Cannot connect to secure Wireless in Kubuntu 9.10 ...

[Guest]

I am playing with 9.10 on my laptop. Using KDE, I am unable to connect to any secure networks (have only tried WPA) It keeps prompting for the password.

However, using Gnome on the same machine, I connect fine.

I can connect to unsecured networks without issue.

Any thoughts on fixing this?

Thanks.

My recommendation is to use the network management app from gnome for now. You can add it to Autostart in System Settings if you'd like.

Or hit alt-F2 and enter: nm-applet

It seems it's just problems with the KDE network manager plasmoid.

Others prefer to remove the network-manager system altogether, and use WICD instead. Haven't tried that myself.

There is more info in this thread.

Go here and vote-up the bug.

Thank you. Done and voted up. Bug is marked confirmed with my vote

Now to get my mobile USB modem to work in KDE, it also works in the nm-applet but not KDE plasmoid

After five years of using my Linksys WRT54G in the WEP mode (lazy, I guess) a switched to the WPA mode a few days ago.

I use the nm-applet and noticed that it asked me several times for the password after I setup up the connection. After a couple times a dialog appeared which gave me the option to automatically start. I checked it and ignored other popups. After a minute or two the tower with several rings appeared and my WPA connection was established. It has never failed to make the connection during boot up since then.

I am one of the people who switched to wicd. Ever since I did, I have not experienced serious network connection and wireless problems.

Wicd is running on 9.04 (desktop), 9.10 (desktop) and on a laptop. Desktop has Atheros chipset; the laptop a built-in chipset. No problems with either. Wireless router is a Linksys WRT54-G.

I will stick with wicd at least until KDE finally has managed to produce a working network manager.
Wicd now is in the Kubuntu repositories.

Nothing wrong with that approach. My wife runs an Acer 3004Li laptop and her wireless won't work with nm-manager, so I use wicd on it for the same reasons you are using it. Since it works well and isn't broken I am not going to fix it.

Hi,

my only problem with wicd is mobile broadband connections which it doesn't support.
Sometimes i also need to connect to a VPN (PPTP) to my office and nm-applet from network-manager-gnome supports both.

Best Wishes.

+1 for WICD.

I tried "nm-applet" in the alt-f2 and nothing happens?

You might need to have the gnome network manager package and assorted libraries installed, you can try:

sudo aptitude install network-manager-gnome

That should install the required gnome libraries and nm-applet.

Re: Cannot connect to secure Wireless in Kubuntu 9.10 ...

...but that dosent solve the problem of getting online to download said packages anyway....

Can't someone just make a .deb file with all the files in it, so you know, we can pop it in a USB stick or something?

Or better yet, use another network manager?

I was only able to connect in 9.04 thanks to overloading the program with requests to connect, which didnt let it time out and thus connected me (but installing updates DOES 'fix' this 'bug')

I'm not particulally enjoying the prospect of either removing my WPA key or switching between 9.04 and 9.10 :/

Re: Cannot connect to secure Wireless in Kubuntu 9.10 ...

Assuming you also have a wired connection, you can always open a command prompt and do a 'sudo dhclient'.

It will find and check all network connections and eventually connect you to the wired network. From there it is easy, of course.

As I write this I am running Karmic APHA3 as a LiveCD.

Jaunty's knetworkmanager connects fine to my Linksys WRT54G wireless router in the WPA-PSK mode with an ASCII password. Karmic cannnot.

I dropped to a Konsole and issued;

sudo iwconfig wlan0 essid GreyGeek key s:mypassword

and it returned:

Error for wireless request "Set Encode" (8B2A) :
SET failed on device wlan0 ; Invalid argument.

"sudo iwconfig wlan0 essid GreyGeek" works fine.

"sudo iwconfig wlan0 key s:mypassword" does not.
