Copper Goose

When your internet gets slow or keeps dropping, the hard part is finding the cause — your own kit, or the company you pay every month. Copper Goose Network Monitor answers that in a sentence, not a chart.

It runs quietly in the background on Windows 10 and 11 and learns what your line normally does — the speed it settles at, how far latency wanders, jitter, how your router behaves under load. Warnings come from departures from that, so it works the same from rural DSL and satellite to gigabit lines, nothing to configure or manually enter.

When something goes wrong it names the part at fault: a weak Wi-Fi link, an Ethernet cable that has quietly dropped to a slower speed, a router that stopped answering, the fibre box on the wall (ONT), or the ISP's own line.

Every episode is recorded with the time, how long it lasted and the measured figures, and the log exports as a report — so instead of "it feels slow" you can say "it dropped at 9:14, 9:47 and 10:30 three nights running, at 45 Mbps against a usual 200."

It also tracks your data usage against a limit you set, warning you at 80% and 100%, and shows live throughput. Free for 14 days, then a one-time purchase, no subscription ever, 7-day money-back guarantee, code-signed installer, light and dark themes.
