Log in to your router (usually 192.168.0.1, 192.168.1.1 or 192.168.8.1; check the sticker underneath), open Wireless or WLAN settings, and change the channel from Auto to a specific channel. On 2.4 GHz use 1, 6 or 11, whichever is least used by neighbours. On 5 GHz, pick any free channel. Save, and your devices reconnect within a minute.

02Finding the best channel
Install a Wi-Fi analyser app on an Android phone. It shows every network nearby and its channel. Pick the channel with the fewest and weakest neighbours.
| Band | Channels to use | Why |
|---|---|---|
| 2.4 GHz | 1, 6, 11 | Only these three don't overlap |
| 5 GHz | Any free one, e.g. 36–48 or 149–161 | Many non-overlapping channels |
03Still slow?
A better channel helps in crowded apartments, but not with thick walls. See how to improve your Wi-Fi signal.
04Frequently asked questions
What is the best Wi-Fi channel?
On 2.4 GHz, whichever of 1, 6 or 11 is least crowded where you are.
Will changing the channel disconnect my devices?
Briefly; they reconnect automatically.
Should I leave the channel on Auto?
Auto often works, but in busy apartments a fixed, less crowded channel is usually better.
