Problem:
Got a brand new HP laptop - HP g62x. Installed ubuntu 10.10 and found that I do not have a wlan interface as one would expect with an active wireless connection.
Thanks to
Great discussion on similar work here @ http://ubuntuforums.org/showthread.php?t=1600498. Just a different card.
Solution:
I used the above thread to do my work - banged my head against the wall a couple of times but it was fun . I am listing down steps that finally worked for me. But before that, my configurations:
- Ubuntu 10.10
- 64 bit
- WPA2 wireless network
- OS was freshly installed and there was no specific customization prior to this
- RaLink Device 5390. (use lspci to see your model number)
- Download the driver from ralinktech.com --> Software --> Linux
- Unzip the download zip file anywhere. I did it in the default Downloads directory
- cd to the 2010_xxx extracted directory
- cd os/linux/
- Edit the config.mk file as below:
HAS_ATE=y (no change, it was originally as is)
HAS_WPA_SUPPLICANT=y (no change, it was originally as is)
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y (no change, it was originally as is)
HAS_ANTENNA_DIVERSITY_SUPPORT=y originally was n -- this was the only thing I modified)- Go back to the 2010_xx directory
- run command 'make'
- Make sure 'make compile' exists without errors. I got an error "too many arguments to format" towards the end of the compile but it did compile successfully eventually. And so I ignored the errors. You would see ***errors*** if the compile is not successful. In which, something went wrong and you may need to tweak the makefile or config.mk files before compile is successful.
- run command 'make install' as root. This is not listed in the README_STA_pci file that comes with downloaded driver zip file. This takes of copying the file to /lib/modules/2.6.35-22-generic/kernel/drivers/net/wireless/rt5390sta.ko. running depmod, creating /etc/Wireless/... folder.
- Edit the /etc/modules and add the line at the end of this file
rt5390sta- Edit the file /etc/modprobe.d/blacklist.conf and add the below line to it...
blacklist rt2800pci- Reboot and you should see an ra0 interface when you run the command 'ifconfig'
- You may have to run '/etc/init.d/network-manager restart' command to have it show in the first go.
- Once, the wireless icon shows up, look for your wireless SSID and there you go surfing
