Recently, my area had a wind storm, and I lost power for nearly a week. The power is back on now and it seems my computer is not able to browse the web (tried IE and FF3), although I am able to IM through MSN, AIM, Yahoo!, etc. and play online games such as WoW. My computer was perfectly fine before the power went out. My computer is connected to a Wireless network in the same room through a Netgear router connected to an Insight Broadband cable modem. I am pretty sure this is a problem with just my computer as I am able to browse the internet (and ask this question) on my parents computer and my mom's laptop, which all connect to the same router. I have found that I am also able to ping any website. Also, I am not able to system restore. This has been very troublesome for me for the past week since my power has been back on and I would love to fix it as soon as possible, as it is very inconvenient having to use my parents computer. Thanks to anybody who is willing/able to help!
My computer Microsoft Windows XP Professional
Service Pack 3
Also, if you need any more information, please ask!
I had the same sort of problem tried alot of things said and nothing worked untill I looked at the connection settings for IE and the LAN settings had the use proxy box ticked and that was the problem so on IE try :
Tools > Internet Options > Connections > LAN Settings
1) Turn Off your windows firewall to see if the firewall setting have been changed and then try to surf without any firewall settings. Remember to turn off all firewalls, such as norton mcafee zonealarm etc.
2) Check to see if your web browser has a proxy setup.
A high percentage of connection issues that occur when you have an internet connection but can't get a browser to hook in is due to firewalls. If your browser won't connect, first try disabling any firewall (you should never have more than one firewall on your computer) and then check for ability to get browser to hook up. If that doesn't work, then remove your firewall from your computer. If it won't uninstall, then remove it manually. Directions on manual removal of firewalls are available on the internet. I recommend addressing the firewall issue first before examining other possibilities.
My Firefox has used the proxy system settings. I don't know why this was set up that way. I have changed it to no proxy and now it works. But I cannot call IE to change the proxy settings. IE wasn't working anymore. The reason was a access problem for file C:\Users\...\AppData\Local\Microsoft\Windows\WebCache\V01.log. I have renamed the file and at the same time a new file V01.log was created and IE is working again.
