Noise and tunnels

I originally brought up the problem with "Searching for Gateways" over six months ago and wrote a brief article on it http://www.moskaluk.com/attempting_to_connect_gateway.htm

Since then the problem has appeared and reappeared and I'm not closer to the answer. Lately on the Locustworld mail list I posted the question and it getting better response then it did six months ago. It looks like I'm not the only one. The latest thinking about "Searching for Gateway" is a brief interruption due to radio overlap of another device. This cause the tunnels in wireless Mesh to stop communicating. After a while the tunnels reset themselves and everything goes back to normal.

The question is how do the tunnels establish themselves and is there away to force the issue?

I'm glad that many more people are on top of this problem. We many finally get resolution.
