Ip Address Confliction

Hey all,

Well, this happened a few times, but I'm not sure what to do to fix the problem. Most, if not every time I switch from OpenSUSE to Windows, I get a network IP confliction and I cannot use the internet unless I unplug, and then replug in my router. Today, the problem got worse and when I simply got on SUSE, I could not connect to the internet and was having Network problems. I use a Linksys G-Series Router and use an Ethernet connection to use the internet.

Thank you in advance!
