I'm running openSuse 10.3 on my laptop which has both a wired and wireless NIC and I'm using Network Manager. When I'm at my desk I used the wired connection. Up until today I was able to connect or remove the network cable and it would connect or disconnect wireless accordingly. I had my laptop on wireless away from my desk for the long weekend. Today I've been experiencing disconnects with the wired network. I have not found any reason for it. I've tried running a continuous ping in a terminal and I will see this around the time of the failure: ping: sendmsg: No buffer space available That will change to ping: sendmsg: Network is unreachable Network Manager says the network is disconnected. Then it appears to reconnect it, but ping continues to fail until I manually turn off the network and restart it manually. The only thing I see in messages is: kernel: NETDEV WATCHDOG: eth0: transmit timed out. Anyone have any troubleshooting suggestions? I know my network drop is good, but I have tried another just for good measure. Any help is appreciated.

Network Manager says the network is disconnected. Then it appears to reconnect it, but ping continues to fail until I manually turn off the network and restart it manually.

This happens to me occasionally. Every time, it turns out to be that my router has crashed. So I go downstairs, pull the power for 5 seconds or so, and by the time I'm back upstairs, the network is up again.
Any help is appreciated.
Thanks, James

Sounds like a different issue than mine. I'm connecting to a 10/100 or a Gigabit switch, not even directly to my router. Other machines on the same switches do not lose connectivity. My laptop loses connection to the switch. Thanks, James -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Powersaver? Many laptops are configured to shut down the wired nic when powersaving kicks in. -- ----------JSA--------- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Nope. I can be actively using it and the little message will pop up in the bottom right corner that the connection was lost. It'll even come back a bit later and say the connection is back up, but it's not. It doesn't restore unless I manually uncheck "Enable Networking" and recheck it. Maybe I should try turning Network Manager off? Thanks, James -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I tried turning Network Manager off and still had the same problem. The internal NIC is Intel 82566MM Gigabit adapter. Problem happens when connected to my gigabit switch or one of my 10/100 switches.

I removed irqpoll and pci=routeirq from the kernel parameters and my NIC has stayed connected for a couple hours now. These two items were added in attempts to get my internal card reader working.
