Internet connection

[Guest]

Windows XP Home, SP2, IE7
High speed cable connection with DHCP, no router

Everything is working properly until I leave the PC untouched for several
hours, say overnight, then I cannot check my email or bring up web pages, and
I get a server not found message. When trying to repair the connection I get
the diagnostic below. I have also tried to reset the modem, has no effect.

Upon a reboot everything returns to normal.

The "Limited or no connectivity" error message indicates that your computer
is properly connected to your home network; however, the ISP's DHCP server is
not assigning it an IP address. This problem could be caused by a failed DHCP
server on the ISP's network, a failed modem, or a problem with your Internet
connection. Alternatively, the ISP may require you to use a "static" IP
address, which only its support staff can help you configure.

The ISP keeps stonewalling my complaints, no big surprise.

In case that there is some Windows setting which causes this, what could it
possibly be?

Try this:
Right click My Computer and select Properties from the drop down list. On
the System properties click Hardware tab then click Device Manager Button.
On the device Manager locate your Network Adapter and right Click it,
select Properties then on the Adapter properties click Power Management Tab.
Uncheck these boxes:
[ ] Allow the computer to turn OFF this device to save power
[ ] Allow this device to bring the computer out of standby you can
check this box if you want the Network state to be refreshed?.
[ ] Only allow management stations to bring the computer out of standby.

The same on the modem Power managent and uncheck or select allow the
computer....

Right click on the Desktop and select properties, on the Display Properties
click on Screen Saver then on Power button and sett power schemes for Never
under the Plugged In.
HTH.
Let us know.

Thank you, but the adapter properties' window does not have a Power Management
tab.

The monitor power management I had already dealt with.

I see no way to get, with software, to the modem.

USB Cable modem ? There's also power-management for USB ports as well.

The ISP keeps 'stonewalling' you because if a reboot fixes it, this is your
problem, not there's

Cable modem is not USB.

Do you have Zonealarm as a software firewall, if so add your internet adapter
to the trusted zone, also if you have a router/firewall add the loopback
adapter to the trusted zone, if they are not then DHCP doesn't get refreshed
and you lose your internet connection.

Hi,

This most likely looks like the DHCP server is unable to renew your IP
address lease.
Try this command in the command prompt window,
ipconfig /all
you must find an entry for Lease Obtained and Lease Expires. Check this
next time you loose connection.
Thank you
