Periodic Limited Connectivity

[Adrian339]

Hi,

I am running Windows Vista, and every so often, in intervals that can be anywhere from hours to minutes apart, my (wired) internet connection will seemingly just stop/cut out, telling me each time that it has limited or no connectivity. Each time to fix it the diagnose/repair tool 'resets the network adaptor,' after which it works fine, untill the next random time it dies. As a quicker option I have recently been disabling / re enabling the Local Area Connection network device, which also temporarily resolves the problem. I am in a residence and nobody else is experiencing this problem.

I have no idea what is causing this, and am hoping that somebody knows more than I do and could possibly help me out. Many thanks in advance.

My ipconfig /all readout is the same for both when experiencing normal connection and when it is limited:

Try booting in Safe Mode with Networking and running long enough to see if it happens that way. If not, then it's something running in normal mode, we'll see if we can track it down.

Unfortunately it did occur during safe mode =/

That starts to look like the router, the cable, or the NIC driver or NIC hardware. Have you tried a new cable, a new port on the router, updating the NIC drivers?
