Starting about 10 days ago, my cable internet signal to my desktop drops every night forcing a reboot each morning to restore internet access. With desktop signal out, ran cable to laptop and all worked, thus ruling out modem or router problem. Only thing I can think of that has changed is recent XP security update from Microsoft. Am also running Zone Alarm and AVG. Any ideas what is causing the signal to drop every night? This has me stumped.

An internet signal dropping out causes a reboot? I doubt it. Have to prevented XP from rebooting on a serious error? To have XP display the error message instead of rebooting: 1. Click Start, and then right-click My Computer. 2. Click Properties. 3. Click the Advanced tab, and then click Settings under Startup and Recovery. 4. Under System failure, click to clear the Automatically restart check box. 5. Click OK, and then click OK. Sorry, I do not check for private messages

Sorry, my message wasn't clear. To restore internet access, I manually reboot the machine in the morning. Everything is on and working fine when I first go to the machine. I just can't access the internet until I manually reboot. Some process during the night is causing the signal to drop.

1. If you want to chance it remove the security update. 2. Change the computers clock when you start working to midnite. Keep the computer on for six hours. Check every hour to see if you still have internet access. 3. And of course call your provider. My cable box warns me at 1:15AM that it will turn itself off unless I press a button on my remote.

I think it was something in the security update for ie6. I took a chance and replaced ie6 with the beta of ie7. Yesterday and this morning my signal was still good! Hopefully, this has solved it.
