I recently purchased a new HP Pavilion Elite e9105z CTO Desktop and migrated from Win XP to Vista Home Premium x64, with a NVIDIA nForce 10/100 Mbps Ethernet Controller. Whenever I come out of sleep- or standby-mode, I lose my Internet connection and have to either reboot my system or run the Windows Network Diagnostics to repair the network adapter settings.
I have tried several remedies available from the Internet; but unfortunately, nothing has resulted in a permanent solution. I contacted my ISP provider (Mediacom) to ask if there was/is an issue with the firmware used to support my SBV5220 cable modem (e.g., non-compatibility with Vista) and they said there isn't. To date, I've:
- Reinstalled network card driver.
- Checked and reset power options with USB CDC.
- Applied update for Windows Vista (Default Gateway Setting is Lost ) for x64-based Systems (KB933872)--received response that update does not apply to system.
- Reset IP configuration via Cmd line.
- Under the Power Management tab, unchecked the box that turns off the adapter when power saving kicks in.
I access the computer several times a day and having to reset Internet connections has become extremely aggravating. I hope there is a solution. Thank you in advance for your assistance.
