Linux stopped connecting wirelessly

Just recently installed UBUNTU 12.? (the newest to date), and was loving it. Randomly it stopped connecting to my home network. It completely stopped searching for wireless networks in general. I don't think its my wireless drives or whatever, as it connected fine before. I tried a terminal command, and it asks me to type my pw in, but it doesn't register the typing. I have tried just typing it and hitting enter but it says incorrect pw or whatever. Please help, I do not want to switch back ti windows. I am not dual booted. And his happened after attempting to install java. Which is a total pain -.-
Peace and love, ~hipqy

there are no characters shown when you type a password in the terminal.

When using sudo you're asked for your userpassword, when executing a command as root, you're probably asked for the root password, it would be good if you knew which command you've typed in.

I don't think that installing Java has something to do with your wifi.

Please post the output of

Code:

lspci -k | grep -iA3 net

and if this shows nothing (or no information about your wireless adapter, please execute

Code:

/sbin/lspci -k

and post here the three lines about your wifi adapter.

Also please post the output of

Code:

sudo iwconfig

and

Code:

ifconfig

Thanks for the speedy response! Unfortunately I just arrived at work. I will post back at around 6a eastern.

Sorry the format isnt exact , im using my cell phone.

Well, Broadcom adapters often have unstable drivers. Better to look for the output of the other commands.

I'm just one guy, but I have three Linux computers with Broadcom chips. I've not found them unstable, once I got them working.

Linux Wireless dot org has a long article on Broadcom's B43 series, which includes a number of diagnostic commands you can use to investigate this:
