We have a Psion Teklogix Wifi installed in our warehouse. It consists of a 9150 controller and several 9150T Access Points, each with two antennas. We use Tess 5250 emulator on the 7535 handheld. The problem is that we very seldom can log in to the iSeries from the handheld. It works maybe 5% of the time and we don't know why. Can anyone help us?
