How can I begin troubleshooting my home network with Wireshark? I’ve installed it but am unsure what to look for in the traffic logs

Start with these basics:

  1. Capture on the right interface - Usually your main network adapter (Wi-Fi or Ethernet). Test with a simple ping to google.com first.

  2. Use display filters - Start with icmp to see ping traffic, or http for web browsing. This narrows down the flood of data.

  3. Look for obvious problems - Red/black packets indicate errors, excessive retransmissions, or connection timeouts.

  4. Check response times - Slow DNS responses or high latency between request/response pairs.

For home networks, Wireshark often shows you have a different problem than expected. Most “network issues” are actually Wi-Fi interference, ISP problems, or device-specific issues that won’t show up clearly in packet captures.

Start simple: Can you ping your router? Can you reach external sites? Wireshark is overkill for most home troubleshooting - try basic network tools first.
