I have a laptop with a wireless card and a lan card, when I disabled the wireless card the OPC-UA Server says Faulted, here is a pic of the problem. Why I need to have the wireless card active? ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/0/064348ec269a1699e275a4f5a9b069fc60fa4c4a.jpg) ---

Because the first time you started Ignition the OPC-UA server chose that interface to bind to. Go to the OPC-UA settings page and set the “Endpoint Address” setting to the IP address of your wired ethernet adapter (or try localhost if you don’t have an IP address assigned) and then restart the UA module. You’re going to consistently have problems with the UA connection if your IP address is not stable. ---
