Here's a new one I have never seen. I am connected through an ethernet card to high speed cable internet. All the lights on the cable modem are lit properly. Once I start the computer, the internet connection is great. No problems at all - good speed and so forth. After a couple minutes the internet connection just stops. Internet Explorer, Outlook Express, AIM, FTP programs, nothing can do anything on the internet. To get the internet running again, I have to release and renew the IP through WINIPCFG, or reboot, or unplug the modem and plug back in. The lights never change on the modem. It appears to be working fine. Does anyone have any ideas what would cause the computer to stop internet access like this. I am on Windows XP Pro, 1.7 P4 with 512 Ram. It worked fine until the other day (and I had not installed any programs). I even went back to a ghost image I had made and the same issues. I use Zone Alarm Pro but never had any probelms with cable access before. I have used the same cable providor for 4 months with no issues until the other day. I also uninstalled and reinstalled Zonealarm Pro just in case in got corrupted. No luck. Any help would be greatly appreciated !!! Thanks in advance.
