William, Thanks for answering. The problem that our VLAN users are experimenting is that when downloading or uploading large file, the connection will drop. Some users have difficulties login on their hotmail account. In the same building, we have another VLAN switch connected to an Intel board and the same machines connected to this switch, will not experience that problem. So my feeling is that it is either a problem with the card or with the tulip driver. I am currently trying to drop the MTU on some of those machines and they seem to work better. Since I am using the latest kernel 2.4.29, I am wondering if the tulip driver included is patched. Hopefully it is not an hardware problem, but I used 2 different cards, one a simple linksys and the current quad port card AEI-P430TX with the same behavior.
