While this is not showing up on the US DLink support site, it is a WW firmware release and I've found it working in my USA setting without any regressions for the last three weeks.
Version 1.14B06 - http://www.dlink.com/uk/en/support/product/dap-1665-wireless-ac1200-dual-band-access-point
From the release notes all this added was WW signal strength adjustments, but it's several builds since 1.13B05 so I expected devs to have slipped in some fixes. I did find it finally fixed the problem with the log page numbers being incorrect yay. But nothing else of note.
My previous experience with the DAP-1665, in that it spontaneously reboots with more than 15 mixed 11n/ac clients attached, persists. I continue to use it only for 5Ghz 11ac clients where it performs adequately and have employed a DAP-1522-B1 handling 2.4Ghz 11n clients in a retail business setting.
But if you would like to be able to read the logs without the missing pages, then this version does finally fix that. Use at your own risk/discretion, or even better contact DLink to make this available formally in the USA/Canada since it does fix at least one problem.
