I'm sorry, anyone who uses 3com nics get what they deserve. Throw the @(#*$ 3com card away and get another (any other) nic. :) Even a $10 realtec would be preferrable. Athough the nic of choice seems to be the Intel Pro 100, and I can't say I've had any problems with them. I've just had my fill of problems with 3coms. I'm assuming you have tried another 3c905? I know for a fact that 3com believes in customer testing of their products. I have a friend who worked for a company who was acquired by 3com. He was one of the people who did test and rework. Basically, every unit would be powered on and would be run through a minimal set of tests to at least verify it functioned. 3com management was pissed off that they were failing too many of the units (or better put, they were catching too many problems before they sent them to the customer) and told them that if they weren't able to improve their post-test yeild they would have to just ship the products without doing the electrical testing.
