HOWTO: RT61 on Feisty Fawn with WPA

[wilk]

For those experiencing the BUG CPU#0 soft lockup and its random freezes, installing the latest cvs from serialmonkey (rt61-cvs-2007051302) seems to have solved it so far. It's supposed to fix the problem with SMP-enabled kernel, which is the default with Ubuntu.

As of today, May 23, this is the only dirver I see on the website: http://www.ralinktech.com/ralink/Hom...ort/Linux.html

RT61_Linux_STA_Drv1.1.0.0.tar

Is this ok to use instead?

[jhpope]

i believe that is the one that is shipped with feisty...you could try one of the betas...i still haven't gotten my edimax 7128g working

How do i get this to work with WPA2-PSK AES? I tried to put in the paramater as WPA2PSK, but that gave some ioctl error.

For some reason, my /etc/network/interfaces keeps getting overwritten. I put in all the commands that i want, but after a reboot, i can't connect and the interfaces file has different info inside of it for ra0.

The HOWTO was most useful allowing for a couple of changes which match my system. I wanted to use WPA2 with AES encryption as that was what I had set up for my PC using that other OS that shall remain nameless. Setting the AuthMode to WPA2PSK and EncrypType to AES sorted that though and now all seems fine.

One puzzle remains though - I changed to Feisty from Dapper because I thought networkmanger did support WPA and the first time I tried to use it after a bit of playing around a WPA dialog was displayed and seemed to work fine but at that time my AP was open and I didn't want to leave it that way. When I secured it the next day and then tried to connect in Kubuntu all I could get was the WEP dialog - not a lot of use. However the fact remains the WPA dialog did appear previously, very strange. It does suggest that it should be possible to get networkmanager working properly though.

In the meantime many thanks for the help.

I thought i'd post my method. It combines a few peoples' guides here

1. Download the driver from -

http://prdownloads.sourceforge.net/r...ar.gz?download

2. Extract the driver using full paths to wherever you want

3. Open terminal and "cd" (change directory) to the "./Module" folder of the driver

4. Install the driver

$ sudo make
$ sudo make install

5. copy needed files

$mkdir /etc/Wireless/RT61STA
$cp *.bin from rt61 driver ¨Modules¨ folder to /etc/Wireless/RT61STA

6. edit interfaces file

$ sudo gedit /etc/network/interfaces

add at the bottom [editing the correct bits]

auto ra0
iface ra0 inet dhcp
pre-up iwpriv ra0 set AuthMode=WPAPSK
pre-up iwpriv ra0 set EncrypType=TKIP
pre-up iwconfig ra0 essid my_essid
pre-up iwpriv ra0 set WPAPSK="my_pass_key"

[For me i had to replace ra0 with ra1. Do an "ifconfig" to see what your install sees the card as.]

7. Reboot computer [yes you can do an ifup/ifdown but i found this more reliable]

$ sudo reboot -n

8. Sort out the routes [Sometimes i didn't have to do this. Sometimes i do. No idea why.]

$ sudo route del default
$ sudo route add default gw 192.168.1.1 [varies with router]

9. All done! Hopefully.

I am very impressed with your guide! I have been tweaking with my RT2600 and Ubuntu 7.04 for weeks, and your guide is definitely the most comprehensive.

Though I am still having some trouble;

I followed the steps up until I pinged the router, to which I get no reply. I did notice something strange.

reydrekam@SauceBox:~$ iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

ra0       RT61 Wireless  ESSID:"TheWomb"  Nickname:""
          Mode:Managed  Frequency:2.462 GHz  Bit Rate=54 Mb/s   
          RTS thr:off   Fragment thr:off

          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

You will notice my link quality is 100/00 but when I run iwlist I get:

reydrekam@SauceBox:~$ iwlist scan
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

ra0       Scan completed :

                    Quality:0/100  Signal level:-74 dBm  Noise level:-256 dBm

The quality link is 0/100

Any ideas?

I had one of the cases people having here that after all steps I was not been able to ping the router. Another result was that network interfaces file is completely messed up.

Mostly peple have dhcp therefore I would suggest instead going all the iwconfig, ifconfig, route and ping sequences you simply:

Step 1

ubuntu@ubuntu:~$ sudo gedit /etc/network/interfaces

Delete everything related to ra0 (or ra1) and around that.

Step 2

Add at the beginning of /etc/network/interfaces following:

auto ra0
iface ra0 inet dhcp
pre-up iwpriv ra0 set AuthMode=WPAPSK
pre-up iwpriv ra0 set EncrypType=TKIP
pre-up iwconfig ra0 essid my_essid
pre-up iwpriv ra0 set WPAPSK="my_pass_key"

In my case it was:

auto ra0
iface ra0 inet dhcp
pre-up iwpriv ra0 set AuthMode=WPAPSK
pre-up iwpriv ra0 set EncrypType=TKIP
pre-up iwconfig ra0 essid ZEB
pre-up iwpriv ra0 set WPAPSK="zebiekste"

*use ra1 instead of ra0 if necessary

Step 3

Reboot

I have Edimax EW-7108PCg PCMCIA Wireless Lan Cardbus adapter

Why I cannot configure for WPA, when Encryption key is on, I see Quality = 0/100
at the moment I am only able to connect to "FON_AP" access point.
