[QUOTE]\nSystem running 10base2, BNC interconnect. Computers are connected from \nthe nic to the wall via a single cable. NOT a T connector. Basically you \nare extending the center of the T connector in a normal simple \nconfiguration.\n[/QUOTE]\n\nIs this some kind of trick question? \n\nYou haven't specified the nature of the in-wall cabling. If the in wall cabling is 10base2 (thin net), then it\ndoesn't sound valid to me (but then again I'm not a network techie geek\n:-)) \n[QUOTE]\nHow long must the cable be from the wall to the computer???[/QUOTE]\n\nIf the in-wall cable is 10base2, then my answer to this is close to ZERO - \nthe center of the connector T should be connected as close to the NIC as\npossible for reliable operation.\n\nThe situation will be different if there are active devices in the wall\nsuch as a media converter (tranceiver) or repeater of some form - please\nclarify.
