Hi guys,
Thanks for the responses, it's not the auto-negotiation, at the 
particular time when I sent the details, I had it plugged into an old 
hub, the problem occured also when I plugged it straight into my laptop 
at 100Mb full duplex, I currently have the net4801 running in dhcp mode 
on the wan interface, connected to my modem/router, and it's working 
like a dream, which leads me to believe it's the mtu as Paul suggested.

I will test again and get back to you guys shortly,
