One click, every lag check
Find and fix your lag in one go
Boost starts with the seven lag checks ticked: this device, speed and lag under load, DNS, the spike finder, game servers and routes, the connection check and video calls. Then it gives you one list of fixes, best first, grouped by where the lag starts. Tick more to add the privacy, streaming and security checks.
Boost: test and optimize my lag
11 checks (speed, lag, Wi-Fi, DNS, gaming, privacy and security) in about 2 minutes, then a step-by-step plan that fixes what we find. Nothing to install.
Optimize for
Kill ping spikes, bufferbloat & packet loss
Tick the checks you want, or press Test on any one to run it on its own.
Speed & lag
Home & device
Gaming & calls
Privacy & security
Want one check on its own? Every tool has its own page: see all tools. Boost lowers lag by finding bottlenecks; it can't make your plan faster than what you pay for.
Who Boost is for
Boost is for the moments when the connection feels slow but the speed test looks fine: ping that jumps in a match, a video call that freezes when someone else starts a download, or pages that hesitate before loading. Those problems usually come from delay, not from a lack of speed, and they start in different places: your device, your Wi-Fi, the queue in your router, DNS or the route to a server. Boost measures each of these in turn and puts the fixes in the order that removes the most lag first.
Common questions
What is the difference between Boost and Test & Optimize?
Boost starts with only the lag checks ticked, so it is quicker and aimed at games, calls and streaming that stutter. Test & Optimize starts with every check, including privacy leaks, open ports and security, and builds a wider plan. You can tick extra checks in Boost at any time.
Why does Boost run the checks one after another?
So they never compete for your line. A speed test running at the same time as a ping or DNS test would make both look worse than they are. Running them in turn keeps each number honest, which matters when you compare before and after a fix.
Will Boost change my router or device settings?
Not on its own. It measures, then lists fixes in order of impact with the exact values to use. We ask before anything that changes your router, device or DNS, and the fix guides walk you through each change step by step.
How do I get the most accurate Boost result?
Run it on the device that has the problem, ideally once on Wi-Fi and once on a cable, and close large downloads first. Then make one change, run Boost again and compare. A fix that worked shows up in the same test.
