[G4] DP MDD 1.25 ghz built in ethernet (sort of) not working

[C]

Hi there,

I have a DP 1.25ghz  MDD and am having ethernet problems. The built in 
ethernet port is basically not working and extremely slow. Under System 
Preferences / Network / Network Status it shows the green dot and 
states that its active, gives the IP address and connected to the 
internet via built in ethernet. I am connected using DHCP. It will 
check mail (takes 5-10 minutes) but a web page takes forever to load if 
it even will at all.

I have switched cables, reset PRAM and NVRAM, verified and repaired 
permissions, deleted all plists regarding network and the like, 
reconfigured it numerous times, and no luck. Do you think this is a 
software or hardware problem?

This MDD is new to me from as I am upgrading from my G4 AGP Graphics 
(which worked perfect on the same ethernet cable)

I have done everything I can think of and searched all sorts of blogs, 
articles, etc and can't seem to find a solution (other than installing 
a pci ethernet card). Anyone else ever encounter this problem? If I 
install an apple oem 10/100 pci ethernet card will it work at the same 
speed as the built in? Thanks in advance for your help.

Casey
