Internet Connection Problems.

Coincidentally I have run into the same problem in the last few days and was about to start a thread on the subject I am running the retail version (from Technet) of Windows 7 Pro x64.

Generally happens when the computer is restarted or woken from standby/sleep.

I have 2 NIC's - occurs on both and have even gone to the extent of loading a week old image of the drive which seems not to have resolved the problem.

I shall follow this thread with interest!

 

Possible cause on multi-boot systems:

The router logs the net name of Windows comps. The name may be different on each operating system. Usually, routers don't log the net name when running Linux, unless Samba is loaded at boot. Routers can become "confused" because the mac address is the same for each operating system on the comp. Solution is to use static addresses.

I'm triple booting my desktop, XP Pro, Debian, Win 7 Pro Final, using dhcp, no issues with lost connections.. No file sharing on any op sys, only access to shares on other comps.

Thanks - I understand what you are saying re multiboot, but after sleep or a restart the XP install has not been connected to the Internet. Anyway, as XP is effectively redundant now apart from reference I'll kill the internet connection there and monitor the effect.

If Tony is right your router is the common link to the internet, regardless of which hard drive the OS in use is on.

 

Let us know what happens.
Also, realize that some Windows drivers for network adapters have built in support for power management, i.e. wake on lan, disconnect at hibernation, suspend, etc. Have a look at the driver properties via device manager.

Linux does not disconnect networking at logoff, suspend, etc. In fact, in linux, networking is initiated and completed prior to logon. That's because linux is a server based operating system. Services are initiated and loaded before a user actually logs on. And services remain loaded after logoff.

 

Right - killed the Internet connection on XP, back in 7 the problem is unchanged.

Have dug deeper and unchecked 'Allow the computer to turn off this device to save power' on both NIC's - only one in use.

Internet remained connected after a sleep period, but 'one swallow does not make a summer'

Found a lot of hits on Google relating to this problem with Vista, but no solutions.

 

Encouraging results to date - 5 or 6 Power Saving induced sleep periods today and so far the internet connection has not dropped out on wake

 

Great! That means the remote access trojan we put on your comp can now talk back to us 24/7. Now...if we could just get Pete's Webcam to stay on all the time...
