WPA/WP2 wireless connection problems

[sreejith_gopinath]

Hello Experts,

I have just installed Ubuntu 10.04 on my HP Pavilion dv5. My laptop has a Broadcom 4312 wireless adapter. The driver for the adapter was installed by Ubuntu as a proprietary driver. The wireless light is on and I can see the available networks, but I am unable to connect to my network. The correct authorization is set(WPA/WPA2) and I have entered the passphrase correctly.

I am able to connect to the wireless network successfully from my Windows login(that is how I confirmed that the passphrase is accurate). The network shows that it is trying to connect, but the wireless authentication dialog(asking for the passphrase) keeps popping up. Incidentally, the same thing happened when I tried openSuSe and Fedora on a spare laptop. The windows systems can connect, but not the Linux systems.

Could somebody please help?

Thanks,
Sreejith

I recently installed a dual boot Ubuntu 10.4 on a Dell Inspiron 5100 alongside Windows XP. The onboard wireless adapter is some off brand dog Orinoco B only card. It never worked on Ubuntu with any kind of security, but did work with NO security.
So I plugged in a USB adapter by Zyxel, which I knew worked on XP. It failed to fire up.
So today, by pure chance I downloaded a document of all Linux commands and worked the network commands in a terminal window. After trying the first one, Ubuntu advised me to download and install UPDATES, which I did. It downloaded about 63 updates for something.
After the updates, the USB adapter fired up using WPA2 security, which I use on my home network. Voila! I have no idea which update did the trick, but the lesson is, for me, that Ubuntu likes to play tricks on the user. You have to think faster than it does.

I am 75 years old. I like to think I am the oldest living human using Ubuntu. LOL
