How to Fix Slow Internet on Chromebook

Identify and remove the most common causes of slow Wi-Fi or mobile data.

Last verified: February 21, 2026

Slow browsing on Chromebook should be diagnosed at the Chrome browser level first because the majority of tasks on a Chromebook happen through Chrome. Opening chrome://net-internals/#bandwidth shows live bandwidth consumption, and checking whether slowness affects all sites or specific ones rules out website-specific loading issues versus a network-wide problem. Chrome OS doesn't run background processes that consume significant bandwidth by default, so persistent slowness typically points to the Wi-Fi signal quality, router performance, or the ISP's connection rather than the device itself.

Quick Steps

Follow in order for the fastest result.

  1. 1Run a speed test at fast.com and note your download and upload speeds as a baseline.
  2. 2Move within 3 metres of the router or connect via Ethernet to eliminate Wi-Fi signal as the cause.
  3. 3Restart the router and modem: unplug from power for 30 seconds, reconnect, wait 2 minutes, then retest.

Frequently Asked Questions

Why is my internet slow only on Chromebook and not other devices?
Device-specific slowness usually indicates a local DNS cache issue, a VPN or proxy active on the device, background downloads consuming bandwidth, or a driver problem. Flush the DNS cache, check for active VPNs, and check what's using bandwidth in Task Manager (Windows) or Activity Monitor (Mac).
How do I test my internet speed on Chromebook?
Go to fast.com or speedtest.net in a browser. For the most accurate result, close all other apps and browser tabs, connect via Ethernet if possible, and run 2–3 tests. Compare the result against your ISP's advertised plan speed.
Does VPN slow down internet on Chromebook?
Yes. VPNs add encryption overhead and route traffic through an intermediate server, typically reducing speeds by 10–40% depending on the VPN provider and the server location chosen. Disable the VPN and retest if you suspect it is causing slowness.
Why is my Wi-Fi slow at home but fast on other networks?
Your home router may be on a congested Wi-Fi channel. Log into the router admin panel (usually 192.168.1.1) and change the Wi-Fi channel for 2.4 GHz to channel 1, 6, or 11, and for 5 GHz try a higher channel. Also check whether your ISP has throttled your connection or if you've reached a data cap.
