Tim, The update issue to 13.2 from 13.1.3 was addressed in the release notes. The recommended deployment method is to upgrade SM’s to 13.2 first followed by the AP. This prevents the 8X/1X issue.
I believe the lower modulation rate is due to the new version being less aggressive in moving to the higher modulation rates. I believe it prefers lower bit error rates over higher modulation. I don’t really consider that a defect. We have not see the DNS issue. We run NAT with the DNS servers manually specified in the SM’s. Mark > On Nov 26, 2014, at 7:09 PM, Timothy D.
