Environment:
- Fulfillment Center (215,000sqft)
- 26x AP 134's 3x AP214
- Controller ArubaOS (MODEL: Aruba3600-US), Version 6.4.2.18
- RF Devices: Motorola MC3190, MC32N0, WT41N0
Summary:
These HHD's (hand held devices) have historically been problematic with users reporting wireless connectivity issues (dropping of the network). I have scoured these Airhead threads to find input and have tried all advice in this thread:
https://community.arubanetworks.com/t5/Wireless-Access/Constant-dropouts-for-our-Motorola-Symbol-Scanners-MC9090G/td-p/241524
and additionally put my ARM g and a into Maintain mode
Interesting log statements:

We experience these drop offs every day. Sometimes they effect the work stream more sometimes less... Any help is welcome!
Thanks,
