XP loses ethernet connection

Fresh install of XP w/sp2. With MS rcommended updates.
On board ethernet adaptor. (Broadcom)
Installed drivers for ethernet adaptor. Network works, access to internet
is fast with no problems.
But...
Everytime I restart the computer XP loses the connection. It's shown in
"network connections", but no connectivity. In "Device Manager" the proper
adaptor is shown and says it's working properly. If I unistall the adaptor,
then run "new hardware", XP finds the correct adaptor and installs it.
Connection is then good until I have to restart the computer.
I'm building a new computer, so lots of restarting!
How come XP keeps losing it and how do I fix it?
 
Hi,

Do you have a router assigning a DHCP IP to your PC? In network connections
can you right click / properties the connection and select "Repair". Does
that work?

The FREE Web page utility you always wanted.
Keep your router connected.
Email your IP to where you need it.
Test your enterprise Web Servers.
Plus lots more!
 
Network connection repair does not work. Says: Can't find IP.
Yes the computer is hardwired through a router. My laptop running XP doesn't
have this problem. (others are running WIN 98 and no problem)
 
Hi,

This sure sounds like a local ethernet cable problem. Can you change the
cable?
The TCP/IP settings for the adapter are set to "Obtain an IP address
automatically", yes?

In device manager you could right click the Broadcom and uninstall it. Then
re-boot to cause a re-install.
That might shake it loose? I guess you have the latest driver?

I'm running out of ideas.

Good luck,

Something else to try:
In the Device Manager, double click on your ethernet adapter and select
the "Advanced" tab on the next window. One of the advanced settings is
"Speed and Duplex" which is usually set to "auto". Sometimes the card
is not very good at auto-detecting the correct speed and duplex. Try
forcing this setting manually and see if it helps. Usually Half-Duplex
is used for Hubs, while Full Duplex is used for just about any other
device including most Routers. You might also try going to the Power
Management tab and uncheck the "allow the computer to turn off this
device to save power" (although I doubt this is your problem).

Good Luck,
John
 
Thank you both. Tried all suggestions (speed, no power off, uninstall,
etc.) Sometimes the connection works right after boot-up, sometimes I have
to uninstall and reinstall the adaptor to get it to work. Then it it works
fine 'til I have to reboot. I am going to double check drivers. Didn't try
cables, because it works.
Thanks again for the help.
 
Umm,

"Didn't try the cables because it works." ? If it works then it is
fixed!! :-) If you are still having troubles TRY a new cable.

As an Apollo 12 astronaut said after they were hit by lightning and the
command module power totally failed just after launch - "I guess we had
better try the override switch". Nothing else works.. it worked & saved
their lives.... ;-)

Works in the sense that when adaptor is reinstalled it has no trouble getting
an IP!
When I'm rebooting, I'm not unplugging and plugging in the cables.
But what the heck, cables are easy to switch.

You say that you installed the drivers for your Ethernet NIC... Did you
get the latest drivers from Broadcom:

<http://www.broadcom.com/support/ethernet_nic/downloaddrivers.php>

or did you use the drivers supplied by your computer/mb manufacturer?

Whichever you did, you might want to try the other.

HTH,
