Your system is a CLIENT. So you think the Linksys router remembered the old address, 192.168.1.7, of my laptop, and gave it out despite the fact that its local IP address is 192.168.2.1 ? I think if it was giving out an address it would be in the range 100-149, which is the range it says it offers. (I'm running the standard Linksys software, and there doesn't seem to be any way of registering address on it, as in /etc/dhcpd.conf .) > Now you seem to be mixing things up a bit.

On my CentOS desktop this LAN is on the interface eth1, and is connected by ethernet to the router; on my Fedora laptop it is wlan0, connecting by WiFi. > What is the bootproto for eth0?

As I said I have BOOTPROTO=dhcp on my laptop, which I agree should mean it gets its IP address from the router. But it doesn't seem to be doing that. My experience is that if I wait several hours and constantly re-boot my laptop, it will in the end get a new IP address in the 192.168.2.100-149 range. It seems there is some kind of inertia about changing IP addresses. It's as though there is a lease somewhere and I have to wait for it to expire. Maybe people don't often try to change the address of a machine, and so the issue doesn't often arise? -- Timothy Murphy e-mail: gayleard /at/ eircom.net tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
