Step-by-Step Solutions to Fix DNS Connectivity Issues

Restart Your Devices

  • To kick things off, a simple system restart can work wonders. Reboot both your computer and router to refresh your network connection.

Disable Antivirus Software Temporarily

  • Occasionally, security software might be overzealous, inadvertently blocking your DNS connections. Temporarily turn off your antivirus to check if it’s the source of the issue.

Flush and Renew DNS Settings

  • Cleansing your DNS cache could resolve stale or corrupted records. Use the Command Prompt to flush the DNS and request new addresses.

Adjust TCP/IP and DNS Configuration

  • Resetting your TCP/IP stack and manually configuring DNS servers can yield a more stable connection. Consider switching to public DNS services from Google or Cloudflare for enhanced reliability.

Switch Up DNS Server Settings

  • Both automatic and manual DNS settings have their perks. If one isn’t working for you, try the other to establish a smooth online experience.

Update Your DNS Service via Router Settings

  • An advanced step involves accessing your router’s admin page and updating the DNS settings directly from the source. This adjustment can benefit all connected devices simultaneously.

Refresh the DNS Service

  • A final trick is to restart the DNS Client service on your machine. This can help clear any service-specific hiccups affecting your internet access.
