WiFi Analyzer

Wi-Fi signal analyzer, channel planner and local connection diagnostics tool.

Built with GTK4/Adwaita. Part of the Danne L10n Suite.

Features

• Scan access points through NetworkManager D-Bus; no privileged shell command is required.
• Filter results by network name, BSSID, channel or security type.
• Inspect 2.4, 5 and 6 GHz bands with a channel-overlap graph.
• Navigate the channel graph with Left/Right and Home/End, filter channels with Enter/Space, and hear channel selections read by screen readers.
• Show NetworkManager's announced AP bandwidth when available, with a clearly marked estimate as a fallback.
• Mark 5 GHz DFS channels. Their availability depends on the local regulatory domain.
• Recommend less congested channels from observed signal overlap.
• Sort results by signal, channel, or security and group repeated SSIDs by access-point count.
• Export visible, filtered results as CSV, JSON, anonymized JSON or an HTML diagnostic report, with a user-selected file name and destination.
• Keep up to 100 local scan summaries for future history views. Scan data never leaves the device and can be cleared from the menu.
• Mark the active access point and use the actual channel width reported by iw for that radio when available.
• Identify Wi-Fi 4, 5, 6/6E and 7 for the active link from iw PHY markers. A generation is never guessed for an unconnected AP.
• Compare consecutive scans to identify new, missing, or materially changed access points.
• Create a self-contained HTML diagnostic report or an anonymized JSON export for safe sharing.
• Select an access point to identify the strongest overlapping neighbours.
• Show the active connection's gateway and DNS servers from local system diagnostics.
• Use optional 60-second monitoring and location profiles for private local scan history.

Installation

PyPI (Debian/Ubuntu)

GTK, libadwaita, PyGObject and Pycairo use native system libraries, so install them from your distribution before installing the Python package:

sudo apt install python3-gi python3-cairo gir1.2-gtk-4.0 gir1.2-adw-1 network-manager iw pipx
pipx install --system-site-packages wifi-analyzer

Debian/Ubuntu

wifi-analyzer is distributed through the Danne L10n Suite APT repository, not the default Debian or Ubuntu repositories. Add the repository before installing:

wget -qO /tmp/yeager-repo-key.asc https://yeager.github.io/debian-repo/yeager-repo-key.asc
sudo install -m 0644 /tmp/yeager-repo-key.asc /usr/share/keyrings/yeager-repo.asc
echo 'deb [signed-by=/usr/share/keyrings/yeager-repo.asc] https://yeager.github.io/debian-repo ./' | sudo tee /etc/apt/sources.list.d/yeager.list
sudo apt update
sudo apt install wifi-analyzer

If APT still cannot find the package, check that the repository appears in apt update and run apt-cache policy wifi-analyzer. The signed APT index may lag behind the latest release. To install the current version, download the .deb from GitHub Releases and install the downloaded file with sudo apt install ./wifi-analyzer_*.deb.

Source packages follow Debian policy and can be built with:

dpkg-buildpackage -us -uc -b

Fedora/RPM distributions

The release includes an RPM built on Fedora 44. Download it from GitHub Releases and install it on Fedora 44 with sudo dnf install ./wifi-analyzer-*.rpm.

Build the source RPM with:

rpmbuild -ba packaging/rpm/wifi-analyzer.spec

GitHub Actions builds both .deb and .rpm artifacts for releases and pull requests.

Translations

The user interface uses gettext catalogues for 20 languages. Swedish is translated and reviewed; the remaining catalogues are ready for translation. See po/README.md to contribute or validate a translation. The Swedish manual page is installed as wifi-analyzer(1) and is maintained in docs/man/sv.

Flatpak

Flatpak-paketet byggs från build-aux/io.github.yeager.WifiAnalyzer.json. Det kan installeras med Flatpak Builder tills paketet har publicerats på Flathub.

flatpak-builder --user --install --force-clean build-dir \
  build-aux/io.github.yeager.WifiAnalyzer.json
