Network port going off frequently

Hi,

I've bought a new assembled system few weeks ago. I've been facing a serious issue from the second week onwards.

I see that the local are connection of my system getting disconnected very frequently. It goes disconnected and then after few seconds, it connects back. But after sometime, i could see that it gets disconnected permenantly and the lights are off at the network card. Then i had to restart the system to get this connected again, but the same thing happens again after sometime.

Following is my system specification:
Intel® Core™2 Duo Desktop Processor E7500
Intel® Desktop Board DG41TY
Transcend 1GB DDR2, 700MHz
Segate 1TB HDD
Windows XP Professional with SP3

Diagnosing done so far:
Virus scan using Symantec End Point Protection with the latest updates
Virus scan using McAfee with the latest updates
&No virus found
Re-installing OS

Please do let me know if you have any updates i this issue.

Thanks

Hi,

I just did the following and then it went off. Thanks for your support.

Goto Device Manager > Network adapters > Right-Click the 'Realtek' controller > select 'Properties' > select 'Advanced' tab and locate the option called "Link Speed". Change from "Auto-negotiation" to another option such as '1000Mbps', '100Mbps' or '10Mbps'.

Thanks
