Before You Call Your ISP: A Connectivity Troubleshooting Checklist

Why Most Connection Problems Start at Home

When your internet drops or slows to a crawl, the instinct is to call your ISP. But the vast majority of everyday connectivity problems — dropped signals, sluggish speeds, pages that refuse to load — originate somewhere inside your home, not at the provider's end of the line.

Working through a short checklist before you call can save you 30 minutes on hold and often has your connection back up in under ten minutes. This guide walks you through every layer of a home network, from the physical cable coming into your home to the device in your hand, in the order that makes troubleshooting most efficient.

If you run into unfamiliar terms along the way, our internet connectivity glossary explains the most common networking vocabulary in plain language.

The Checklist

Work through these steps in order. Each group builds on the last, so resist skipping ahead — you may solve the problem earlier than you expect.

If you share your building's internet infrastructure — common in apartments and rentals — some of these steps may not fully apply to your setup. Our guide on home internet for renters explains the extra variables worth knowing about.

When the Checklist Doesn't Fix It

If you've worked through every item above and your connection is still unreliable, that's actually useful information: it means the problem is likely outside your home equipment. At this point, calling your ISP is the right move — and you'll be prepared with specific observations (what you tested, what the results were) that help support agents diagnose the issue faster.

Persistent slowness rather than a full outage is a different problem. If your connection technically works but feels consistently undercooked, diagnosing a slow internet connection covers a more systematic approach to identifying whether your plan, your router placement, or device behaviour is the real culprit.

Smart home devices that keep dropping off your network often point to the same underlying issues covered here. See our article on why smart home devices stop responding for more context on how network health affects connected gadgets.
