Ethernet auto-connect, auto-sense doesn't work
I have noticed that a common issue to several distros is the fact that the networking subsystem doesn't automatically detect the link if an ethernet connection is disconnected and then re-connected to the NIC after boot. If the ethernet cable is connected after the system is up and running, nothing happens - ethtool eth0 shows link detected: no, and you have to restart the network service to let the NIC know that there is in fact a link, and actually connect.
I have a Fedora14 (KDE) box with a brand new Asus motherboard with embedded NIC. Everything works great except the auto-detect of a freshly connected ethernet connection if the link is down to begin with. Am I missing a ethernet link sentinel utility or something, or is this just the way linux works? I have done plenty of research on plenty of posts, and it seems this is a common problem, with no solution other than manually or programatically restarting the network service in a script to detect the link after a disconnect. Thanks in advance for any ideas/solutions. Mike |

I would imagine the reason this isn't implemented across-the-board on most distros is because of this; When you "ifconfig eth# down", what stops the daemon from upping the NIC again? |
Thanks xeleema,
I don't really know what happened, but for some reason, without changing anything in the config, the NIC started negotiating to 1 gig with my router, and began auto-connecting when the cable was disconnected and re-connected again!! Weird! I swear I didn't change a thing.... Gotta love the Linux quirks sometimes... |
Kewl!
Can you mark this as [SOLVED] via "Thread Tools" (up at the top of the page). Maybe hit "Yes" next to any posts that might have been helpful? :) |
