Slow windows CE performance with NTLM Authentification

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.

"Hi,
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.

Thanks"

Hello, can you please open a ticket with tech support and specify the specific device model along with the firmware version? They will then follow up with you on your case more specifically. Thanks.
