What is the working distro _EXACTLY_? "some kind of basterized Debian" is not enough. What does dmesg say about the DP8315? Have you looked at the Debian ifconfig? Is the same cable being used? Same cable path? I found a 10 Mb hub in a customer setup that was hidden behind the next desk where the Bad Boy computer plugged in. The computer thought the connection was 100Mb but it would only work at 10. Sorry, gotta go. Google the distro and DP8315. -- gypsy _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
