Looking to the community for any experience and/or advice in regards to the following:
We have a Ruckus Wireless infrastructure utilizing all ZoneFlex 7372 AP's in a single building that is roughly 100,000sq-ft (manufacturing facility). The AP's are controlled by the Ruckus Virtualized Smartcell Gateway-vSCG (VM/Virtual appliance on VMware 5.5).
The AP's are on firmware 184.108.40.206.174
The vSCG is on version 220.127.116.11.174
We are only utilizing 2.4Ghz
Since the day this system was installed, we have experienced horrific connection & roaming behavior with our Intermec CV4’s ranging from application lag and application disconnects. The only application we use on the CV41 is Intermec's ITE (terminal emulation) software to establish a telnet session to our ERP system. The CV41’s are installed on mobile forklift trucks that travel throughout the facility at about 5-10mph on average.
We have been through months of investigation and modifications to both the Ruckus and Intermec systems. Intermec and Ruckus have both all been engaged and onsite to diagnose. The CV41’s have all been updated to their latest respective software levels specifically the Summit client/drivers. We have modified the Summit settings per Intermec and Ruckus recommendations (Ruckus Wireless Intermec Interoperability Guide-rev 1_14.pdf):
Aggressive Roam = on
Radio Mode = “BG rates full” (Only if the 5Ghz band will not be used.)
Power Save = “”CAM”
Tx Power = “Maximum”
Roam Trigger = “-70 dBm” (Set this option to work best for your environment)
Roam Delta = “5dBm”
Roam Period = “5 sec”
BG Channel Set = “1,6,11” (This is optional and should not be set if other channels are used.)
PMK Caching = “OPMK” (Set this if 802.1x is being used)
All recommended DTIM, beacon, etc. settings on the Ruckus side have been modified to match recommendations as well.
Has anyone even remotely had the same issues that we are experiencing?
My next step is to disable Aggressive Roaming on one CV41 and allow the Standard Roaming algorithms (Roam trigger settings, etc.) to take over.
Coverage is not an issue and kudos to Ruckus on that end. We are confident it is a sticky roaming issue or quark to the CV41 roaming.
Thank you all.
