Solution
Since the PXIe‑8862 controller is running LabVIEW Real-Time (Linux RT), the use of wireless LAN is not recommended. Wireless connectivity on RT systems is not officially supported and may result in unstable network communication, potentially leading to unintended or unpredictable system behavior.
To ensure reliable and stable performance, it is strongly recommended to use a wired Ethernet (LAN) connection instead of wireless LAN. As a result, there are currently no NI-recommended or verified wireless LAN adapters for use with Linux RT systems.
