Why is my internet so slow, and how do I actually fix it?

Compare wired and Wi-Fi speed tests to isolate whether the ISP, router, or placement is slowing the connection.

Test the connection in stages—first wired into the modem, then over Wi-Fi beside the router, then in the slow room. The difference between those results tells you whether the bottleneck is the internet service, the router, or the radio signal reaching your device. Without those measurements, upgrading a plan or buying random hardware is mostly guesswork.1.

Establish the ISP baseline. Connect a laptop directly to the modem or gateway with Ethernet, pause large downloads and streaming on other devices, and run speedtest.net. Note download speed, upload speed, and latency.

This is the closest practical view of what the provider delivers.2. Measure the Wi-Fi penalty. Run the same test beside the router, then in the room where service feels slow.

Strong wired speed but weak nearby Wi-Fi points to the router or its settings; a big drop only in the distant room points to placement, walls, or interference.3. Reboot in the right order. Unplug the modem and router for 60 seconds.

Plug in the modem first and wait until its connection lights settle, then power the router. This forces a clean link rather than simply restarting both at once.4. Improve placement.

Put the router near the center of the home, around chest height, in the open. Avoid metal cabinets, thick masonry, aquariums, and microwave ovens. A mesh node should sit between the router and dead zone, not inside the dead zone.5.

Update and assess the router. Install current firmware. A single-band model more than about five years old can be the limiting factor, especially with many devices.6.

Call with evidence. Saying “I get 45 Mbps wired on a 300 Mbps plan” is more actionable than “it feels slow.”Pro tip: replace an old router before buying a faster plan. As multi-gig fiber hardware such as Nokia’s 50G line cards rolls out, your home network still has to be capable of using the speed you pay for.
