I'm having a problem. orangepipc2 connects over wifi and cable but it does not surf and does not update. NetworkManager is locked for editing. Using the nm-connection-editor command as sudo I can edit. But it does not connect. I have edited the sudoers file. I changed dns to 8.8.8.8 without result. I modified several things on the router without success. ping command works on any site. If I use the smartphone hotspot it works very well.
sorry googletranslation.
