[hilton.britten]

Hi,
i have installed fedora9 on my laptop, its picked up my wireless adaptor as an Ralink RT2500 802.11g cardbus/mini-pc
i have setup in up from the network settings, but when i put in an ip this msessage comes up. Error, some other host already uses address 10.0.20.10 or what ever ip i try and use.
What could be the promblem

Do you have other PCs in this network or is it only this one and the router?
It seems that an other PC is using that IP.

ther is only 1 other Pc on the network which is running win 2000, i have changed the ip afew time but the same msg keeps comin up

Ok, you don't have both your wireless and your wired connection on together do you?

If you're using wireless on Fedora, I strongly suggest you use NetworkManager to handle your connection. This means ticking the box 'Managed by NetworkManager' in the device's page in the network configuration tool and making sure NetworkManager is running. (You may, of course, find that the conflict is arising because NetworkManager is already running and has already connected you...)

Do this as root (capitalisation of NetworkManager is important here):

service NetworkManager start

if that says unknown service, connect via wire to the internet and do:

yum install NetworkManager

and repeat the first command

To make sure that this service always starts, do this as root:

chkconfig NetworkManager on
