Once on line I run Ethereal but to no avail. No matter what I do there seems to be no sign of any packets.

If "once on line" means that you're using a dial-up network connection (or some other PPP-based connection, such as PPPoE or PPPoA), then WinPcap 3.x doesn't support those:

"Version 3.0 beta, 10 feb 03

	o 	NdisWan support:
o due to the large number of messages reporting problems (blue screens) with VPNs, PPTP and such connections, we have disabled the support for NdisWan adapters. As a consequence, it is not possible to capture from PPP (neither NdisWanIp, nor NdisWanBh, nor NdisWanBfIn/Out...). At the moment we have no plans to fix the problem with VPNs, PPTP, PPP unless we get a generous sponsorship."
