I am in an office with, lets say 20 machines........

I am on machine A running wireshark, connected to hub A......

The slow machine (lets call that B) is connected to hub B. This has no TCP packets showing (or HTTP for that matter, even though I have viewed web pages whilst capturing traffic)

I have captured packets from other machines on hub B, which all have lots of traffic including TCP and HTTP (and yes I'm doing the same things on any machines I'm testing on)

Hub A and B are connected together.

OK, so on which machine are you running Wireshark?  Your machine, one of 
the two other machines you mention, or yet another machine?
