Troubleshooting Slow Internet: A Basic Checklist

Before calling your ISP, a few quick checks can identify whether the problem is really on your end.

Slow internet can come from your provider, your router, your WiFi coverage, or even a single misbehaving device hogging bandwidth. Start by connecting a laptop directly to your modem with an ethernet cable and running a speed test — if it's slow even wired directly in, the problem is likely upstream with your provider.

If wired speed is fine but WiFi is slow, the issue is more likely your router's placement, interference, or an overloaded access point rather than your internet connection itself. Restarting your router periodically also clears up a surprising number of slowdowns caused by memory buildup over time.

If problems persist after these checks, having your provider or IT team check for line noise, outdated firmware, or a router that's simply undersized for your current usage is the next step.

Always make sure you have a current backup before making system changes, and if you're not confident, ask your IT provider to run them for you. Use at your own risk.

Check basic connectivity and response time to a well-known server.
