Internet connection problem: "Windows could not automatically detect proxy settings"
Problem: I can't connect to the Internet on my laptop, a Dell Inspiron running Windows 7 Premium. The error message in IE reads "Windows could not automatically detect this network's proxy settings." This is a new, sudden problem this week after connecting before just fine.


My laptop "sees" the wireless network just fine, with a good signal strength. My other computers are using the same wireless networks without problems.


On the laptop, when I look at Wireless Network Connection Status (General tab), it says:

Connection
IPv4 Connectivity: Internet
IPv6 Connectivity: No network access
Media State: Enabled
SSID: berman [the network which my other computers are using just fine]


Things I've tried already:
-Reset Internet Explorer settings
-Rebooting in Safe Mode with Connections
-Disabling firewall/McAfee
-Making sure Proxy server is not checked in Local Area Network (LAN) settings in Internet Options

looks like you have a good connection to the router on the wireless
however, appears something maybe blocking access to the internet

What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, Mcafee , AVG etc

do a tcp/ip stack repair

------------------------------------------------------------------------

TCP/IP stack repair options for use with Vista/Windows 7

Start> Programs> Accessories> and right click on Command Prompt, select "Run as Administrator" to open a command prompt box
(A new dialogue box - black with white font, will appear on the screen ):

In the command prompt window that opens, type the following commands:

Note: Type only the text in bold and red for the following commands.

Reset WINSOCK entries to installation defaults: netsh winsock reset catalog and press enter

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log and press enter

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log and press enter

ReStart (reboot) the machine.

If you receive the message
The requested operation requires elevation.
Then please open the command prompt as administrator - as requested above
Start> Programs> Accessories> and right click on Command Prompt, select "Run as Administrator" to open a command prompt box
(A new dialogue box - black with white font, will appear on screen ):

Please note and post back - if you receive the following message :-
Access is Denied

please post back the results in a reply here - its important we know that these commands have worked correctly and not produced any errors
right click in the command prompt box
select all
enter
control key + C key - to copy
then reply here and
control key + V to paste

Software: The laptop has had PC Cleaner PRO, McAfee antivirus; I disabled the former and uninstalled the latter. I've run a virus check with Windows Defender and McAfee (before uninstalling it.)

I did the above process, with the following output:

C:\windows\system32>netsh winsock reset catalog
Sucessfully reset the Winsock Catalog.
You must restart the computer in order to complete the reset.

C:\windows\system32>netsh int ipv4 reset reset.log
Reseting Interface, OK!
Restart the computer to complete this action.

C:\windows\system32>netsh int ipv6 reset reset.log
There's no user specified settings to be reset.

...and then I restarted the computer. The error message re: proxy settings is still present, with no other obvious changes in connectivity.

What next?

Thanks!

Control Panel - Internet Options - Connections tab - LAN Settings. What choice(s) selected on that page? Unless you are using a proxy try with none of the three choices selected.
