I just bought an HP Pavilion g6 laptop and I installed Natty Narwhal alongside Windows 7. In Windows 7, my WiFi works perfect but in Ubuntu it absolutely (no matter what I do) won't detect my home WiFi network.



Here is the output of "lspci":

The RT5390PCIe is not directly supported by the current Natty kernel.


You will need to download some driver source code and patch the Natty kernel.


Unfortunately you need to be aware, everytime the Natty kernel is updated, you will need to repeat the following instructions:



  1. Download the linux driver (RT5390PCIe) from Ralink.



  2. Extract it. The files will be extracted to 2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO folder.



  3. Download all the patches except the x64_86 patch, assuming you have a 32-bit system, from opensuse website.



  4. Copy the patches to the folder – 2010_1216_RT5390_LinuxSTA_V2.4.0.4_WiFiBTCombo_DPO



  5. Goto the folder.



  6. Make the following change in /os/linux/config.mk file – HAS_ANTENNA_DIVERSITY_SUPPORT=y (originally was n)



  7. Now run the following commands in terminal:




patch instructions


patch -p0 < rt5390sta-2.4.0.4-config.patch

patch -p0 < rt5390sta-2.4.0.4-convert-devicename-to-wlanX.patch

patch -p0 < rt5390sta-2.4.0.4-reduce_debug_output.patch

patch -p0 < rt5390sta-2.4.0.4-remove-potential-conflicts-with-rt2860sta.patch

patch -p0 < rt5390sta-2.4.0.4-return_nonvoid_function.patch

patch -p0 < rt5390sta-2.4.0.4-WPA-mixed.patch

sudo su

cp RT2860STA.dat RT5390STA.dat

mkdir -p /etc/Wireless/RT5390STA

cp RT5390STA.dat /etc/Wireless/RT5390STA

make clean

make

make install

modprobe rt5390sta

exit
