Fix browser connection problems (^-^)

1: Check your connection

Press [Windows] + [R], type “cmd” and press [Enter]. Type  ping 202.188.1.5,ping 202.188.1.5 –t or
ping 202.188.1.5 –t –n 30 and press [Enter] – if you get a response, the problem is browser-related.

2: Try another browser

If you use Vista or XP, consider rolling back to Internet Explorer 7, or install an alternative such as Google Chrome or Firefox and see if they’re able to connect. This will help you to determine if the problem lies solely with Internet Explorer 8.

3: Is it universal?

If your connection problems are only with certain security websites or Microsoft Update, a malware infection is the likely cause. Turn to page 68 of PCA212 for a complete disinfectant guide.

4: Try Safe Mode

Click Start > All Programs > Accessories > System Tools > Internet Explorer (No Add-ons). If you can now connect, check out PCA215’s Helpdesk column on page 30 for a guide to disabling troublesome add-ons.

5: Verify settings

Select Tools > Internet Options > Connections tab. Check that the correct connection is being used – nothing should be listed if you’re connecting through your home network router. Instead, click “LAN Settings” and make sure only “Automatically detect settings” is ticked.

6: Check security software

Temporarily disable your firewall and anti-virus software to see if either of these are blocking the internet connection. If they are, look for an update or workaround, or replace the software with working alternatives.

7: Reset your browser settings

 Switch to the Advanced tab and click “Reset” to see if that fixes
the connection problems.

8: Flush the DNS cache

 Open cmd.exe again, as you did in the first tip, but this time type “ipconfig /flushdns” and press [Enter]. Then restart your PC.

9: Reset the WinSock settings

If you’re able to get online, browse to http://support.microsoft.com/kb/299357 for full details of how to reset the Internet Protocol (TCP/IP) using the NetShell utility. There’s also an automated fix-it tool. Otherwise, open cmd.exe, then type “netsh int ip reset resetlog.txt” and press [Enter].

10: Use System Restore

If the problems began after installing a recent raft of updates, use System Restore to roll back to before those updates were installed, then install each update one at a time. If your connection is then lost, you can concentrate your troubleshooting on this update’s KB number.
