I'm using WiFi connections or a 3G modem to connect to the Internet, but sometimes the connections break and the LAN settings change to use a proxy server. I have never set a proxy server, and I do not want one.

I set it to Automatically detect settings:

But they somehow get changed back to using a proxy server, without my permission:

enter image description here

Notice the "some settings are managed by your system administrator" banner. Here are the advanced settings : where i have reset and restore them all :

Advanced settings that i set to default

I have tried rebooting, and other solutions on the Internet:

  1. I have deleted HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU to leave only the "default" entry.
  2. I have tried other solutions from Microsoft forums

How can I keep my network settings as they should be?

UPDATE 1 Here is a screenshot when clicking on advanced : Advanced settings

  • @DanielB i have added a capture but i have also restore and reset those settings , ans the problem still persist – The Beast Jan 27 '16 at 9:33
  • Hm, somehow my comment disappeared. Whatever. That wasn’t what I’m referring to. On the proxy settings dialog (“Local Area Network (LAN) Settings”), click the “Advanced” button when the “Use a proxy server for your LAN” checkbox is checked. – Daniel B Jan 27 '16 at 11:47
  • @DanielB yes ok and after that what i should do ? – The Beast Mar 6 '16 at 13:05
  • Provide a screenshot. :D – Daniel B Mar 6 '16 at 15:17
  • @DanielB ok i have added one but i have changed to automatically detect settings when i have boot up my laptop so they can be different ... but the settings as usual will switch back to proxy mode ... then i will verify if the settings stayed the same – The Beast Mar 6 '16 at 16:33

As you chose 'Automatically Detect Settings', it does just that, and the dedicated connection point in the LAN has a script ready that will run. As soon as you save, that script probably changes the setting to something different - in your case to 'use a proxy server'.

If you choose none of the check boxes, it will not ask for that script or execute it (but then your LAN might not work...)

I have the same issue whenever I connect from outside the company network, because the company network sets the setting (stupidly) to use a specific script (instead of leaving it on automatic), and the server this script is located on is not reachable from outside the company network. So I have to remove that setting manually every time I want to connect from outside.

  • I don’t see any relation to the question...? His question is about the settings reverting after saving. – Daniel B Jan 24 '16 at 20:46
  • I marked the part in italics. – Aganju Jan 24 '16 at 22:38

    That’s simply not true. The PAC script is run every time, because it can direct you to a new proxy on each connection. It can do more than the static options. – Daniel B Jan 25 '16 at 7:15
  • @Aganju it must be something we can do !!! this issue really disturb me – The Beast Jan 27 '16 at 10:38
