This is a truly strange problem that i have been looking for an answer to for some time and i hope someone can help me.

My system is a triple boot system (Windows XP, Fedora Core 6, Kubuntu 6.10) and i live in an extremely wifi saturated area. I would like to use my highspeed ethernet connection (which works in Windows XP, haven't tried FC6) but whenever i disable wifi i cannot connect. My ether net is DHCP and i only need to login every seven days. here's the ifconfig -a output:

does anyone have any ideas? If i can provide any more information to help figure this out please ask. Thanks

The obvious thing I see is the mask for eth0. It is set to net addr:192.168.1.104 Bcast:192.168.1.111 Mask:255.255.255.248. The normal mask would be 255.255.255.0 like it is no ath0. You have most of the host bits masked off. Set it like ath0, and try again.

will that cause a conflict between the two devices? And if the network is DHCP how can i set those values manually? Thanks for the quick reply

ath0 Link encap:Ethernet HWaddr 00:0F:EA:91:5B:AE
inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0
eth0 Link encap:Ethernet HWaddr 00:90:F5:38:13:00
inet addr:192.168.1.104 Bcast:192.168.1.111 Mask:255.255.255.248

If you keep eth0 at 192.168.1.104/29 and you want ath0 in the same classC then you could put ath0 like this:
192.168.1.102 , netmask 255.255.255.248, broadcast 192.168.1.103
(with ubuntu you have to look in /etc/network/interface, man interface)

Or you set both of them at 255.255.255.0 but then you have to use 2 different classC: 192.168.1.x for eth0, 192.168.2.x for ath0.

"camorri" is offering the error resolution. "nx5000" is offering a choice to proceed with. YOU may use "netconfig" or "netconfig -a" to change YOUR Network data. Also "lspci", "lsusb", "modprobe", "insmod" and "Ethtool" will offer data output to verify presence and accuracy. Good luck.
