Hi all, I am currently upgrading a Linux router on my net and I found some problems with the network card: On this new router I am using a 3com590c which works fine when I use the RJ-45 (10/100) conection. This card has an RJ-45, a BNC and an AUI conector. But I have to use the AUI conection. The fact is that it doens't work with the AUI conection, only with a RJ-45/Twisted pair. I have tried to load the module (3c59x) with "options=1", to force AUI conection, but I dont know if the option is correct (1). The cables are all ok, because the old router is up and running just fine, using a 3com Etherlink II. I cannot use this card because its an ISA card, and I dont have ISA slots on the new machine. Is that possible for this card (3c590c) to be damaged only on the AUI conector? (I do the test pinging a machine on the same network, which is my gateway) Is it possible that this gateway is doing a MAC address filtering and I will have to ask the backbone admin to alow my new NIC? I have very little experience with this AUI conections, so any tips would be very helpfull. Thanks a lot. Gustavo Gouvea
