I recently upgraded two R710 to R750 (latest Unleashed), and noticed that AP Info for R750s show pretty high number of %Retries/%Dropped compared to previous R710. For R710 %Retries was 0.0001%, and Dropped was almost 0. But with R750 %Retries is around 27% (even higher for 2.4G). Also PHY errors reported in hundreds, whether in R710 it was mostly 0. There was no changes in environment or AP location.
Interesting that there is absolutely no visible impact on clients, the speed and coverage is excellent, no disconnections.
Any idea what could be causing such high number of %Retries on R750 compared o R710? Thank you!
