Sorted! And you're not going to believe how I did it. In fact I'm not quite sure myself. To make a bit of room to get at the gubbins in the cube once more, I had to take an E-mac off my desk that had been there for a couple of weeks while I sorted it out ready for my business. As soon as I moved it Voila - problem solved. The rear of the E-mac was pointing at and about 6 inches away from the cube. I'm thinking that maybe there was some unshielded Rf (CRT maybe_ emitting at a specific frequency and disturbing the network. The E-mac has no airport card, was not hard-wired to the network, no peripherals shared with the cube and the only cable out of it was the power cable to a shared socket with the cube. In the interests of pure science, I stuck it back on the desk and powered up and hey-presto, lost my network. Who would have though? Since taking it away and boxing it up to go to the office, I have had a steady 4 bars on my airport signal and no snags at all. I know the E-mac must be shielded as it can use airport itself but maybe there's unshielded areas? Or maybe it was down to pure jealousy on the E-macs side of things? Thought the cube was too damn sexy to just sit there without getting some high-frequency abuse!! Well there you go. Another one to add to the list of possible fixes for the future.
