rt5390 driver ubuntu 14.04

Question

How can I install the wlan driver for my rt5390 in ubuntu 14.04

I have already tried this link but no help. http://www.upubuntu.com/2012/02/how-to-install-drivers-for-ralink.html

Answer 1

The patch line should be:

patch -p1 <rt5592sta_fix_64bit_3.8.patch

This editor confuses < and leaves out the rest of the line :-)

Thanks for the links, wasn't able to find available files

Answer 2

Here is what I've done on my own system. It works better than original driver.

1. download archive : https://github.com/Inglebard/2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO_v2/raw/master/2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO_v2.tar.bz2.bz2
2. extract archive
3. cd 2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO
4. download : https://raw.githubusercontent.com/Inglebard/2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO_v2/master/patch/rt5592sta_fix_64bit_3.8.patch
5. patch -p1
6. make sure /os/linux/config.mk reads HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
7. make
8. sudo make install
9. modprobe rt5390sta

You may need to to install and configure dkms to build automaticaly wifi drivers when kernel change : https://help.ubuntu.com/community/DKMS

You may need to disable some other drivers in /etc/modprobe.d/blacklist.conf

## Blacklist conflicting kernel modules
blacklist rt2800pci
blacklist rt2800lib
blacklist rt2x00usb
blacklist rt2x00pci
blacklist rt2x00lib
blacklist rt2860sta
blacklist rt3090sta

Note : I don't know why but sometimes (it's happens rarely), driver is unable to find wifi hotspot and write this in syslog :

GetDesiredTssiAndCurrentTssi: BBP TSSI INFO is not ready. (BbpR47 = 0x94)
RT5390_AsicTxAlcGetAutoAgcOffset: Incorrect desired TSSI or current TSSI

And you may have to shutdown by power button of your machine. (If someone know why, I'am interressed)
