Random login problems
Network Manager sometimes seems randomly to require login even though that has already been entered before. This is usually due to a bug, but it has an easy solution:
- Right-click the network icon in the Notification Area > Edit Connections …,
- On the screen that pops up highlight your network access point and click the Edit button on the right.
- On the next screen click on the General tab and check the box for “All users may connect to this network.”
