================================================== ========================

This is a brand new laptop on which I installed Ubuntu 12.04. The wireless card is not recognized. I tried to follow the instructions presented in the following posts:

http://ubuntuforums.org/showpost.php...7&postcount=42
http://ubuntuforums.org/showthread.php?t=1645716

but I wasn't successful. When I install Ubuntu 12.10, the network card is picked up as RT2800 and it works fine as noted in this thread http://ubuntuforums.org/showthread.p...u+12.10+RT5390 Unfortunately, I do need 12.04!

The driver that I downloaded is: 2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO_v2. bz2.bz2

1. Unzipped bz2 file mentioned above.
2. Changed the following in .\os\linux\config.mk
HAS_WPA_SUPPLICANT=y #was already y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y #was n, changed to y
3. Ran the following:
sudo make
sudo make install
Both ran without errors.
4. Then
sudo rm -rf /etc/Wireless/RT2860STA
sudo mkdir /etc/Wireless/RT5390STA
sudo cp RT2860STA.dat /etc/Wireless/RT5390STA/RT5390STA.dat
5. When I look under /lib/modules/3.2.0-34-generic/kernel/drivers/net/wireless
I do see that rt5390sta.ko was copied there with the right timestamp.

6. In /etc/modules I have added rt5390sta

7. In /etc/modprobe.d/blacklist.conf I have
blacklist rt2800pci

I have rebooted the laptop but I do not see the Wireless adapter in the terminal or UI. I would appreciate any help with this. Thanks.

Is it possible that the driver you built doesn't actually drive your device (he asks rhetorically)? Please run:

Code:

lspci -nn | grep 0280

The vendor and device ID will appear, possibly 1814:539b. Now let's search the module you built for that ID:

Code:

modinfo rt5390sta | grep -i 539B  <-or whatever the last four characters you found

Yes? No?

We are fascinated but not surprised at your report.

EDIT: This is probably fixable with a heatgun, duct tape and pop rivets.

Thank you for your response.

You seem pretty adept, so I'll explain it thus. I have no idea this will actually work, but let's take a shot. In the package you extracted, open the file os/linux/pci_main_dev.c with a text editor. Add your device about line 75 like this:

#ifdef RT5390
{PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5390_PCIe_DEVICE_ID)},
{PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC539F_PCIe_DEVICE_ID)},
{PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5392_PCIe_DEVICE_ID)},
{PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC539B_PCIe_DEVICE_ID)},
{PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5362_PCI_DEVICE_ID)},
#endif /* RT5390 */

All before and after are unchanged. Make sure the spacing, brackets, et al are perfect. Proofread, save and close the text editor. Now recompile:

Code:

cd Desktop/2011_1007_RT5390_RT5392_Linux_STA_V2.5.0.3_DPO_v2  <--or wherever you extracted the package
sudo su
make clean
make
make install
modprobe -r rt5390sta
modprobe rt5390sta
exit

Any improvement?

Search for NIC5392_PCIe_DEVICE_ID in all directories.

Code:

$ grep -r -n NIC5392_PCIe_DEVICE_ID .

./include/chip/chip_id.h:60:#define NIC5392_PCIe_DEVICE_ID 	0x5392
./include/chip/rt5390.h:67:#define NIC5392_PCIe_DEVICE_ID 	0x5392
./os/linux/pci_main_dev.c:75:	{PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC5392_PCIe_DEVICE_ID)},
./os/linux/rt_rbus_pci_drv.c:1380:	(device_id ==  NIC5392_PCIe_DEVICE_ID)	||
./os/linux/rt_rbus_pci_drv.c:1669:				case NIC5392_PCIe_DEVICE_ID:

Duplicate that line and replace 2 with B.

Code:

$ grep -r -n NIC539B_PCIe_DEVICE_ID .

./include/chip/chip_id.h:61:#define NIC539B_PCIe_DEVICE_ID	0x539B
./include/chip/rt5390.h:68:#define NIC539B_PCIe_DEVICE_ID 	0x539B
./os/linux/pci_main_dev.c:76:	{PCI_DEVICE(NIC_PCI_VENDOR_ID, NIC539B_PCIe_DEVICE_ID)},
./os/linux/rt_rbus_pci_drv.c:1381:	(device_id ==  NIC539B_PCIe_DEVICE_ID)	||
./os/linux/rt_rbus_pci_drv.c:1670:				case NIC539B_PCIe_DEVICE_ID:

Then followed the steps that you listed. The code does not compile unless ALL the above changes are made.

And it works! I have been testing the connection for the last few minutes and it seems OK! I really appreciate your quick response and the suggestions.

Excellent. Thanks for your careful explanation which, I'm quite confident, will be used again may times. Glad it's working.

CAUTION: This fix is for device ID 1814:539b only!

Update: the driver that was created based on the modifications listed above was very unstable and resulted in many other issue. I had to remove it within a day.

The following solution has worked for me -- http://ubuntuforums.org/showthread.php?t=2083204 (using the back port mentioned in the last post). Installation was very fast, and the wireless card worked flawlessly after I rebooted the machine.
