You must use only 50ohm coax with a terminater at each end, and no stubs longer than 5cm (most of which is used by the card). Those BNC-to-RJ11 converters are for an obsolete IBM cabling system, not for Ethernet. Twisted pair is now so much better than coax that I recommend forgetting about ever setting up a coax network, and any that still exist should be replaced at the first failure. You should buy a well-marked Cat-5 cross-over cable for your system if your network cards support 10baseT. If you have a choice, buy either a yellow cable with molded grey ends, or red cables.
