Trying to listen/see traffic between two pieces of equipment from my laptop. I am using a Hub, Wireshark is in promiscuous mode. Yet, I can not see any traffic other that what is going to/from my laptop. The two pieces of equipment are not computers but do have network cards along with assigned IP addresses. My laptop is running XP with a Broadcom NIC.

What am I doing wrong?

If you are sure that the two "non-PCs" do talk to each other while you take your capture, my conclusion is that the box you are using may bear a label reading "HUB" but it actually works as a switch. Also, you may have used one of those so-called "rate-adapting" hubs which internally worked as two independent hubs, one 10 Mbit/s and one 100 Mbit/s, and a bridge (switch) between the two.

Monitor mode of network adaptors is only relevant for wireless adaptors and on these, for operating systems other than Microsoft Windows.

sindy, you are exactly right when you typed "my conclusion is that the box you are using may bear a label reading "HUB" but it actually works as a switch", we pulled out an old HUB made in the previous century and everything went to working perfectly.

Thanks for the response.
