Wi-Fi keeps dropping or slow in the evening? Change the channel
In flats and busy streets, your Wi-Fi shares the air with your neighbours'. When many networks use the same channel, they take turns – and your Wi-Fi drops out or crawls, often in the evening when everyone is home, and at weekends all day. Changing the channel on your router often fixes it in two minutes.
Why the channel matters
On 2.4 GHz there are only three channels that don't overlap: 1, 6 and 11 (in Europe 1, 5, 9 and 13 also work). If six networks around you sit on channel 6 and none on 11, moving to 11 gives your Wi-Fi room to breathe. 5 GHz has many more channels and walls stop the neighbours' signal, so it is usually less crowded – but it reaches less far. In big-city blocks with hundreds of networks, 2.4 GHz can be crowded around the clock – there, switching to 5 GHz (or 6 GHz on newer routers and phones) and a good router position help more than any channel.
First try: restart the router at a quiet time
Most routers pick their channel automatically when they start. Restart yours when the neighbours' Wi-Fi is quiet – late at night or early in the morning on a weekday, not in the evening rush or at the weekend – and it often picks a better channel by itself.
Find the quietest channel with NetPin
NetPin (Android) shows your Wi-Fi strength, band and channel for free. In the full version (30 days free) it lists the Wi-Fi networks nearby, counts how many share your channel and tells you which one is quieter.
How to change the channel on your router
- Connect to your Wi-Fi and open the router's address in a browser (it is printed on the label, often 192.168.1.1 or 192.168.0.1).
- Log in with the admin password from the label (not your Wi-Fi password, unless the label says so).
- Find the Wi-Fi / Wireless settings. If there is an automatic channel option (Auto, Smart Wi-Fi, Channel optimisation), switch it off first.
- Pick the channel NetPin suggests for 2.4 GHz (1, 6 or 11), save, and wait a minute while the router restarts its Wi-Fi.

Menus differ between models and firmware versions. If your router looks different, search for your router's name plus “change Wi-Fi channel”, or ask your provider.
Your router has no channel option?
Some provider routers choose the channel themselves and hide the setting. You can still help your Wi-Fi:
- Use the 5 GHz network if your phone sees one – it is faster and less crowded.
- Put the router high up, in the open, near the middle of your home – not in a cupboard or behind the TV.
- Restart the router at a quiet time so it picks a free channel.
- For large homes: a mesh system or your own router, where you can choose the channel.
