RSLinx ethernet IP driver with Red Mark in Allen Bradley Posted 14 Nov 2015 Hi everybody, Guess that the forum is useful because of the information and experiences exchange. So, i've found that there was a windows 7 feature enabled the same day RSLinx EthernetIP Driver stopped working. The feature is Microsoft Virtual WiFi Miniport Adapter. It's curious because i rememeber working in other PCs that had this same utility enabled and don't remember to have troubles with RSLinx Drivers. I just follow some steps to disable de WiFi Miniport Adapter, and after that, the Ethernet IP drivers in RSLinx worked properly. Now, i'm thinking... why the WiFi Miniport caused malfunctions in RSLinx Drivers, for a "fix it and move on" solution, disabling de Miniport is ok. but i think it would be ok if i could understand the reasons of drivers failure.
