[SOLVED] WIFI connection is not working

Yet Another WIFI issue
When I try 'wpa_supplicant -i wlan0 -c <(wpa_passphrase "mylongssid" "mylongkey")'
I receive this error:

Successfully initialized wpa_supplicant
wlan0: Failed to initialize driver interface

I was on my wifi at home this morning surfing the web and then I went to school (So I hopped to a different WIFI in other words)
It seems no matter what I do with netctl, iw, wifi-menu, and ip link that nothing works.  Currently I do know how to set wlan0 up/down, restart my netctl profiles, display iw stuff, scan with iw, etc.
But I do not seem to know enough.  Can anybody help by providing some debug commands?

Re: [SOLVED] WIFI connection is not working

Please edit your post and change your title to one that actually describes your issue: https://wiki.archlinux.org/index.php/Fo … ow_to_Post

Step through the manual connection process to determine why the interface is not up.

wpa_supplicant is the manual connection process?  No?

Re: [SOLVED] WIFI connection is not working

wpa_supplicant is the step where I receive an error.  I did all the other steps before my first post, except for the adhoc stuff.

Re: [SOLVED] WIFI connection is not working

What card and driver are you using? What drivers does your wpa_supplicant support?

Re: [SOLVED] WIFI connection is not working

Some Broadcom chip that has b43 firmware.
I will post the output of the lspci in a few moments.  I have to transfer some output via a flash drive.
Here is the output of some stuff:
http://pastebin.com/8vNyHZWs

My drivers worked fine this morning at my house, and they usually work at school after a reboot.  So I am not sure why you need driver info.  My question was what debug commands can help me diagnose my wpa_supplicant error?  As in what log files can I check?  If I could find a log with a more descriptive error, I might be able to fix my WIFI.  Or possibly some logs for netctl?  I really do not know, since networking is usually magic in all the easier linuxes I have used in the past.

Thanks for the really quick responses by the way   I have never had such a fast help response for any other distro.

Edit: I should note that both my home and school networks have the same type of WPA security.

Update: When I booted my labtop at home, I ran wifi-menu and voila my home network was working.  I will try the WIFI at school again tomorrow and post another update after that.

Update 2: Running wifi-menu at school worked today.  I have no clue why it did not work yesterday.  (I really should setup netctl-auto)
