For about a year now, I continue to experience an occassional intermittent yet consistent problem with the "Network Adaptor" for my Broadband Router. Please note this issue not only relates to my current Router but also relates to a previous Broadband Router, so I don't believe the issue is anything to do with my Service Provider or Broadband Router but I believe it is some issue in Windows Vista relating to Network Adapters.
Some days when booting up my PC, I have no internet connection (which is shown by a red cross through the 2 blue computer icons in my Taskbar) because no Network Adapter is present.
When I check Device Manager, no Network Adapters are present so I add randon legacy devices choosing from Intel or Microsoft (e.g. Microsoft Isatap Adaptor) plus pre-installed Adapters shown in the list. After doing this and rebooting or switching off completely and back on again, sometimes the PC will connect to the internet using NVIDIA nForce 10/100/1000 Mbps Networking Controller.
I could not connect this morning and 8 hours have passed today with me trying to resolve the issue again without success, however after shutting down the computer and leaving it off for an hour and re-starting, once the PC has settled down usually after 5 to 10 minutes, it connects again to the internet using the Network Adapter NVIDIA nForce 10/100/1000 Mbps Networking Controller.
I am not even sure if this is a Network Adapter.
Could anyone provide information on why I experience this internet connection issue frequently and what I can do to eradicate the connection issue completely and what details I should check for LAN settings please.
Thanks very much.
