remedy for many errors in networking?

[Verlager]

The problem is that, with the eth0 wired LAN cable detached, the ifconfig command reveals trouble (errors). But as I see now, ifconfig reveals 800,000+ errors on my other ZW computer. So... as long these errors are part of the system, I can accept them. But is there anything I can do to get rid of the errors?

After a reboot, with the eth0 patch cord connected,  ifconfig reveals this:
