Windows could not automatically detect this network's proxy settings

Recently, I have noticed a small caution triangle appearing with my network icon on the task bar. When I right click and troubleshoot, it comes with this message. Windows could not automatically detect this network's proxy settings. My internet has been very slow lately, but I'm wondering if this is a problem with my network? or is this something that my ISP has to fix?

(This post is intended for all reporting the problem)

Check Internet Options (from Control Panel or Internet Explorer Tools / Options  /Connections Tab / LAN Settings and make sure Proxy Server is unchecked even if using Firefox.  Check settings in Firefox in Tools / Options /Advanced Connections / Settings  (should be either use system proxy settings or no proxy).

Check for malware especially using malwarebytes.

Try  these two commands in that order in an elevated command prompt.  Do the first one first then reboot and try.  If still bad try the second.

netsh winsock reset

netsh int ipv4 reset

If these don't help, please post the output of an ipconfig /all command

I had the same problem this morning--couldn't connect on one computer but could on the other.  Got the same message about not being able to detect the proxy settings.  However, I used System Restore to reverse some changes that had happened during the night and that corrected the problem.

    Still running with no issues and no more error messages.  The troubleshooter now asks me if I'm looking for help with another issue since it can't find any on its own.  I say give WhiteMamba's solution a try and revert back if things don't work correctly.

    I have my Sony Vaio laptop with me on a business trip to Mumbai, and both my wireless and wired connections simultaneously stopped working 2 days ago after working perfectly for the first week. Wireless can "see" lots of networks, but can't negotiate a connection. Wired doesn't even see the presence of a signal. I assume it isn't hardware because they are different adapters. I've tried EVERYTHING. System restores, disable/enable, etc. etc. I even called Sony tech support who were unbelievably clueless. I would love any suggestions, because I still have two more weeks on the road, and it's painful when the only connectivity is via my phone. (Oh, tethering no longer works either.)

    Thanks in advance for any ideas.
