Actually, I don't think it mattered, I got a forced powercycle last night, with no apparent problems, so I think they are working through area by area until everyone has it
The effect I'm hoping it solves is at the DHCP renew switching to only the first channel(only that channel acrews codewords) for a while (2 hours to a couple days) before all channels begin working again.
I believe this is part of the cause of slowedpageloads/"page not found" (which loads quickly if refreshed) but now I need it to stay active(no reboots or powercycles) for at least 2 DHCP renews to prove it.
I did find under the preivous firmware a powercycle temporarily improved it, and the problem did not appear to be signals or SNR related (always very good here)
Anyway CC must have found enough advantage to having everyone on 1.0.6.8 to push it, in spite of a few remaining issues
maybe in 2 more years...
