Intermittent connectivity

I just installed a nortel baystack 310 switch. I have a problem with one work station, a brand new dell.

If i leave the default settings on the port (Spanning Tree Protocol turned on and autonegotiation) the client will be intermittently connected. You can sit there and watch for a few minutes and you'll keep seeing "Network cable unplugged." it connects for, at most, 5 minutes.

If I turn off autonegotiation and set it to full duplex, and disable stp, the conectivity problems cease but the connection is so slow that if you attempt to open a network drive with a lot of files it freezes the computer.

Any ideas?
