Reduce congestion and channel overlap
In crowded apartments and colonies, dozens of routers fight over the same airwaves.
- In your router settings, change the Wi-Fi channel for the 2.4GHz band to 1, 6, or 11, which do not overlap. Try each and re-test.
- Set the router to "Auto" channel if you do not want to experiment — it picks the least busy one.
- Disconnect devices you are not using. Idle phones, tablets and smart bulbs still consume bandwidth with background updates.
- If your router supports it, turn on QoS (Quality of Service) and prioritise video calls or streaming over downloads.
Secure your network so nobody else slows it down
An open or weakly protected Wi-Fi means neighbours may be using your bandwidth.
- Use a strong WPA2 or WPA3 password, not the default printed on the router.
- Change the default admin login for the router settings page.
- Check the list of connected devices occasionally; if you see something you do not recognise, change the password.
