Welcome to the BSD world! First, I think I must warn you that this list is dedicated to beginners that want to get started. Technical questions should be sent to freebsd-questions@freebsd.org. And I think this one is worth the effort because you seem to are facing something that can be of interest also to more expert people. However, see below... > Hello, > I have just installed FreeBSD 5.2 on my system. My > network card is National Semiconductors DP 83815 which > is detected properly for interface sis0.

It sounds like your card is loosing its carrier after the driver is loaded. I remember seeing a similar effect with an old evaluation card with a DP83815 when I was working for National Semiconductor: I know there have been at least 2 drivers for Linux (one for the eval card and one for the OEM cards) and they don't seem to be compatible. It may be an issue with the PHY. I eventually had to get rid of this card because I was not able to use it with the 3 systems I was using at that time (W98, Linux and BeOS); I was not a BSD user back then and did not give it a try since. My first bet would be to check the output of the command ifconfig -a You should find an entry for your sis0 driver and some info about what it did. In a second step, if your card seems somehow doing something, try to force the IP address to 10.0.0.1 netmask 255.255.255.0 using sysinstall and see if you can ping 10.0.0.137 (which should be the address of your DSL modem - it is an Ethernet modem, right?). If it says that the network is unreachable, it probably means that there is a compatibility issue with the driver. A third guess is to go to /usr/src/sys and check for the network card driver sources (sorry, I'm not on my BSD machine right now) and type "make install" (without the quotes). in case another driver fits better... Hope it helps Olivier
