I had this problem all the time on both my computers. I was using Norton systemworks, so I installed registry mechanic, and the same thing happened. I uninstalled completely all traces of both programs, and downloaded AVG free edition anti-virus, have had absolutely no problems since. Don't know what anti-virus you are using, but this might help. One computer has windows XP home, and the other it the pro version. Good luck.

That is my problem with DSL too! Sometimes I cannot connect to the internet after standby, and it works after restart. It is more offen when DSL connected to PCI USB Card - not motherboard USB...

I agree that your problem is caused by either BIOS or driver settings. However I daubt that updating these will solve your problem. As is normally the case the "updater" will simply copy your previous settings.
I would advise you to look at your driver/BIOS settings. Don't be afraid because if you mess something up just undo it later. A wrong network / power management setting can't just wipe your HD clean ;-).
You might even learn something in the process other then with a wishfull update.
How To?
Drivers: Configuration Settings -> System -> HardWare -> Device Management... Select your network device and right click -> settings ... -> Power Management
BIOS: press delete(default) button before windows loads and go to the power management section where you will find all sorts of interesting options.

unchecking "turn this device of to save power" in driver settings normally does the trick.

Hope i helped...

If you cannot connect to the internet after resuming from stand-by or hibernate mode, and you use Zone Labs security software, then that is the culprit. Just ask them; they'll tell you. Or uninstall your Zone Lab software, and see if the problem vanishes.

When troubleshooting another problem, the support desk for my router manufacturer told me to remove my LAN connection from "Network Bridge" I think the steps on my Windows XP PC were:

Start | Control Panel | Network Connections
Right click on "Local Area Connection" | Remove from bridge

I don't recall if other steps were required to reestablish the connection, but my "Local Area Connection" is now on "LAN or High-Speed Internet." This seemed to fix the problem of no network connection after waking up from sleep mode. I'm not sure why my Local Area Connection was in the "Network Bridge." My PC came that way from the local shop that custom built it for me.

I have a wired LAN connection to a router to a cable modem.

I fixed the same problem with my Windows MCE HTPC by checkmarking everything but the last box in the Power Management settings of my NIC card. This allowed Windows to turn the NIC on or off and I guess initialise it in the process.

I disabled my Ethernet connection and it worked. Now I remember that the problem started after I connected my laptop to Internet through the Ethernet connection

I have windows xp home edition on a toshiba portable. New update from microsoft puts me into standby when left idle. Cannot re-connect to internet without switching off. Help required (as simple as you can make it)
