I want to post a problem that we are having here. We have a Psion G2 Scanner as wireless endpoint and WLC with ACS authentication. We an issue of speed of the transaction carried out by the application in the Psion Scanner which takes around 12-14 sec, which usually occurs around 1-2 secs. We had tested tracert from the scanner to the application server itself and it seems to be in the region of milliseconds.
Also the SSID is not broadcasted and uses WPA. One thing is that when using the DHCP its slow but when the same DHCP acquired address is statically configured then it is fast. Is it anything to do with the DHCP snooping in the WLC or anything else?
If anyone can throw their thoughts in this, its highly appreciated.
