I'm unable to connect any of my devices to my home Wi-Fi network. It shows up in the list, but when I try to connect, it says 'Authentication problem' or just fails.

For larger homes with many devices, a mesh Wi-Fi system can provide better coverage and manage network traffic more efficiently.

Reduce the number of devices actively using the internet at the same time, especially for bandwidth-intensive activities.

Access your router's settings and try changing the Wi-Fi channel to one that is less congested.

Try turning off other electronic devices one by one to see if the Wi-Fi signal improves.

Ensure your current router's firmware is up-to-date, as updates can sometimes improve performance.

Consider purchasing a newer router that supports Wi-Fi 6 or Wi-Fi 6E for improved speed and range.

Clear any large furniture or appliances that might be directly between the router and the weak signal areas.

Move the router to a more central location in your home, away from obstructions and at a higher elevation if possible.

If the outage is prolonged and no information is readily available, contact your ISP to confirm if it's planned maintenance.

Check for any prior notifications from your ISP about scheduled maintenance that might be affecting your area.
