I changed my ad settings yesterday on my Samsung Galaxy S6 I opted out of all ads and suddenly the proxy server settings stopped working. I have no idea where to begin to repair it.

Hey Terri, I have two options for you to try: Option 1 Did you try factory reset yet? If not: -Open the Settings menu. -Go to ‘User and Backup’. -Tap on the ‘Backup and Reset’ section. -Press ‘Factory data reset’. -Confirm that you wish to Factory Reset your smartphone. -Enter the alternative password for your device. -This will erase your phone(music, apps, etc.) -This also confirms whether this is a software or hardware issue. Option 2 Go to settings and click on Wi-Fi. Then chose the network you want to connect to. Press it down for about 2 seconds and a window will pop up. Choose Modify Network. Scroll down to show advanced options. Click on it.Under proxy settings click on none and click save. -Let me know how it goes. -Please accept this answer if it answers your question.
