    Angry 11.04 - Can see wireless network but can't connect.

    Greetings. I'm a total Ubuntu newbie, so please go gently

    Earlier in the week, I installed 10.10, but had awful problems trying to get the wireless networking working. Upgraded to 11.04, and wireless is sort of working. However, I am unable to connect to my wireless network. It sees the network, but just keeps asking me for the password. I enter this (I have checked that it is correct), but it just prompts again, after a little while. Networking through network cable works fine.

    Wireless network is set up to use WPA-PSK + WPA2-PSK. I have checked, and I do have wpa_supplicant loaded.

    Any help appreciated...

    Thanks

    Phlarris.

    Re: 11.04 - Can see wireless network but can't connect.

    You might try either the wpa or wpa2 but not both selection in the A/P. Sometime Ubuntu has difficulty with mixed mode and certain cards.

    @bkratz: Thanks for that. I'll give it a try tomorrow, and let you know how I get on.

    Re: 11.04 - Can see wireless network but can't connect.

    Still no joy I'm afraid. I've tried setting the A/P? to WPA and then to WPA2, but no joy

    Are there any wireless logs I can look at to see what's going wrong???

    UPDATE: I think that the WPA is a side issue. I disabled security totally on the A/P, and it still didn't connect. I can't anything wrong, and this is a bit frustrating, so any ideas appreciated. Thanks in advance.

    Re: 11.04 - Can see wireless network but can't connect.

    Apologies for replying to my own mails. A bit of further information for if anyone can help. I borrowed a wireless PCMCIA card from a friend, but am experiencing exactly the same problems.

    I get the same thing if I'm connecting via the onboard wireless or the PCMCIA card. This obviously points to either something wrong with Ubuntu which is affecting both, or something wrong with my wireless network. I can connect to the network from XP on the same machine, and other laptops, but no joy from Ubuntu.

    When it's gotten to the bottom of the log, it asks for the password for my wireless network again.

    Any suggestions? Please

    Below is what I'm seeing in the logs:

    Re: 11.04 - Can see wireless network but can't connect.

    Hi,

    I had the same problem as you, but before problem occurred I could connect to my wireless network. Apparently simple channel change in router configuration solved problem.
    Hope this may solve your problem.

    Re: 11.04 - Can see wireless network but can't connect.

    hi
    I just installed Ubuntu too and cannot connect to my wireless network at home (protected). At work though, we have an unsecured wireless network and I can connect without any problems.

    anyone know what might be the problem?

    Re: 11.04 - Can see wireless network but can't connect.

    I have the same problem. Seems like the WEP passphrase is not working. No problem connecting on open networks. It does not seem like connecting to a WIFI should be that hard in 2011, and doesn't seem like a lot of support from Ubuntu on this basic issue.

    Re: 11.04 - Can see wireless network but can't connect.

    Hi, same problem here, can't connect to secured wireless but no problem with unsecured.

    Whatever went wrong it started in 10.10 a couple of weeks ago, and has persisted into a fresh install of 11.04. Pretty sure it's an ubuntu issue as if I boot from a puppy linux cd I can connect to the secure wireless network with ease. All the setting seem to be correct and everything installed as should be. Tried installing WICD instead of NM and it keeps returning 'bad password' when I try to connect (this is not the case).

    Would love to figure this one out, wireless has worked fine with ubuntu on this laptop since I first installed it, strange that it should suddenly stop.

    Re: 11.04 - Can see wireless network but can't connect.

    Anyone has an idea about this? I've tried out an older Ubuntu (10.04 LTS), without success. I also 'betrayed' Ubuntu and tried out Linux Mint 11, without success. It seems my modem does not like Linux? It's the first time I'm installing a Linux-based OS on my laptop, but not yet a big fan of it...
    I'm having it dual booting, and my windows 7 works fine with my modem (wpa protected).
    Any help?
