Topic: Losing network connections [resolved]

[4first]

I have recently upgraded from 6.1 to 7.1 (did a fresh install on two new 160GB disks) but the users are experiencing issues with network connections to the server.

I have a feeling that the problem may be the linksys ADSL wireless router network ports causing the problems

Was hoping that some gurus out there might be able to interperate some of the information for me.

Got the following information from the log files;

and the following output from ifconfig;

and the following from netstat -ieth0;

Seems to be saying to me that the NIC is ok so the network issue would then logically be in the switch.

thanks

[munter]

try another network card.

Bet u dont get this error after that.

[4first]

thanks - will try that and let you know

[byte]

What NIC are you using between ?

[4first]

You were spot on munter. A new NIC and have not had the issue since (fingers crossed).

Byte - this was an onboard NIC.

thanks for the help everyone
