This question already has an answer here:

I have a Fujitsu LH532 and when I installed ubuntu, the network menu didn't have "connect to hidden network" option nor "create a new network". I am not sure how to check my wireless card since when I enter lspci -vvnn | grep 14e4 in the terminal nothing happens except it opens a new line.

Result was:

04:00.0 Network controller [0280]: Ralink corp. Device [1814:3290]

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

We know it's not a Broadcom! Please edit your question to add the result of: lspci -nn | grep 0280. Thanks. – chili555 Dec 1 '12 at 1:18

Please download RT3290 PCIe here: Right-click it and rename it from 2012_RT3290.xx.bz2 to 2012_RT3290.xx.tar.bz2. Then right-click it and select Extract Here. Open the folder that is created and go to os/linux and open the file with a text editor. Change HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n to HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y. Save and close the text editor. Now, with a temporary wired ethernet connection, open a terminal and do:

sudo su
apt-get install linux-headers-generic build-essential
cd Desktop/2012_RT3

Press Tab and the remainder will fill in automatically. Press Enter. Then do:

make install
modprobe rt3290sta

Your wireless should now be working.

I got up to the build essential code but it displays this : root@leo-LIFEBOOK-LH532:/home/leo# cd Desktop/2012_RT3 bash: cd: Desktop/2012_RT3: No such file or directory – Leo Chan Dec 2 '12 at 15:44
In order for the rest of the lengthy name to fill in correctly, press Tab. After it is filled in, press Enter. – chili555 Dec 2 '12 at 16:48
Apologies to bug you again but new problem :/ = root@leo-LIFEBOOK-LH532:/home/leo# cd Downloads/2012_RT3290.xx.tar.bz2 bash: cd: Downloads/2012_RT3290.xx.tar.bz2: Not a directory – Leo Chan Dec 3 '12 at 2:46
You missed a step up there: Right-click it and select 'Extract Here.' Then proceed. – chili555 Dec 3 '12 at 3:10
