Hello, we have Datalogic X3 and X3+ devices. Devices with Windows Mobile works good. But devices with windows CE 6.0 works much slower.
Ping latency to connecting host are almost the same from both devices.
NTLM authentification helps a bit, but not much.
People on this thread wrote that Wifi drivers update helped.
We ask the PDT vendor to update the wifi driver. Combine with using the “Use NTLM Authentication” = TRUE, the client is quite satisfy with the performance.
