My computer LAN connection says no connectivity. Get a DNS error. How can I fix this?

Question

My computer worked fine last night. Came in this morning and I couldn't bring up the internet. All lights on my DSL box and wireless router are on. I can't access my wireless on my laptop, though, either. I switched my laptop over to the main computer and the LAN works fine.

The computer gives me this error when I access the internet:

res://ieframe.dll/dnserror.htm#

Connection status says: "This problem occurred because the network did not assign a network address to the computer."

When I go to repair, it says: It cannot renew my IP address.

Network connection details shows no addresses after the term DNS Server.

After running a Windows Diagnostics for Windows XP, it shows it cannot connect to anything; microsoft.com, passport.net, ftp.microsoft.com; and that it cannot make an HTTP, HTTPs, and FTP connection.

Can anyone please help? Or is my computer toast?

Thanks in advance!

Answer 1

no its not your computer, shut down computer and router then reset router by pressing the little button for 30 seconds then restart all, go to network connections and or browser, tools, internet connection and make it "automatically" search for connections.

hope this helps

Answer 2

Your laptop is not toast, but your wireless adapter is suspect.

Try deleting the existing network connection and creating a new one.  Make sure you have the SSID name and the encryption key for the WPA/WPA2 security so that you can authenticate to the wireless router from your new connection.
