Hello everyone

I upgraded my ubuntu to the new version, but now my W-LAN doesn't work anymore

If i want to configurate my WLAN-Adapter it asks every 30s for the Encription key. I runned out of ideas what i can do to get this working, so I'm posting here.

I tried to configure it manually, but didn't work.
I reinstalled the driver with ndiswrapper, didn't help.
Another problem is that I cannot change the encription of the Router, atm i'm using WPA.

My W-lan adapter is called T-Com Sinus 154 data II, afaik it is build by Siemens.

I hope i didn't forget anything important, so maybe you can help me

Oh and btw I'm still a Linux Newb, so i cannot promise that i will understand everything what you say

Hey could you give some more info, especially what does your system say about it...
In terminal window: sudo tail -f /var/log/syslog

This would show you system log. Now try to connect (via NetworkManager applet?) and collect the messages regarding your connection. Post them. Keep your fingers crossed someone can figure that out.

cheers,

ok here is the log, at first i tried using the "normal" config (i hope you know what i mean):

Seems like the problem is a missing IPv6 router, but what is that and what can i do against it?
For me that sounds like a problem of the router, but my Windows has no problem to connect to the W-Lan so I'm a little bit confused

The problem is with missing key. Which crypto mechanism are you using? I mean WEP/ WPA/ WPA-PSK? :-)
There is no problem with the IPv6 as you do not need any.

cheers,
lukost

I'm using wpa-psk

Hmmm it's weird - i mean it seems like you need second key. That's possible of course but it would be required on windows as well. Are you using TKIP or AES. Perhaps try using TKIP if not using it already. Note that your connection process stop BEFORE an attempt to get IP address so there is no difference in using static or dynamic IP - the problem lies elsewhere.

I had similar problem when my AP was set to use channel '13'. I dunno why ubuntu box failed on the same stage your connection process fails. I changed the wireless channel ID to something like 6 and it helped, but don't ask me why... magic? ;-)


cheers,
lukost

i think I'm using TKIP

well, could you please say me how to change the channel? Even if it is probably pointless... it's better than doing nothing ;-)
