Protected WLAN Dont Work, Unprotected Works

[TheLK]

Hardware:
IBM Thinkpad X40 w/ (Atheros Communications, Inc. AR5212 802.11abg NIC)
Distrobution:
Fedora 8 XFCE4
SELinux all set with "permissive" permissions



For some reason I can connect to multiple of my neighbour's unprotected wireless networks.
However i cannot connect to my own network.

I tried:
1. Linksys WAP54G 54Mbps 802.11g Wireless Access Point (WPA Personal encryption) ...'says' connected, but cannot do anything such as browse the internet

2. Linksys WRT54GC Compact Wireless-G Broadband Router (WEP 128bit encryption)......Won't even connect






BTW: On my other labtops running windows it works, and this particular labtop also worked before i converted


Anyone have any clue's whats going wrong here, any suggestions would be great
Thanks in advance

With it connected to yours, open a terminal window and change to root with su - (the dash is important) and type:

ifconfig -a

and post the results

Thanks for any help

Are you using Network Manager or using system-config-network to start/stop your wireless device? Are you using static or dhcp for the configuration? If using system-config-network, check the gateway and dns settings.

Also take into consideration to give 'wlassistant' a try. At my laptop (fujitsu siemens amilo with Intel wlan card) this tool was the only way to connect to protected WLAN networks in fedora 8. (Of course, you also need to have installed wpa_supplicant to connect to WPA/WPA2 protected WLANs.

I tried wlassistant, no luck
wpa_supplicant - 1:0.5.10-4.fc8.i386 (installed) (and running in the services)

Well, you said that you can perfectly connect to unencrypted WLAN (DHCP) networks, right ?
Then lets make one thing clear: your DHCP settings are ok.

So lets focus at the problems with the encryption layer:

That wpa is running as a service does not necessarily mean that wlassistent (or any other WLAN tool) is actualy using it ...

my tip is:
- make sure you have the right security settings (WPA password etc.) made inside the wlassistent
- start wlassistent as root
- start it in a shell and do not force it into background- so you can see what messages the wlassistent is producing (actualy the tool shows all the wlan-commands it is using in the background)
- check for the call of the wpa-suplicant
- check for error messages

here is like it looks at my laptop ( note the 3 lines:
Using wpa_supplicant driver: wext
WPA client started. Waiting for status...
WPA Authorisation successful.)

cheers
