Kinan555,

Without knowing which Latitude you have, what Operating System and Service Pack is installed on it, and which network adapter is in use, it's not possible to offer specific advice. Check in the Device Manager and see if the adapter is flagged as having any problems. If there's a diagnostic available for the adapter, run it and see what it reports.

The "voltage problem" message is worrisome. If the system is under warranty, contact Dell Support for assistance.

Hi Jim,

It is Latitude D505, OS WINXP SP2

Network Adapter type: Intel PRO/100 VE Network Connection

I checked device manager and everything seems to be ok and normal, also I checked Intel PROSet program which comes with the adapter and it shows that everything is normal except that the cable is unplugged

Best regards,

Kinan

 

Kinan,

In case it's the cable, or the connection on the other end of the cable from the laptop, can you try another cable, and try using a different connector on your router if one's availble? Also see if wiggling the cable around gently makes a better connection.

Jim

I once had a similar problem with a ThinkPad.  It had a bent pin in the LAN jack on the PC.  You couldn't easily tell,  but once I used a small pin to lift it back up,  the problem went away and that system and it is still working great today.

Kinan,

Unfortunately, that sounds right. You've checked all that can be checked. If the system isn't under warranty, you might consider purchasing a "PC-Card" network adapter and just disabling the internal one.

Jim

Have you turned off the option which allows Windows to shut down the NIC to save energy. It sounds like your NIC was removed (logically) from power before it dropped the connection.

No I didn't,

Could you please clarify
