Psion Workabout Pro connectivity issue with IBM iSeries AS400

unknown

We are using Motorola Psion Workabout Pro 3 & 4 devices and since changing our WLAN infrastructure to Ruckus our devices experience a delay with communicating to our IBM iSeries AS400 system. Has anyone experienced this same issue?

I see you have opened a ticket with Vivek, who suggested 9.8.2.0.15 firmware


upgrade. Scanners using an AS400 server system, like VoIP or telnet based


applications, are very time sensitive, and do not work well with dropped packets.



We typically advise using WPA2-PSK (AES, not auto), high priority on the WLAN,


use a dedicated VLAN, and perhaps tunnel the WLAN traffic if the AS400 is


located with your ZoneDirector. You will need to find clean air/low interference


channels. 5G has typically less interference, if the scanners can use 5G. Else


analyze the AP support info files to determine if the AP sees a lot of interference,


(Histogram under Athstats), or the scanner client is perhaps near to a source of


interference on the floor (reported as PER in client stats).
