I am having problems with networking on my laptop. FC2 on a Dell Inspiron 5000 with PC card ethernet. I have 2 different ethernet cards and the symptoms are the same with both. 3C562B/3C563B dual network/modem card 3C589D 10base2/10baseT card. On both the choice of network media depends on the dongle attached (10baseT or 10base2) I had no problems with the network interface when running redhat 9. With FC2 it sees the device and loads the 3c589_cs module (I do not remember which module was used with RH9) and properly configures it. I am able to start the network. It links to my switch as 10Mbit full duplex as indicated on the switch leds. Here is the weird part. Sometimes (intermittently) I am able to get out to other machines and other times I cannot. When I do successfully connect it usually after some period just stops communicating. I thought possibly it was an issue with speed/duplexing so I tried mii-tool to see what the parameters of the adapter were, but it tells me there are no mii interfaces available. In fact the error message with mii-tool is "SIOCGMIIPHY on 'eth0' failed: Operation not supported no MII interfaces found" "route -n" properly shows me the routing, both network and default. >From the laptop, ping to the adapter address works, ping to the default gateway does not. >From the other devices on my network everything works except pings to the laptop address. I am certain it is a "failure to communicate" between the pc card and the switch, but I am at a loss on how to proceed. My options seem to be: 1. get this (these) adapter(s) to work reliably (preferred) or 2. get a new adapter. Does anyone have suggestions on how to identify/fix the problem since mii-tool will not work for me? TIA Jeff
