Hi Guys, I'm currently using 2 systems right now. One running on Windows Vista and one on Windows 7. A couple of weeks back, my connection started getting extremely slow and at times, i kept getting error messages indicating that the page could not be displayed and such. This carried on for about a week until I had to perform a system restore on both to get Internet access back on them. Now, a week on from the system restore, the same problem has started to happen and I've already lost my internet access on my Vista once more. This is entirely frustrating and I cannot seem to pin-point the problem to a specific cause. I've tried running a full scan using Kaspersky - nothing found. Here are some details: - Windows Vista & 7 - Kaspersky scan - none of the usual suspects come up - When I called my cable operator, they told me to plug in my PC straight into the router, which I did. They then asked me for my IP address and when I told them what I had, they told me it was an invalid IP address and told me it was probably an error with my machine. - Other machines on my network run fine with fast and efficient internet access. It's only these 2 machines that I use that have this problem. - When internet connection went out, I tried going into CMD and tried to ping a few websites and IP addresses. Only reply came from the IP address of my router. PLEASE HELP!!! I REALLY REALLY need this problem resolved! I can't seem to find a solution anywhere online. I tried following steps for DNS probs and the works, but nothing seems to fit right in rectifying this error! I appreciate all help, advice or redirection to another thread if it may assist in this issue. Thanks!
