--- Comment #7 from Neil Rickert <nwr10cst-os...@yahoo.com> --- >Could you please check whether this is not a duplicate of bug 378554? Yes, it appears to be the same bug. I set "allow auto-negotiation". Then "Apply" was no longer grayed out. I changed the MTU to 1471 and clicked "Apply" (and was prompted for root password). Checking the connection file in "/etc/NetworkManager/system-connection", the MTU information had changed to 1471. I was then prompted for the "kdewallet" key. I'm not sure what that is about, since this is a wired connection. I closed the connection editor. Then I restarted it. I could see that "allow auto-negotiation" was still checked. I changed the MTU back to 1472. And that caused "Apply" to no longer be grayed out. And I was able to save those changes. -- You are receiving this mail because: You are watching all bug changes.
