We have two 4/110's, and both were originally shipped with defective thicknet sockets. The symptom was that the connector was very sensitive to even slight movements; you had to fiddle with it to get it working, and then hope no one moved the cpu or cable. In both cases I shut down the cpu and connected an ohmmeter between pins 1 and 13 (the power supply lines for the tranceiver) and noticed that the resistance alternated between infinity and around 900 ohms when I flexed some paperclip probes inserted into it. I swapped one cpu board for a new one and found the connection to be much more reliable. The connection was maintained even when the plug was at a substantial angle to the connector. (I'm about to swap the other cpu) Has anyone else noticed this problem? Is it a design defect? Rich Winkel
