Cisco 1231 APs and Intermec CK31 clients

[PULSAR]

Hi all,

we have a big warehouse covered by some APs, standalone 1231G. Channel distribution is ok, we use just 3 channes (1, 6 and 11, European domain). A site survey reveals that there are no interferences and that we cover all the area with enough S/N ratio.

We use LEAP and a ACS server for Radius authentication, also WEP for encryption.

The APs have a vlan for management. The WiFi Intermec clients belongs to a different VLAN, therefore the SSID is associated with that VLAN. The APs are connected to a Cisco 3560 PoE switch.

The problem arises when randomly several times aday, the Intermec seems to be "hang" when reading a Code (this device is a "long" distance bar code reader)... the Intermec uses TN2000 to connect via WiFi to a AS400 where the code readed is introduced. Sometimes after 2 or 3 minutes, the code is introduced and the devices comes to life by itself...other times we need to ESC and F3 on the device to recover normal operation. During the time that the devices seems "hang" I still can ping it...

Can somebody help me with this? I suspect of a problem on the Intermec device.

many thanks

pulsar.
