At 8:59 a.m., your camera freezes, the meeting chat pops up, “you’re cutting out”, and the only thing moving is the progress wheel. Scenes like this are common across home internet connections, but they’re rarely mysterious. In residential networks, the same handful of issues cause most headaches: slow internet speeds, weak Internet, peak-hour interference, mis-prioritized traffic, or aging hardware.
This article takes a practical, fact-first approach to internet troubleshooting. We break down five problems we see most often at major internet providers and show the fastest sequence to diagnose each one, starting with simple checks you can run in minutes and ending with the moment it’s smarter to call your provider.
-
Slow internet speeds
Confirm whether the problem is your internet or the line itself. Plug a laptop directly into the router with an Ethernet cable and run a reputable speed test. If the wired result looks normal but the internet remains sluggish, the bottleneck is wireless, and you can skip ahead to the next sections. If wired is also slow, power-cycle in this order: unplug the modem or fiber ONT, then the router; wait half a minute; restore power to the modem/ONT and let it fully sync before turning the router back on.
While testing, pause cloud backups and large file syncs so uploads don’t crowd everything else. It’s also worth applying any router firmware update and rebooting cleanly. If a household routinely mixes 4K streaming, gaming, and multiple video calls, moving to fiber internet with higher, and ideally symmetric, speeds removes a common bandwidth ceiling. For bandwidth minimums by activity and number of devices, see the FCC’s Household Broadband Guide.

Weak Internet or dead zones
Wifi is radio, and radio cares about placement. A router tucked behind a TV stand or under a metal desk can lose half its potential before any device connects. Place it high, in the open, and as central in the home as possible; avoid microwaves, big aquariums, or dense shelving. Use bands intentionally: 5 GHz and 6 GHz are faster at short range and ideal for laptops and TVs in nearby rooms, while 2.4 GHz travels farther but tops out at lower speeds and is fine for smart devices in distant corners.
When a device really matters, your main TV, a desktop, a console, one inexpensive Ethernet run removes the guesswork. Larger homes often benefit from a mesh system; if your house is wired for Ethernet, using it as backhaul between mesh nodes greatly improves stability.
-
Congestion and interference at “prime time”
Even well-placed wifi can wobble when every neighbor jumps online after dinner. In your router settings, try different channels to find a cleaner signal; on 2.4 GHz, channels 1, 6, or 11 avoid overlap. On 5 GHz, a bit of experimentation goes a long way.
Keep older cordless phones and baby monitors away from the router. If your router allows separate network names for 2.4 and 5 GHz, give them distinct names so you can deliberately place devices on the band that performs best. Retire old “range extenders” that duplicate your network haphazardly; a properly configured mesh is usually faster.
-
Video calls or gaming that stutter
When web pages load but voice and video fall apart, treat it like traffic control. Many routers offer Quality of Service (QoS); enable it and prioritize your work apps, VoIP, or a specific device so critical traffic doesn’t sit in line behind a game update.
Pause big downloads and auto-updates during meetings. A trusted DNS can make sign-ins and searches load faster, especially on older devices. When reliability matters, plug-in Ethernet outperforms Wi-Fi for a steady connection.
Close background downloads and automatic software updates during meetings. And whenever possible, wire the devices that care most about latency; an Ethernet cable is the most reliable antidote to jitter.
-
Hardware or cabling trouble
Intermittent drops often come down to physical details. Check for loose connections and replace any Ethernet cords that are kinked. Give the router some breathing room; overheating looks like random disconnects. If your router is four or five years old, it may struggle with today’s speeds and device counts; replacing it can be the most cost-effective upgrade you make. If the setup of your system seems off, back up your settings, perform a factory reset, and rebuild the essentials with fresh firmware.
When to call your ISP
DIY ends when a wired speed test stays far below your plan across multiple devices and times of day. When all else fails, call your provider, especially if your warning light on your modem or fiber box comes on, if you see storm damage to the line, or neighbors have the same issue. At that point, provider diagnostics, signal checks, line testing, and a technician visit beat guesswork.
