I recently did some troubleshooting on a USB wireless dongle hooked up to my Mint distro. I need the USB wireless to access a home DSL wireless modem out to the Internet. The wireless DSL is on 192.168.0.1

I also have a 10/100 ethernet NIC in the computer, for non-wireless connections. The wired ethernet is all 192.168.1.1

I noticed in /var/log/syslog that there are numerous "DHCPDISCOVER on eth0 to 255.255.255.255 port 67" messages.

Since eth0 has a hard-coded IP, I dunno why DHCP is trying deal with it. Can I turn off DHCP activity against eth0? How to do that?

Thanks.

Mint Menu -> Preferences -> Network Connections. Chose your connection and hit edit, go to the IPv4 tab and under method switch from DHCP to Manual and enter the IP.

Thanks snatail1...

I check the settings and they were as you described. Then I checked syslog and the repeating messages were gone. In the interim, the machine was rebooted. Perhaps on reboot the configuration was reset or refreshed. Any way, it's fixed.
