Losing Internet connection after idle time...

I've had this annoying problem for quite some time now and I have been
unable to find anything online that would fix it...

I'm using Windows XP on a new (4 months old) Toshiba notebook computer. I
have a broadband Internet connection (satellite) that I'm running
through a server which allows me to share this connection with several
other computers in my house on the network. All of the other computers
can access the Internet just fine through this broadband connection and
none of them experience the problem encountered on this one notebook

I can boot up this notebook computer every morning and logon to the
Internet via my broadband connection on the network without any
problems at all. However, if this computer then sits idle for an hour
of so after logging on, when I come back to this computer and try to go
to another Web site, I get the standard message that the site is not
found indicating that I've lost the Internet connection. This happens
with any site I try.

But at the exact same time, I can switch over to another computer on my
desk (which is also using this same broadband Internet connection via
the network) and the same site I attempted to go to will come up just
fine on this other computer, telling me that there is no problem with my
broadband connection at the time.

However, I also have a backup dial-up account for this notebook
computer. After losing the Internet connection as described above, I
can switch over to my dial-up connection on this computer and
immediately logon and get right back online and go to whatever site I
was attempting just minutes before.

Then, after visting one or two other sites, if I disconnect from my
dial-up connection and go back to the broadband connection on this same
notebook computer, my broadband connection starts working fine again
and will remain so as long as the computer is not idle for more than an
hour or so.

Again, this only happens on this one computer on my network and it has
happened consistently now for several weeks.

For anyone who could suggest a solution to this problem, I would
greatly appreciate it.

A few questions....

1) What type of server device are you using? Router/PC with ICS or some proxy program?
2) Ehat type of NIC is being used in the laptop? Wireless onboard or plug in card, wired?

A few questions....reply

Thanks for reply.

1) I'm using a software proxy program on the computer that is acting as the server and this is connected to my satellite modem. The proxy software is WinProxy. I've been using this for a few years now and it has worked fine. Again, all of the other computers on the network do not exhibit this problem.

2) This is an Ethernet card that is built into the notebook (i.e., it came configured this way and I did not add it.

Hope this helps, and thanks again for any support you can provide on this problem.

Try device manager

Have u tried going into the device manager and in your network adapters,properties,power management and uncheck the box next to Allow the computer to turn off this device to save power. Maybe this will help.

Try device manager... This seems to do the trick!...

Thanks so much to andre3000 for this suggetion. I tried it, and so far this seems to have done the trick!

For anyone (like me) who needs some step-by-step instructions on how to do this, here are the ones I used on my XP system to get this done:

To open Device Manager, click the Start button.
Then slide up and click Control Panel
If not already in the Classic View, click this option
Double-click the System control panel icon
Click the Hardware tab, and then click the Device Manager tab
Click the '+' sign next to Network adapters to expand this option
Right-click on the icon for the Ethernet (NIC) card (e.g, Realtek RTL8139...) and select Properties
Click the tab for 'Power Management'
Uncheck the box for 'Allow the computer to turn off this device to save power'
Click OK and close out of all open windows.

Thanks again for the help...

Firewall Settings?

I would point out that some firewalls allow a period of inactivity to be set prior to dropping the connection to the internet. I believe this applies to the free edition of ZoneAlarm. Could this be the case here?
