- Then your PC is broken. The BNC connector is supposed to be completely
- electrically isolated from the system ground. Multiple grounding of a thinnet
- is a good way to up your error rate. Faulty interface cards are one way to
- cause this; T-pieces and barrel-connectors touching against random pieces of
- metalwork are another.
