Why Is My Internet So Slow?
Slow internet isn’t always your ISP. It’s often Wi-Fi placement, device overload, or one app hogging bandwidth. Use this step-by-step guide to pinpoint the culprit fast.
Step 1 — Run a Speed Test (the right way)
- Plug a computer directly into your modem or router with an Ethernet cable (if possible).
- Open Chrome, Safari, or Edge.
- Go to speedtest.net or fast.com.
- Click Go/Start and wait ~30 seconds.
- Record:
- Download — streaming and browsing
- Upload — video calls and sending files
- Ping/latency — responsiveness for calls and gaming
Repeat morning, afternoon, and evening. Big evening slowdowns = likely provider congestion.
Step 2 — Compare Wired vs. Wi-Fi
- Wired fast, Wi-Fi slow → wireless setup is the issue.
- Both slow → suspect the ISP or modem.
Step 3 — Fix Common Wi-Fi Issues
Placement
Keep routers central and high. Avoid closets — metal and concrete kill signal.
Interference
Microwaves, cordless phones, and neighbor Wi-Fi overlap. Change channels if needed.
Right Band
2.4 GHz = longer range/slower. 5 GHz = faster/shorter range. 6 GHz = newest, fastest if supported.
For larger homes or offices, we deploy Ubiquiti UniFi Mesh access points so every room gets consistent coverage and speed.
Step 4 — Count Your Devices
It’s common to have 20+ connected devices: PCs, phones, TVs, cameras, printers, consoles, smart speakers. Many use bandwidth in the background.
Consumer routers struggle here. Ubiquiti UniFi routers/firewalls handle higher device counts and let us prioritize work traffic over streaming.
Step 5 — Find Bandwidth Hogs
- Updates — Windows, iCloud, or Microsoft 365 downloads
- Cloud sync — Dropbox or Google Drive moving large folders
- Malware — infected PC flooding the connection
Quick test: power off devices one by one. If speeds jump, you found the culprit.
Step 6 — When It’s the ISP
- Peak-time slowdowns
- Outdated modem or wiring
- Plan mismatch — 100 Mbps split across 25 devices will crawl
Run a speed test at the modem. If that’s slow too, call your ISP and ask about a modem refresh or plan upgrade.
Step 7 — Call the Pros
- 24/7 network monitoring to pinpoint slowdowns
