Network Monitor

Is your internet dropping out? A network monitor is a tool that continuously checks whether a connection is up, the way running ping 8.8.8.8 in a terminal does, but with a live visual dashboard and no command line. Press Start below and leave this tab open. The monitor checks your connection every few seconds, flips to a red Disconnected state the moment it drops, and logs every outage with a timestamp and how long it lasted, so you can prove an unstable connection to your ISP.

Idle

Press Start to begin monitoring your connection

How it works: browsers cannot send a real ICMP ping, so this tool sends a tiny web request every 2s and measures the round-trip. A request that fails or exceeds 5s is logged as a connection drop. Keep this tab open to watch your connection over time. Everything runs in your browser, nothing is stored.

How to Monitor Your Connection

1. Start

Pick a check interval (1s is most sensitive) and press Start monitoring.

2. Leave it open

Use your connection normally. Keep this tab open in the background while you work, call, or game.

3. Read the log

Check the uptime %, drop count, and outage log to see when and how long your internet dropped.

Speed Is Not the Same as Stability

A fast connection can still be unreliable. Bandwidth (measured by a speed test) tells you how much data you can move per second, but it says nothing about consistency. Video calls freeze, games rubber-band, and pages stall because of latency spikes, jitter, and brief drops, not low speed. This monitor is built to catch exactly those short interruptions that a one-off speed test misses. For a breakdown of what ping and jitter numbers actually mean, see our guide to reading a speed test.

Isolating the Cause: Router, Wi-Fi, or ISP

Wired vs Wi-Fi

Run this monitor over Ethernet and over Wi-Fi on the same device, one after another. Drops that only show up on Wi-Fi point to wireless interference or router placement, not your ISP.

Compare against cellular

Open this page on a phone using mobile data instead of Wi-Fi and run both monitors side by side. If only the home connection drops, the problem is local (router, modem, or line), not a widespread outage.

Look for a time pattern

Drops clustered around evening peak hours usually mean ISP-side congestion. Drops at random times regardless of load point more toward a failing router, a loose cable, or overheating hardware.

Frequently Asked Questions

What does this network monitor do?▾
It continuously checks whether your internet connection is up by sending a small web request every 1–5 seconds and timing the response. When a request fails or times out, it logs a connection drop with the exact time and duration. It is the web equivalent of leaving "ping 8.8.8.8" running in a terminal, but with a simple visual dashboard and no command line.
Is this the same as a real ping?▾
Not exactly. A terminal ping uses the ICMP protocol, which browsers are not allowed to send for security reasons. This tool approximates it with a tiny HTTP request and measures the full round-trip time. The absolute latency numbers run a little higher than raw ICMP ping, but for detecting drops, instability, and outage duration it works the same way and is accurate to within your chosen check interval.
How do I use it to catch an intermittent connection?▾
Press Start and leave the tab open. Set the interval to every 1 second for the most sensitive detection. Then use your connection normally, make a video call, play a game, run a download. When the connection drops, the status flips to Disconnected and the drop is added to the log with a timestamp and duration. Come back later to see how many drops happened and how long they lasted.
Why does it show high latency but my speed test is fast?▾
Speed measures bandwidth (how much data per second); this tool measures responsiveness and stability (how consistently packets get through). A connection can have fast download speed yet still suffer latency spikes, jitter, or brief drops that ruin calls and games. If the timeline shows tall red bars or the drop log fills up while your speed test looks fine, your problem is stability, not bandwidth.
What counts as a connection drop?▾
Any check that fails outright or does not respond within 5 seconds is counted as a drop. Consecutive failed checks are grouped into a single outage so one 10-second dropout shows as one event with a 10-second duration, not several separate ones. The tool also reflects the browser reporting itself fully offline.
Does keeping the tab open use a lot of data?▾
No. Each check downloads only a few bytes, so even at the fastest 1-second interval it uses a negligible amount of data over an hour. The check is cache-busted so it always measures a real round-trip rather than a cached response.
My connection keeps dropping, what should I check?▾
First confirm the pattern here over several minutes. Then: restart your router and modem; if on Wi-Fi, move closer to the router or test with an Ethernet cable to rule out wireless interference; check whether the drops line up with a specific device or time of day; update router firmware; and if drops persist on a wired connection, contact your ISP with the timestamps from the drop log as evidence.
Is my data private?▾
Yes. Every measurement runs in your browser and is displayed only to you. No results are uploaded or saved to any server, and the history is cleared as soon as you close or reload the tab.
How long should I run the monitor to get useful data?▾
At least 30 to 60 minutes for an intermittent issue, longer if the drops feel random or only happen at certain times of day. A single 5-minute run can easily miss a problem that occurs once an hour. For a suspected evening-peak slowdown, start the monitor before the drops usually begin and leave the tab open through the period.
What is packet loss and does this tool measure it?▾
Packet loss is the percentage of data packets that never arrive, distinct from latency (delay) and jitter (inconsistent delay). This tool detects drops and timeouts and reports jitter and latency, which is enough to prove an unstable connection to an ISP. It does not report a raw packet-loss percentage or per-hop detail; that level of diagnosis needs a terminal tool like MTR or traceroute, typically only useful if your ISP asks for it.
