Wi-Fi slow at home? Fix these things before calling your provider

Most slow home Wi-Fi is caused inside the house, not by the internet plan.

1. Restart the router and modem, then test speed near the router
2. Move the router to a central, raised spot away from walls and the microwave
3. Use the 5GHz band for devices near the router and 2.4GHz for far rooms
4. Change the Wi-Fi channel in router settings if neighbours crowd yours
5. Update router firmware from its admin page
6. Check for unknown devices using your network and change the password

When to upgrade

If speed is fine next to the router but poor in far rooms, a mesh system or a second access point helps more than a faster plan.

Test properly: run a speed test with your phone right next to the router, then in the room where it feels slow. If the first number is fine and the second is not, the problem is coverage, not your plan.

First, find out where the problem is

Run a speed test on your phone right next to the router, then in the room where it feels slow, and finally with a laptop connected by an Ethernet cable if you can. If the cable test is fast and the far room is slow, your plan is fine and the problem is Wi-Fi coverage. If even the cable test is slow, contact your provider.

Why walls and floors matter so much

Many Indian homes have thick brick or concrete walls that absorb Wi-Fi signals, especially the faster 5GHz band. A router tucked inside a cupboard or at the far end of the house can leave other rooms with weak signal even on an expensive plan.

2.4GHz vs 5GHz in simple words

• 2.4GHz travels further and through walls better, but is slower and more crowded
• 5GHz is much faster at short range, but weakens quickly through walls
• Many routers combine both under one name; if yours shows two names, connect nearby devices to 5GHz

Fixes that cost nothing

1. Move the router to a central, open spot about chest height
2. Point external antennas in different directions, one vertical and one horizontal
3. Restart the router once a week if it gets sluggish
4. Change the Wi-Fi channel in router settings if many neighbours' networks are visible
5. Disconnect devices you no longer use and change the password if you suspect strangers

When to spend money

For large homes or multi-floor houses, a mesh Wi-Fi system with two or three units gives the most even coverage. A simple range extender is cheaper but often halves speed. If your router is many years old, a newer Wi-Fi 6 router improves speed and handles many devices better.

Frequently asked questions

Why is my Wi-Fi slow only at night? Many people in your area are online at the same time, so the provider's network gets busy. A cable test at night helps confirm this.

Does the number of devices matter? Yes. Smart TVs streaming in 4K, phones backing up photos and game downloads all share the same connection.
