How to fix “Wi-Fi is slow” on your devices
Pages load slowly or videos buffer? These tweaks usually bring speeds back. Written for your devices, with your ISP-provided router in mind.
More than one device is affected — that almost always points at the router or the internet connection itself, not any single device. Start at the network end.
Slow Wi-Fi usually comes down to distance, interference, or one device hogging all the bandwidth. A few simple tweaks fix most cases.
Run a quick speed test before and after each change so you can see what actually helped.
On an ISP-provided router
Settings are often partially locked to your provider, and they can sometimes restart or re-provision your line remotely — a quick call may be the fastest fix. Support details are usually on the router’s sticker.
Your step-by-step fix
1Test one device near the router and one further away — this tells you whether the problem is coverage or the connection itself.
2Move closer to the router and test again. If speeds jump, the problem is range — see the weak-signal steps.
3Pause large downloads, uploads, streaming on other devices, and backups, then retest.
4Restart your router: unplug it for 30 seconds, plug it back in, and wait for it to reconnect.
5Place your router somewhere central, up high, and out in the open — not on the floor or inside a cabinet.
6If slow speeds only happen in one room, consider a mesh Wi-Fi system for even coverage.
Speed tests are most accurate when run near the router and repeated a couple of times.
Older devices can drag a whole network down — check whether the slowness follows one device.
Your provider’s plan sets the ceiling: if a wired test is also slow, the limit isn’t your Wi-Fi.
If every device went offline at the same moment, look at the router first: it’s rarely a coincidence.
Fix the network-level problem once and every device recovers together — no need to repeat device steps everywhere.
