 Posted: Fri Mar 16, 2007 2:51 am Post subject: configuring WPA on a ralink chip |
 |
|
I am trying to get my wireless card set up. It could be a problem with the driver/wpa_supplicant, but I wonder if I am not setting up my configuration files correctly (I am largely guessing and example-following on that score). I am hoping someone will point out an error in my conifg files; otherwise, I will have to blame my driver.
/etc/conf.d/net:
| Code: |
iface_eth0="dhcp"
dhcpcd_eth0=""
modules=( "wpa_supplicant" )
wpa_supplicant_rausb0="-Dralink"
|
/etc/wpa_supplicant/wpa_supplicant.conf
| Code: |
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
ap_scan=1
network={
ssid="<MYESSID>"
proto=WPA
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP WEP104 WEP40
psk=<MYPSK>
priority=2
}
|
I have /etc/init.d/net.rausb0 -> /etc/init.d/net.lo, when I do "/etc/init.d/net.rausb0 start" I get
| Code: |
* Starting rausb0
* Loading networking modules for rausb0
* modules: apipa arping ccwgroup macchanger macnet rename |wpa_supplicant essidnet iptunnel ifconfig system dhcpcd ip6to4
* wpa_supplicant provides wireless
* ifconfig provides interface
* dhcpcd provides dhcp

* Starting wpa_cli on rausb0 ... [ ok ]

|
Other postings suggest the ioctl messages are not important.... ???
If I do "iwconfig" things look good (I think?)
| Code: |
lo no wireless extensions.
eth0 no wireless extensions.

|
But it doesn't seem to do anything useful. "netstat -rn" gives me
| Code: |
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0

0.0.0.0 192.168.0.1 0.0.0.0 UG 0 0 0 eth0
|
Amd "dhcpcd -d rausb0" gives
| Code: |
Info, MAC address = 00:13:d3:83:de:ed
Debug, broadcasting DHCP_DISCOVER
<< long pause here >>
Error, timed out waiting for a valid DHCP server response

Technical details, that might be relevant:
I have the rt73 driver. I got the latest from serialmonkey http://rt2x00.serialmonkey.com/wiki/index.php?title=Downloads.
This compiles fine; iwconfig sees the card, and if I start it up it finds my router. Only thing is the router is set to WPA (it's not mine, and I don't want to fiddle with it). I believe it would connect fine to a WEP or to an unencrypted acces point (will verify later).
But there's another version of the driver (older?) at http://www.ralinktech.com/ralink/Home/Support/Linux.html, more precisely, the first one in the list. I discovered this via a ubuntu-howto for my exact lapop (averatec 2370). The driver there doesn't seem to compile for me, but I assume (foolishly?) that my newer driver will be interchangeable. Of interest to me are the files that can be linked into the source code for wpa_supplicant to add support for this driver. Nice! It's done against wpa_supplicant-0.4.7, so I download that and compile (I tried using the latest 0.5.7 but loads of error messages).
One other thing. If I change /etc/conf.d/net to
| Code: |
iface_eth0="dhcp"
dhcpcd_eth0=""
modules=( "iwconfig" )
key_<MYESSID>="s:<MYKEY> enc open"
preferred_aps=( "<MYESSID>" )
|
Then "/etc/init.d/net.rausb0 start" gives me
| Code: |
* Starting rausb0
* Loading networking modules for rausb0
* modules: apipa arping ccwgroup macchanger macnet rename iwconfig essidnet iptunnel ifconfig system dhcpcd ip6to4
* iwconfig provides wireless
* ifconfig provides interface
* dhcpcd provides dhcp
* Configuring rausb0 for MAC address 00:13:D3:83:DE:ED ... [ ok ]
* Configuring wireless network for rausb0
* Scanning for access points
* Found "SKY15670" at 00:18:4D:01:7D:28 (managed, encrypted)
* Found "SKY15670" at 00:18:4D:01:7D:28 (managed, encrypted)
* Connecting to "SKY15670" in managed mode (WEP enabled) ... [ !! ]
* Couldn't associate with any access points on rausb0
* Failed to configure wireless for rausb0 [ !! ]
|
This is not surprising, since it is a WPA access point. I tried windoze, and it connected fine and told my it was WPA.
Are my config files OK? Meaning that the driver and/or wpa_supplicant aren't working.
Any help appreciated!
Thanks,
mike |

Just to tag a note onto my previous post, if I use the second version of /etc/conf.d/net (ie, the wireless-tools one) I am able to connect to an uncrypted WEP access point.
I haven't been able to test on any access point I have control over, but it looks like the wpa_supplicant that complies with the driver that I obtained above doesn't work. Or perhaps th fact that I am not using the driver that ships with the modified wpa_supplicant?
Comments most welcome! It would be nice to have stronger encryption available ...

From wpa_supplicant --help, i can' t see any ralink driver:
| Code: | drivers:
wext = Linux wireless extensions (generic)
hostap = Host AP driver (Intersil Prism2/2.5/3)
prism54 = Prism54.org driver (Intersil Prism GT/Duette/Indigo)
atmel = ATMEL AT76C5XXx (USB, PCMCIA)
ndiswrapper = Linux ndiswrapper
ipw = Intel ipw2100/2200 driver (old; use wext with Linux 2.6.13 or newer)
wired = wpa_supplicant wired Ethernet driver

I'm using the ralink driver (and patch to wpa_supplicant code) from http://www.ralinktech.com/ralink/Home/Support/Linux.html . This forces me to use the older version 0.4.7, since the patches don't seem compatible with the latest version.
Anyway, wpa_supplicant -help gives me the following, so I'm pretty sure that I patched it in correctly, even if the combination of driver/patch didn't actually work

Look here:
http://rt2x00.serialmonkey.com/phpBB2/viewtopic.php?t=3533
and links there given, or even search for wpa_supplicant in that forum.
I didn't tried it and not sure, if wpa_supplicant (even patched) can still/yet work with rt73. I just used iwpriv (check iwpriv_usage.txt from rt73 source archive) for wpa2psk, and it's working. |
