Problem uploading data to a linux host with eepro100+

Mon Jan 24 22:06:54 2000

Thanks for the swift reply!
I never have nil preformance, but close to ...
I've tried to down/up the interface, but that doesn't help.
I've tried to different modes (10/100 FD/no duplex), nothing helps...
I will try the diag program and send this list the results if they are
weird...

I will later try some other old hubs i have lying around, so far i'v only
tried 3com 10/100 auto switches...

Cheers!
