Hey there, first, let me say thanks for reviewing my question.
I've been tackling trying to get this Ubuntu 12.04 precise pangolin machine connected via wifi for the better part of a week. Let me preface the next paragraph by noting that I am by no means an expert in linux.
I unfortunately do not possess the ability to connect directly to my router with a wired connection; this has compounded my issue. I've tried connecting to my network with several different wifi cards before finally reviewing a list of supported devices out of the box.
I went down to my local store and picked up a Sarbent a11n which said it was supported (Ralink chipset of some sort? rtl8192cu?).
Anyway, I came home and plugged'er in. Right out of the box it worked and found my network. I attempted to connect to it and it and it attempts, then says disconnected. It does this quite a few times before it no longer attempts a connection.
I've done sudo cat /var/log/syslog | grep -e ipw -e firmware -e wpa -e wlan -e etork | tail n-55 and see that it continually faces a warning:
ggtr-server networkmanager: <warn> Actvation (wlan1) failed for access point (belkin.2ca), which is prefaced by:
ggtr-server networkmanager: <warn> Activation (wlan1/wireless): association took too long, failing activation.
Here's the output from the requested commands to be included when posting for help (Sorry if mispelled in some areas, had to type it out by hand)
