Thanks, all. I should have seen that bit about iwconfig being included with the wireless tools extension - was jumping around in the doc too much (getting ADD as I get older ;-)
Robert, where is "appsbrowser"? [Never mind - finding/reading more docs, I see it is available within TC, but that is a sort of Catch-22 in needing TC running to see how to modify it (at least for networking that is pre-req to everything that is obtained over the network). Guess I should look around to see if its equivalent function is on these TC-related websites?]
TIA,
Rory
