How to fix “Wi-Fi is slow” on your iPhone or iPad
Pages load slowly or videos buffer? These tweaks usually bring speeds back. Written for your iPhone or iPad, with your ISP-provided router in mind.
These steps are written for an iPhone or iPad running a recent iOS or iPadOS. The router-side fixes apply to any device on your network.
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
1On your iPhone or iPad, open Settings → Wi-Fi, tap the ⓘ next to your network, and check what it says about the connection.
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.
iOS quietly joins known networks again after a forget — tap “Join This Network” manually and re-enter the password when prompted.
Low Data Mode (the toggle in the network’s settings) can make things feel broken — turn it off while troubleshooting.
