Excuse me, but I have another question. In your previous posts you sent outputs for "iwconfig" command.
And one of them looks like:

wlan1 IEEE 802.11bg ESSID:"william"
Mode:Managed Frequency:2.412 GHz Access Point: 56:9E:51:35:25:AA

But another looks like:

wlan1 IEEE 802.11bg ESSID:"william"
Mode:Managed Frequency:2.412 GHz Access Point: 96:1C:A6:92:CF:54

This is output from two different AP, do you have more then one?
If yes, do they have the same DHCP server settings?

Is "ESSID" the router?

Excuse me, but where did you see the word "router" in my post?

I was talking about two different AP.
1. Access Point: 56:9E:51:35:25:AA
2. Access Point: 96:1C:A6:92:CF:54

To be able to go on line your Ubuntu 9.10 has to get network setting from wireless router (AP), it can be achieved by executing (manually or automatically) the "dhclient", which can take network setting and use them to configure wireless interface.

Your posted outputs show that Ubuntu 9.10 can't get network settings from wireless, but can from ethernet.
If it was the same DHCP server on the same router, please check its dhcp server configuration, it should accept requests from wireless clients.




If anyone in this forum has any other ideas please correct me.

Disconnect your wired interface and type dhclient wlan1. If your problem persist give the result of

ifconfig wlan1
netstat -nr

Do you remember how to use http://pastebin.com/, so please, on root console type:
Code:
iwlist wlan1 scan
It may be long output, so use pastebin to post it.
Tell us, which AP do you want to connect to from that output.

Thanks

Thanks, strange output, but anyway.
Can you connect to that wireless router (AP = "Will") through ethernet and check in setup WEB page what kind of encryption is used? Because in output said "Encryption keyn" and nothing else.

Also please post here output of command:
Code:
lspci
I hope you use pci wireless card.


Thanks.
