[Debian Squeeze] Lan Connection Ethernet fail very quick.

[Abou_Ilyes]

Hello All !



I've a problem with LAN-Ethernet connection.

Connection work few minutes, sometime few seconds

I'm connect via NetWorkManager, with DHCP, with Freebox (router of the french ISP Free)


This PC was installed with NetInst method without problems.

With this same PC, with Windows XP, I've no problem with the connection.


I tried to ping google.fr and I saw when the connection failed this message

"sky2 PCI express error"


Here some infos, maybee that can help you... and me

Debian Squeeze, stable.

well could be your router. after the connection drops can you, a: ping the router, b: connect to the router in a browser, or c: retain an ip (check with ifconfig) leased with dhcp from the router?

Right after you lose your connection, open a terminal and execute:

tail -20 /var/log/syslog

Post the output here.
That might shed some light on what's happening.

Have you tried a differnt driver for your LAN?

[Abou_Ilyes]

I'm tried... but not work.

I'll open a new thread about this drivers installation
