Slow or broken internet isn't always your ISP's fault. Work through this checklist to diagnose issues on your side of the connection first.

Key Takeaways

  • Most home internet problems originate inside the house, not at the ISP level.
  • Rebooting your modem and router resolves a surprisingly high number of connectivity issues.
  • Wi-Fi signal drops off significantly through walls, floors, and with distance from the router.
  • Too many devices competing for bandwidth can slow every connection on your network.
  • A single bad ethernet cable or loose coax connection can mimic a full outage.

Why Your Home Setup Is Usually the First Place to Look

When the internet stops working or slows to a crawl, the instinct is to call your provider and wait on hold. But in many cases, the problem is sitting right in your home — and it can be fixed in minutes without a service call.

Your internet connection is made up of several layers: the physical line coming into the house, the modem that translates that signal, the router that distributes it, and the devices you use. A weak link anywhere along that chain can make everything feel broken — even when the ISP is delivering a perfectly healthy signal to your front door.

This checklist walks you through the most common causes of home internet trouble, in roughly the order you should check them. For a deeper look at how each piece fits together, see our guide to your home network end to end.

Hardware and Physical Connections

Reboot your modem and router by unplugging them, waiting 30 seconds, and plugging the modem back in first — then the router after it fully restarts. Must
Check that all cables going into your modem and router are firmly seated — a slightly loose coax or ethernet cable is a common culprit. Must
Look for any indicator lights on your modem that are red, blinking unusually, or missing entirely — your modem's manual or the manufacturer's website will explain what each pattern means. Must
Swap out the ethernet cable between your modem and router if you have a spare — cables can fail internally without any visible damage. Should
Confirm that your modem and router are in a well-ventilated spot and not inside a cabinet, closet, or stacked under other electronics that could cause overheating. Should

Wi-Fi Signal and Placement

Move closer to your router and test the connection — if speed improves dramatically near the router, distance or interference is likely the issue, not the service itself. Must
Check whether other devices in your home have the same problem — if one device struggles but others work fine, the issue is with that specific device, not the network. Must
Reposition your router away from microwaves, cordless phones, and baby monitors, which can all interfere with 2.4 GHz Wi-Fi signals. Should
If your router supports both 2.4 GHz and 5 GHz bands, try switching your device to the other band — 5 GHz is faster but shorter range, while 2.4 GHz reaches farther but is more prone to interference. Should
Consider whether walls, floors, or large metal appliances are blocking the signal path between your router and the struggling device. Nice to have

Device and Software Checks

Restart the device that's having trouble — this clears stale network settings and is the single fastest fix for device-specific connectivity problems. Must
Check whether a VPN is running on the affected device — VPNs route your traffic through additional servers and can significantly slow your connection. Must
Disconnect any devices that are actively downloading updates or streaming in the background, then retest your speed — bandwidth-heavy background activity affects everyone on the network. Should
Run a browser-based speed test from a device connected by ethernet cable to get a clean baseline reading that isn't affected by Wi-Fi conditions. Should
Check whether your device's network adapter drivers are up to date, particularly on Windows PCs — outdated drivers can cause intermittent disconnections. Nice to have

Network Load and Settings

Count how many devices are currently connected to your network — a busy household with 10–15 active devices can easily saturate a lower-tier internet plan. Must
Log into your router's admin panel and confirm it hasn't been set to a low bandwidth limit or that Quality of Service (QoS) settings aren't accidentally deprioritizing your main device. Should
Check whether your router's firmware is up to date — manufacturers release updates that fix bugs and improve performance, and many routers don't update automatically. Nice to have

Tools You'll Want Nearby

You don't need any specialized gear to run through most of these checks, but a few things will make the process faster.

Required

Smartphone or laptop

Used to run speed tests and compare connectivity across multiple devices.

Required

Ethernet cable

Lets you connect a device directly to your router to isolate Wi-Fi issues from broader network problems.

Required

Speed test website (e.g., fast.com or speedtest.net)

Measures your actual download and upload speeds so you can compare them against your plan's advertised speeds.

Optional

Router admin app or web interface

Allows you to see connected devices, check firmware version, and review QoS or bandwidth settings.

If you're adding new devices to your network and are concerned about whether it can handle the load, our smart device setup readiness checklist walks through capacity and placement considerations before you plug anything new in.

Don't Reset to Factory Settings Just Yet

A full factory reset on your router wipes all your custom settings — including your Wi-Fi name, password, and any port forwarding rules. It should be a last resort, not an early step. Try rebooting and working through this checklist before reaching for the reset button.

When to Actually Call Your Provider

Once you've worked through this checklist and everything on your end checks out, that's when a call to your ISP is genuinely warranted. Before you dial, it helps to have a few things ready: the results of a speed test, the model numbers of your modem and router, and a clear description of when the problem started and whether it affects wired and wireless devices equally.

Providers can run remote diagnostics on the line coming into your home. If they detect a signal problem on their end, they can schedule a technician. If they don't, you'll at least have ruled out the most common home-side causes — which puts you in a much better position to push for a real answer.

Speed Test Results Can Be Misleading

Speed tests measure the connection between your device and a remote server — and results vary depending on server location, time of day, and whether you're testing over Wi-Fi or ethernet. Always run a wired speed test for the most accurate reading, and test at different times before drawing conclusions about your service quality.
