I have a suspicion that this is what is happening. When the service was downgraded to a lower speed it continued to be a fraction of the rated speed. Normally, DSL should not do that. This implies that some bandwidth is being consumed by NACs. The speed measuring sites do not seem to register NACs. ************************************************************************ * ==> QUICK LIST-COMMAND REFERENCE - Put the following commands in <== * ==> the body of an email & send 'em to: [EMAIL PROTECTED] <== * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?
