Hi Gang, Running into a networking issue. Here is a simplimified view of the network: - one combination DSL modem/router from AT&T feeding into - one five way Cisco hub/switch thingie [*not* a router] with - one Win XP laptop attached by Ethernet and - one Ubuntu desktop wired as well. The laptop is left running 24/7 ... but the Ethernet cable is unplugged when not in use. The Ubuntu box is powered down unless needed. Here is the problem. The laptop runs just fine -- until I boot up the Ubuntu box. The Ubuntu box kicks the laptop offline and 'steals' the connection so that we have to 'ipconfig release' / 'ipconfig renew' the laptop to get it working again. This is not winning me any points at home. ;-( Is there a setting somewhere (hopefully on the Ubuntu box) that I can set to make it 'play nice' and quit stealing the XP's lunch money? Thanks, RonL.
