I cannot log into my wifi on my dell latitude.

I have to hard wire it to my other laptop to get on the Internet. Does anyone have any idea about how to get the wifi to work?

Welcome to Ask Ubuntu! We need more hardware information to help you, can you look at this question and then edit your question adding the information. –  Jorge Castro Jan 3 '13 at 14:28
    
What have you tried apart from the commands there? List obvious actions like "applied all updates", "tried version x.y of Ubuntu too". Anyway, it seems your radio killswitch isn't detected (or not present). Try some options here: My WiFi adapter is not working at all. Where to start troubleshooting? –  gertvdijk Jan 3 '13 at 14:35

With the ethernet connected, please do:

sudo apt-get install linux-firmware-nonfree
sudo modprobe -r b43 && sudo modprobe b43

Detach the ethernet and your wireless should be working.

had this problem with windows 7 but went in the settings and pulled up available wireless connections and it worked switched to ubuntu and the problem is back must be the laptop itself –  John Hartel Jan 3 '13 at 15:07

any advise @chili555 you seen to be on the right track i go to network connections and wireless is there and airplaine mode is on i turn it off but still cant turn on the wifi close out come back airplane is back on –  John Hartel Jan 3 '13 at 15:42
    
As an experiment, try: sudo modprobe -r dell-laptop; sudo rfkill unblock all. Now is airplane mode off? Now can you connect? –  chili555 Jan 3 '13 at 16:49

try this and its works for me for my dell 5220

Several things are wrong here. 1) on different hardware 2) link-only 3) Not clear to what part of the page you're referring to 4) Arch Linux isn't Ubuntu ---- Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  gertvdijk Jan 4 '13 at 22:33
