I am using Windows Vista Ultimate SP2 32-bit. I have the same problem coming out of sleep mode as well, I wake the machine, the network icon on the taskbar changes to having the red X underneath it for 4-5 seconds, then it comes back up connected, but won't
show me the small world globe, indicating a connection to the internet. Of course if I open a browser, I have no internet connection, but I have local network connections, to my network storage drive and both of my network printers, and other local PC's on
my network.
The thing is, I use STATIC IP addressing on my networks and have for 15 years of building PC's, networks, and IT support. My settings in Vista are set in the IPv4 properties, with IP, Subnet, Gateway, and DNS fields populated. Also, with ANY machine I
build, be it XP, Vista, or Windows 7, I ALWAYS turn off the power save mode for the LAN adapters, under the device's own Power Management tab, as soon as the OS finishes installing.
So, I can't see Microsoft pointing to this as a DHCP problem, that's pretty assumptive to think that all users use DHCP, and my adapter should "see" all of it's static settings when the machine wakes up, and they are nowhere near the DHCP range of my router,
which I reserve 10 settings for wireless items and guest PC's in the .230-.239 range.
The only recourse is to reboot my machine, which sucks if I had walked away 2 hours earlier with some research pages open in my browser or a thread I was perusing after an exhaustive search. Those items are closed and lost on the reboot, and I have to start
all over again. I like to be able to use sleep/power save options to save energy, but the only recourse here is to NEVER let the machine sleep, wasting power and straining the PC by never letting it cool down.
We need better answers and better solutions Microsoft.
