Common Problems

How do I force the adapter to run at a particular speed?

How do I change the IP address for my network interface?

How do I change the hostname for my network interface?

How do I configure another IP address or subnet for my network interface?

How do I know if my network interface is up? I can not ping the device.

How do I determine the current speed of my adapter?

I moved the board to another slot, but ifconfig does not work

Is the new card recognized by the system?

Which instance did the network adapter move to?

Error Messages
