Should I use 2.4 GHz or 5 GHz Wi-Fi?

2.4 GHz usually reaches farther and passes through obstacles better. 5 GHz is often faster and less crowded at shorter range. Let band steering choose when it works reliably.

Where should I place a Wi-Fi extender?

Place it between the router and the dead zone, where it still receives a good signal. An extender installed inside the dead zone has little useful signal to repeat.

Will a faster internet plan fix weak Wi-Fi?

A faster plan increases the connection available at the router but does not fix poor coverage, interference or a badly placed router. Test near the router first.

Step 01 / 06

Record where the signal is weak

Test the same device near the router and in each problem room at similar times; note speed and dropouts. Check a second device. Pause large downloads during comparisons. If all devices are slow even nearby, compare with Ethernet if available and check your provider for an outage before buying Wi-Fi equipment.

Test the same device near the router and in each problem room at similar times; note speed and dropouts. Check a second device. Pause large downloads during comparisons. If all devices are slow even nearby, compare with Ethernet if available and check your provider for an outage before buying Wi-Fi equipment.
2. Restart and update the equipment

Restart the modem and router in the manufacturer's order and wait for each to reconnect. Back up settings before making changes. Install firmware only through the official app or administration page; do not interrupt its power. Avoid factory reset unless you have connection details and intend to set everything up again.
3. Move the router to a better position

Place the router in an open, central and raised position where possible. Keep it away from metal cabinets, floors, thick masonry, aquariums and large appliances. Avoid enclosing it or covering its ventilation openings.
4. Reduce radio interference

Separate the router from microwave ovens, cordless-phone bases, baby monitors and crowded Bluetooth equipment. Try automatic channel selection first. Keep supported bands enabled: 2.4 GHz usually reaches farther; 5 GHz or 6 GHz can perform better nearby on compatible devices. Band steering can help devices select a suitable band.
5. Retest before adding equipment

Repeat the same tests in the same places after each change. If only one device has trouble, update or troubleshoot it. Before forgetting and rejoining Wi-Fi, make sure you know the password. If Ethernet is also consistently slow, troubleshoot the internet connection with your provider.
6. Choose an extension method if needed

For remaining dead zones, consider an Ethernet-connected access point or a compatible mesh system. Place wireless mesh nodes or extenders where they still receive a strong upstream signal, not inside the dead zone. Follow the maker's setup to avoid competing routers. Use WPA3 Personal or WPA2/WPA3 transitional security and a strong password; retest coverage.
