MAC network drops

[dmatthews555]

I have a MAC G4 running OS 9.2 connected to a 10/100 hub using TCP/IP which is connected to our HP switches to connect to the internet. After running for 10-15 minutes, it drops the connection. I have a Windows 98 PC connected to the same hub that the MAC is connected to and it stays connected. I have replaced the hub and all of the cables, I have reloaded all of the network pieces of the OS and upgraded from 9.1 to 9.2. The only piece I haven't replaced is the nic card, which is my next step. This has been working fine for 1 month before this started happening. Has anyone else experienced this?

talks about how to tell what speed and duplex your Mac has chosen to speak to the switch with, I suspect the switch is not Autonegotiating with the Mac. I tried to remain child-like, all I acheived was childish.

WHen you say it drops the connection do you mean the mac looses its' I.P. address or you actualy loose the link. When it does drop do you still see a link light on your switch ? Also do you have a level 3 switch if so you might want to turn off spanning tree on the ports that your mac is plugged into, we have had problems with that are selves.

Thanks for the suggestion, I checked spanning tree is disabled. I actualy loose the link, or at least it seems. The link light on both the hub and the switch stay lit and the apple profile says that the link is active and up, but I cannot connect to the network using IE or netscape or retrieve my pop3 email. After reboot it works again for 10-15 minutes before it looses its connection again

Which HP switch do you have? Do you have other Mac G4s on the same switch that are working properly. It sounds like it may be an LACP issue.
