Why Is My Internet Slow on Only One Device?
When every device in your home works fine except one, your internet connection isn't the problem — that specific device is. This is actually good news, because device-level issues are usually quick to fix. Here's how to pinpoint it.
Confirm it's really just one device
Run a speed test on the slow device, then on another device on the same network. If the second device is fast, you've confirmed it's device-specific. If both are slow, the issue is your WiFi or internet, not the device.
The most common causes
- Too many background apps — updates, cloud backups and sync quietly eat bandwidth.
- The device is on 2.4GHz while others use the faster 5GHz band.
- Distance from the router — that device may be further away or behind more walls.
- An old or full device — low storage and aging hardware slow everything, including networking.
- A VPN or proxy running only on that device.
- Malware using bandwidth in the background.
Step-by-step fixes
Reboot the device, close background apps, forget and rejoin the WiFi network (ideally the 5GHz band), move closer to the router, disable any VPN to test, update the OS, and free up storage. Re-test after each step.
