I have a 1 yr old Dell Inspiron 530s from a client. They never opened the box and let the computer sit for the past year. So, it is essentially brand new. The OS is Vista Home Prem. x64. Upon setting up the unit (and I've set up hundreds of new computers), it intermittently loses it's network connectivity.
I have it connected to a Motorola Surfboard cable modem w/ Comcast as the ISP. Other systems, which I hook up to this connection, have zero issue.
I've run a ping test with the (-t) switch... it will show about 4 to 5 replies each w/ a normal speed of somewhere between 11 & 50 ms. Then, it will stall & either tell me that it cannot find the host or the ping location. Or, will show a reply but the speed will be 2000 to 3000 ms.
I've tried disabling the onboard NIC & installing a 10/100 NIC (w/ x64 capability)... exact same issue. I then moved the secondary NIC to a different ISO slot... same issue.
I have now purchased an Intellinet USB 2.0 adapter. EXACT same issue.
I'm guessing, at this point, that it is an issue with the motherboard.
Has anyone EVER seen something like this? Is this a known issue with Vista Home Premium, or with Vista x64 environments?
