Run a full system scan with reputable antivirus and anti-malware software to check for any malicious programs that might be affecting your connection.

Ensure the network adapter drivers on your computer are up-to-date. You can usually find these on the manufacturer's website.

Try using a different device (laptop, phone, tablet) on the same network to see if the unreliability persists. This helps determine if the issue is network-wide or device-specific.

If your home is large or has many dead zones, a Wi-Fi extender or a mesh Wi-Fi system can improve coverage and stability.

Identify and move potential sources of interference, such as microwaves, cordless phones, or Bluetooth devices, away from your router.

Place your router in a central, open location, away from other electronics and obstructions. Consider a router placement guide for optimal signal.

Connect your computer directly to the router using an Ethernet cable to rule out Wi-Fi interference or signal strength issues.

Ensure your modem and router are not too old and that their firmware is up-to-date. Consult your ISP or the manufacturer's website for update instructions.

Unplug both your modem and router for at least 30 seconds, then plug the modem back in first, wait for it to fully boot up, and then plug in the router.

Try to conduct important activities during times when network usage is typically lower (e.g., early morning or late at night) to see if performance improves.
