Can't connect to internet when there's a password. Ubuntu 13.04 and Realtek 8723.

[phoreeyes]

I just installed Ubuntu 13.04 yesterday from a USB key, When I attempt to connect to my home network after I enter the password and wait a few seconds a message pops up notifying me I have been disconnected from internet... Although I was never connected. The password is entered correctly and the internet works just fine on my Ipod. When I connect to the free wifi (no password) at mcDonalds the internet works fine. I have seen http://askubuntu.com/questions/28668...-wifi-on-13-04 but the answer there did not help solve my problem and I have a realtek 8723 not 8188. I also upgraded my kernel to 3.9 as someone suggested that may help. It did not. Any help would be greatly appreciated, thanks very much!!

It's an authentication problem. A common Ubuntu bug. Try changing the password to a hex or completely remove the password. I am not 100% sure if the hex will work but removing the password will. Or just connect to a wired connection.

which password? for the keyring? note keyring password is (usually) not the same as user password.

The password is the internet password. Unfortunatley the internet is for the entire apartment building and I'm unable to remove/change the password (although I'm sure that would work as I can connect whenever there isn't one). Is there any other way around this?

You mean the network key for wireless?

[phoreeyes]

Yes, I have the correct password and all my other devices can connect fine.

Please show us the card and driver in use -

lspci -nnk | grep -iA2 net

If it is a usb device, then -

lsusb
lsmod

If you know the driver in use, please also post -

modinfo <driver name>

[phoreeyes]

I'm at work right now, will update with that info when I get home. Thanks for the help!

Also, I have noticed in the past that sometimes it's best to go into network manager/edit connections and delete any definition that shows there for your network. Then wait a few minutes and try to connect again. It will ask for a password at that point. Please take a desktop snapshot and post it back here. Then enter in your password and when it fails take another screen shot and post it back here as well.
