Hello xiaoyaozi

Firstly, I have a 3945 that connects well to a WPA encrypted access point but some people are not so lucky.

If your access point does not broadcast its ssid you should consider changing that just as an experiment. Some people have reported that once the machine has connected once it will reconnect after the ssid is hidden again

Secondly, there can be more that one process trying to control the card and there are some things to check.

I assume you are running Gnome as your desktop.

From the System Menu - Administration - Services, make sure that NetworkManager is set to start at boot and is running.

From System Menu - Administration - Network, highlight your wireless card and click 'Edit' from the toolbar.

Make sure that the card is NOT set to "Activate Device when Computer Starts". If your system is up to date there will also be an option to choose "Controlled by NetworkManager", make sure that is selected.

See if those suggestions help otherwise we will all think again.

Are yo uusing NetworkMAnager.

There is a bug. When it repeatedly asks for the key, DO NOT provide it. Instead click on the NM icon in the panel and select "connect to new network" and fill in the details.

Also see this !

hi bbfuller, thanks for your help, but it can't work well when i followed your suggestion.
and now the network access need static ip to connect instead of DHCP
so first I set the correct IP and DNS as what windows do
then start the NetworkManger service, and enter the password when it ask for wpa key.
it connected successfully in a few seconds
but the IP and DNS have been changed by the service, and can not connect to www
so my question is how can I start it without change my static ip and DNS?

also thanks stevea, I just tried what you said but failed unfortunatly.

Hello xiaoyaozi

What I suggested should have worked when you were able to use dhcp as a method of obtaining an ip address.

I haven't tried, but from reading on the forum I understand that the NetworkManager software won't work with static ip addresses.

I believe your only choice for that is going to be to disable NetworkManager from the "Services" application mentioned earlier and to make your connection manually. From what I read NetworkManager may have the facility for static ip addresses in Fedora 9.

This howto:


at least tells you how to control wpa_supplicant manually.

I assume you will have to configure your card from the "System - Administration - Network" aplication and then add the control for wpa_supplicant as the howto.

Not sure how that will work out as I've never had to do it.
