no wifi on install...waiting for network configuration

[snippyv]

Hello.

I've tried 12.04 on a live USB and everything was fine...but when I have installed it I have wifi problems.

On boot I get...

1) Waiting for network configuration.
2) waiting up to 60 more seconds for network configuration.
3) Booting system without full network configuration.
4) I then log on.
5) The system shows my wifi router.
6) I click on it to log on.....and I get the message "Disconnected-you are now offline".

Can anyone offer any suggestions???

Why would the wifi work on the live usb and not the install?

ps...I am using 12.04 instead of 11.10 as I had that black screen bug at log on when I tried 11.10.

Thanks.

The "click to log on.. then get message 'disconnected - you are now offline'" error sounds reminiscient to me of an incorrect passphrase. Try going to Edit Connections (accessible by right-clicking the icon generally situated top-right), finding the wifi connection and removing/readding the passphrase used, ensuring that the one you type in exactly matches what you have configured in your router.

Did the wifi connection work before? Do you have the right driver installed?

It is definitely the correct pass phrase.

Wifi worked fine under the live usb.

So is this an install issue...as there the system shows 'waiting for network configuration'at boot?

I've created a new live usb...checked that the wifi works.....which it does..and tried a fresh install.....all with the same results.

I have also tried to connect with a wired cable to the router.....again no luck.

Any help much appreciated.

Thanks.
