verify you are spyware free
also, if it is a laptop, some laptops have a power-saver that runs on the NIC...which can cause the connection to drop or slow down.  for example, many dell laptops have this feature on their wireless NICs.  you can adjust the settings to turn the feature off.

Firstly are you certain its the NIC ?

Have you checked the cable - 75% of all network connection issues are down to faulty cable!

Is the hub/switch/router/dhcp box running ok.  It has been known for faulty Hubs/Switches/Routers to automatically power cycle every few minutes / hours which drops the connection.

good suggestions! You should also check for malware, virus, search toolbars (like YAHOO toolbar) can cause slowness.. was there anything installed recently?

Try to download and update an anti-spyware scanner:

Ad-Aware Personal

To check if you have any spyware
Please download HijackThis 1.99.1

Open Hijackthis, click  scan and save a logfile
then navigate to programfiles hijackthis folder and copy out the log file

Thank you for all your responses, the problem ended up being the Network card Model. After doing more research I found an article on MS that said to get the latest update from Microsoft to fix the problem. The nic card was a
Intel Pro 100. After the update everything continued working fine.

I split up the point because they were all good suggestions
