Forgive my ignorance, but is this 'cloaking' you speak of, a feature of 802.11G, or is it exclusively starOS, or can I find in in Mikrotik as well??

I won't join into the arguement of B versus G and Amp versus no amp, but I will say.... I got three links working last week, using Cloaking, that were not able to be made work without Cloaking ability. When I can make a software parameter change and go from bad link to good link, thats something that can not be ignored.
