[SOLVED] "No scan results", Ralink Device 3592

Question

Hi,
I have recently installed Arch on my HP ProBook 4530s, and it has gone great; except that I can't seem to be able to get wifi to work. I've followed the instructions on the wiki, but no dice so far. At first, I tried using netcfg profiles, but it keeps giving "WPA Authentication/Association error." (even though my network uses WEP, and I'm sure I'm entering the correct ESSID/key):
#netcfg -u wireless-home
:: wireless-home up [BUSY]
> WPA Authentication/Association Failed
[FAIL]
## contents of /etc/network.d/wireless-home
CONNECTION='wireless'
DESCRIPTION='BT HomeHub'
INTERFACE='wlan0'
SECURITY='wep'
ESSID='BTHomeHub-A970'
KEY='XXXXXXXXXXX'
IP='dhcp'
# Uncomment this if your ssid is hidden
#HIDDEN=yes
## Uncomment if you are using an ad-hoc connection
#ADHOC=1
PRE_UP="iwconfig $INTERFACE essid $ESSID channel 7"
#TIMEOUT=60
I then tried scanning for networking with iwlist, but that returned no results:
#iwlist wlan0 scan
wlan0 No scan results
I have also tired wicd with wicd-curses, but that also didn't show any wireless networks. I'm pretty sure my network is working properly -- I am able to connect to it in Windows 7 on the same laptop.
The built-in wireless card appears to be detected as "Ralink corp. Device 3592":
#lspci | grep -i net
24:00.0 Network controller: Ralink corp. Device 3592
25:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
I am on 3.0-ARCH and using the default rt2800pci driver. After reading posts about similar problems on this forum, and googling around, I tried downgrading to rt2870sta, which I've installed from AUR, added to MODULES in /etc/rc.conf, while blacklisting rt2800pci; but that made the wlan0 interface disappear completely.
I am now at a loss regarding how to proceed. Does anyone have experience with this card/driver? Am I missing something? Is there something I can do to possibly identify the cause?
Here is additional information (ifconfig output, etc) from my setup:

Answer 1

yes, I been searching the solution as well, as i am using gentoo but kernel drivers doesnt work
I searched one from Russian website, translated into English
I cannot compile it successfully, but let me know if this helps or not
cheers
Solving Problems with Ralink RT3592
I think many familiar with the situation when the laptop identifies all devices except the wireless connection, well, or, as in my case, the device is recognized but not working.
To determine what kind of device is responsible for the wireless connection, you can execute the following command:
$ Lspci-v | grep-i-A 5 "network controller"
24:00.0 Network controller: Ralink corp. Device 3592
Subsystem: Hewlett-Packard Company Device 1638
Flags: bus master, fast devsel, latency 0, IRQ 19
Memory at d4700000 (32-bit, non-prefetchable) [size = 64K]
Capabilities:
Kernel driver in use: rt2800pci
As can be seen, the device is identified as Ralink RT3592, and even found a driver rt2800pci. In the description of the driver does have this card, but the device does not wish to be connected to the network.
Googling, I learned that I am not the only one who have the problem. Many advised to go to the official website of Ralink, download a tarball with the drivers and follow the instructions to install them. Installing the truth was make & & make install, which I personally do not like: I want to know what, where and why is copied to my system, so that if something were to look for the problem easier.
So. The first thing you need - is to download a tarball with the driver from the official site (have to sign the agreement).
The manufacturer's website says that these drivers are suitable for the RT3060, RT3062, RT3562 and RT3592. I tested only on its chip.
Next, unpack the tarball and the directory contains files inside README_STA_pci, where you can read all the installation instructions (including the infamous make install).
Next steps.
1. modify Makefile according to the instructions (I did not need)
2. change the os / linux / config.mk according to instructions (changing settings):
HAS_WPA_SUPPLICANT = y
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT = y
3. make: I gave an error when creating a directory in the root (strange that it's in the make), but the assembly was completed
4. sudo mkdir-p / etc/Wireless/RT2860STA
5. sudo cp RT2860STA.dat / etc/Wireless/RT2860STA
6. sudo cp RT2860STACard.dat / etc/Wireless/RT2860STA
6. sudo cp os/linux/rt3562sta.ko / lib / modules / $ (uname-r) / kernel/drivers/net/wireless/rt2860sta.ko
7. sudo depmod $ (uname-r)
8. add a module to the blacklist rt2800pci for Ubuntu is equivalent to adding to / etc / modprobe.d / blacklist.conf lines:
blacklist rt2800pci
9. reboot
In principle, until the eighth paragraph to see success, you can try the following:
$ Sudo modprobe-r rt2800pci
$ Sudo modprobe rt2860sta
... And restart the network. If everything goes well, we can safely add a free module in the blacklist.
Of course, in an amicable way to compile the package, but the time for analysis of the principles of the assembly, I was not. But such a package is in the repository Russian Fedora (Respect), and the AUR PKGBUILD for too simple.
