title: Wireshark only catches all kinds of packets but I only see ARP, 0x0800, 0x8912, etc. Why do I not see TCP or UDP packets?

  <p>As you can see, Wireshark is definitely capturing a lot of TCP packets. But it is displaying only ARP, 0x0800, 0x8912, etc. If I put TCP as a filter I get blank. Why can't I see TCP packets? </p>
