test of Network adapter

[Crios]

I have a Fujitsu Siemens Amilo Pro V 3515 (157) Laptop
How can I test if my Network adapter is working properly ?
I want to do this because sometimes the transfer rate goes to zero, but it
becomes normal after I reboot.
The LAN is an office LAN with a permanent and almost constant internet
connection.

Thanx
Crios
