How connection type detection works
The Network Information API exposes interface type (Wi-Fi, cellular, ethernet) and performance estimates (downlink, RTT, effectiveType). All of it is read in the browser — no app install.
Note: effectiveType values like “4G” describe an estimated performance bucket, not a guarantee you are on mobile data. Fast Wi-Fi can still report a “4G” class. Use the interface type field for Wi-Fi vs cellular when available.
How to read the panel
Open: Chrome or Edge — auto-detect when the API exists.
Type: Check Wi-Fi, ethernet, or cellular on the panel.
Metrics: Review estimated Mbps and RTT when available.
Is your connection slow, unstable, or dropping?
Choppy video, failed calls, and laggy games are not always “not enough Mbps”. Weak Wi-Fi, interference, or high RTT are frequent culprits. Knowing Wi-Fi vs ethernet vs cellular is step one.
This tool shows what the browser believes about your network right now. Pair it with ping tests and, when needed, a full ISP speed test. Re-check after you change Wi-Fi bands (2.4 vs 5 GHz) — the browser report updates when the OS switches interfaces.
Tips to stabilize everyday internet
- Sit closer to the router or use ethernet for important calls and games.
- Reboot modem/router; install firmware updates when offered.
- Change Wi-Fi channels if neighbors crowd the spectrum.
- In larger homes, mesh usually beats cheap single repeaters for dead zones.
- Put IoT devices on a guest network if they saturate the main SSID.
- On phones, stick to trusted Wi-Fi instead of flapping onto weak 5G.
- Pause cloud backups and OS updates during meetings.
- If wired speeds never match the plan, open a ticket with evidence.
Wi-Fi vs 4G/5G: what actually matters
Good Wi-Fi on local fiber often wins on RTT and call stability. Cellular wins on mobility but suffers from tower load and handoffs.
If the panel shows cellular when you “thought it was Wi-Fi”, the device may have fallen back to mobile data — common on flaky guest networks.
If you work from home, a single weak wall between the router and your desk can turn a fiber plan into a choppy video call. Moving the access point one room closer often beats buying more advertised megabits.
High Mbps but still feels slow
Throughput (Mbps) and latency (ms) are different. You can have 300 Mbps and high RTT. Games and calls care about latency and loss; large downloads care about Mbps.
The API reports estimates, not a multi-server speed test. Treat it as a quick thermometer of what the browser thinks.
Mesh, repeaters, and changing ISPs
Cheap repeaters often halve throughput. Well-placed mesh keeps roaming cleaner in larger apartments.
If wired speeds never approach the plan, the ISP link may be the issue — compare fiber options with peak-hour measurements.
Privacy
Network Information API values are read locally for display. We do not need your LAN details uploaded to “process” the panel you see.
When network gear or a new plan enters the chat
If the home has Wi-Fi dead zones, quality mesh changes daily life more than another magic “booster” app. If ethernet never hits the contracted speed, that is an ISP conversation — not a router upsell. Use panel readings and repeated tests to decide.
