client, invisible without technical diagnosis.
Invisible wifi network: check the radio status of the Freebox
When the wifi network no longer appears at all in the list of available networks on your devices, the problem lies upstream of any password or configuration question. The wifi radio of the Freebox may be disabled.
Several situations can cause this deactivation:
- An accidental press on the physical wifi button present on some models (Freebox Révolution, Mini 4K)
- An update that reset the wifi activation setting in Freebox OS
- A change of channel or band that put the radio module in error
The verification is done in Freebox OS, section “Wi-Fi”: the status should indicate “Active” for each band (2.4 GHz and 5 GHz). If the wifi is disabled, reactivating it from this interface restores the network in a few seconds.
Wifi channel and neighborhood interference
If the network appears but the connection remains unstable or very slow, the channel used by the Freebox may be saturated. In an apartment, several neighboring boxes often share the same default channels.
In Freebox OS, the “Advanced Wi-Fi” section allows you to manually change the broadcast channel. On the 2.4 GHz band, channels 1, 6, and 11 are the only ones that do not overlap. On the 5 GHz band, the choice is broader and interferences are generally less.
Freebox stuck at step 3: a false wifi problem
A common case of confusion: the wifi seems to stop working, but the Freebox itself has not finished its synchronization. Step 3 (“fiber signal detected”) means that the box has not yet obtained its internet connection. Without an active internet connection, the wifi may remain functional locally (devices connect to the network) but no page loads.
If your Freebox remains stuck at this step after a restart, the problem does not concern the wifi but the fiber or ADSL link upstream. A local network incident at Free, a poorly clicked fiber cable, or an issue with the wall socket are the most common causes.
Check the status of the Free network in your area via the subscriber area or community sites that list outages in real-time. If the incident is confirmed on the operator’s side, no manipulation on the wifi will change anything.
The distinction between wifi failure and internet failure remains the most useful diagnosis to make before any intervention. A device connected to the wifi with an “no internet access” icon points to the Free link, not to the radio module of the box. Testing with an Ethernet cable plugged directly into the Server resolves the question in seconds: if the wired connection doesn’t work either, the wifi is not to blame.
