You may need a proprietary driver for that wifi hardware. Get a wired connection, go to additional drivers and they can be downloaded and installed automatically.

Hi and welcome to the forums and to Ubuntu.

I swear that trouble comes in bunches. You are the fourth WIFI issue this week, which hopefully means that the solution is fresh in our minds

Broadcoms are known to be finicky. Please open up a terminal and do:

wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && chmod +x wireless_script && ./wireless_script

This will download a script, run it, and produce a file on your current directory (usually desktop) that generates a report stripped of personally identifiable info (like your MAC address). Please attach this report to your reply using the paperclip icon in the reply toolbar. It will tell us what broadcom chip you have as well as a wealth of other info that we can use to track down drivers, settings and configurations.

is this the report?

[DuckHook]

Yes, this is the right report. It shows that you are already using the correct driver, so no need to install another.

Please describe in detail how you tried to connect to your home router:

1. What security protocol is your router? Try setting it to WPA2-Personal or WPA2-AES
2. Did you try connecting through Network Manager?
3. Did you doublecheck to make sure your encryption key is accurate?

WEP protocol. where can i find the network manager? yes i double checked the encryption key..

Network Manager is available on the top right of your global menu bar. It is the little icon with the up and down arrows. If you click on the icon, it will open a drop-down box. Make sure "Enable Wireless" is checked, then: Edit Connections...> Wireless

If your SSID already appears then: Select it > Edit > Make sure SSID is correct (case matters in Linux), Mode : Infrastructure > IP4 Settings > Method: Automatic (DHCP) > Wireless Security > Select WPA & WPA2 Personal > [Type in encryption key/passphrase] (remember: case matters) > Save

If not, then: > Add > [Type in your SSID], Mode: Infrastructure > IP4 Settings > Method: Automatic (DHCP) > Wireless Security > Select WPA & WPA2 Personal > [Type in encryption key/passphrase] > Save

If wireless does not come on, reboot your computer.

For above to work, you must have already set your router to WPA2 Personal AES, proper encryption key, saved, then rebooted your router.

<edit>

WEP protocol is the worst protocol in creation and can be broken literally in a few minutes. It lulls you into a false illusion of security while offering none at all. Use WPA2 personal with a good encryption phrase of at least 30 characters, mix of letters and numbers.
