Frequent disconnection of network in laptop?
Since you've already tried replacing the network card, there are only three other likely causes.





1. Bad wiring to the switch port. Try a different patch cable. Also, try connecting through a different network port in the office. The 568B wiring standard is very specific. Split pairs or excessive untwist on punchdown strips or cable ends will severely degrade or block network activity.





2. Bad switch port. Try connecting to a different switch port. Repair or replace the switch, as appropriate.





3. Wire distance to the switch port exceeds 100 meters (328 feet). This is an exact limit. Exceeding it even by a few inches will start to degrade network performance.
