Maybe it has to do with active FTP connections. The Oberon FTP client
tries to do active FTP, requiring another connection from outside. 
Some firewalls/dsl routers don't accept this.

TCP should be resistant against this kind of problems. 

You could try to reduce the MTU since it is not dynamically adapted
but it should not be needed. 
If you want to try : 
Desktops.OpenDoc AosRTL8139.Mod ~
Search:		NEW(d, AosNet.LinkEthernet, MaxETHFrameSize - 14, 6);
Replace with e.g. . NEW(d, AosNet.LinkEthernet, 512, 6);
Recompile, restart. (If it helps, you can inc the value 512 as long 
as it still helps ;-) But I don't think so :-( )
