I installed from a USB linuxlive drive, at first when I did try Ubuntu, the wireless didn't work, so I thought it might work if I installed and ran along side windows, prior to the install the wifi started working, but install didn't take. since wifi was working I decided to go ahead and replace windows (XP) so installed. So, now wifi works if I run linuxlive from USB, but if I try to run form computer only, disconnects. I type in iwconfig and it says no wireless extensions. Anyone know how to fix this?

1. Check and see if your device(s) has an LED light and whether it is OFF or ON. Some newer OS's will switch your device ON and not tell you.
2. IF you have connected wifi devices before and/or used NDIS wrappers before skip this step. Use a second computer and perform the NDIS wrapper install (should NOT be needed on Ubuntu 14.04...but some people download all kinds of variants).
3. If you do not have a second computer or access to a second internet system...and you DO have windows in dual boot with your system...check the wifi connection there and validate your signal quality. DO NOT perform any modifications to an existing working wifi setup...or jump to
a second Linux partition (assuming you have one)..before checking your
14.04 system you installed for a working wifi.
4. IF you have a strong signal in windows...and IF that is a broadcom or similar driver...then the next steps are easy...boot up 14.04...see if
if sees your device...if not go back to windows..use the USB removal program..EJECT the USB wifi device...and then boot back into 14.04. You
may get a new screen or "flashing window/device"...plug in your wireless
wifi into the USB terminal again..and see if the indicator changes.

If you did NOT get a response, you may need to download the drivers and use NDIS wrapper...read the instructions on those pages carefully...you might have a device that cannot use NDIS wrappers and/or have a driver that microsoft's "compatibility code program" won't let you use with that
set of drivers..Broadcom's should still work..but I have a old Belkin that when you load the "brand new 64-bit drivers"..shuts down the NDIS
wrapper program (Microsoft's 'user protection program').

Post back here if any of this helped..or you found another solution or..

YOU STILL HAVE PROBLEMS. WW
