does my rt2750USB device even work

I got this SuperPassUSB-A20 off eBay. Supposedly has 38dbm of power. It uses rt2570.ko (device ID: 0x0eb0:0x9020) which is installed OK. I used the latest "daily" driver. The "scan" function of RutilT finds the local wifi spot but won't connect.

Code:

rausb0    RT2500USB WLAN  ESSID:"<confidential>"  Nickname:""
          Mode:Managed  Frequency=2.462 GHz  Bit Rate=11 Mb/s
          RTS thr:off   Fragment thr:off
          Encryption key:<confidential>   Security mode:open
          Link Quality=0/100  Signal level:-120 dBm  Noise level:-95 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

Link Quality=0/100? That seems pretty poor.

My dinky net-book eeePC sees a 78% signal from the same spot. It won't connect either, something about "no working leases in the database". But I'm using the right key. And the link quality is 24/100.

What am I missing?

Hello,
How did you configure the stick? Did you use RutilT? Have you tried connecting through the command line?
What are the settings of the network (encryption/authentication etc...)?

Regards,
Romain

I used RutilT like I said. If by command line you mean iwconfig then yes I tried that. And ifconfig, iwlist and iwspy

Encrytion is WEP, Authentication is OPEN, Mode is Managed(according to the Link Status tab, but says Ad-Hoc mode under the RT2500USB WLAN tab), Channel is 11. And the key I got from the guy who's renting the service from his ISP.

The status is disconnected but under statistics I see that a meg or two gets received and a few hundred thousand bytes transmitted, but that's all. I can't connect to the web or even ping a url.

Ok, you should have no problem at all connecting to this network.
This is worrisome that the status is disconnected, it means that association did not even succeed.
Have you tried "shared" instead of "open" as authentication mechanism? I don't think that this can be detected through scanning, you have to somehow know that this is in use. Make also sure that there is no mac filtering, or add your stick address in the AP control interface.

Thanks for your suggestions.

I moved my 2500USB device to my net-book running the excellent systemrescuecd(no RutilT) and ran

Code:

root@sysresccd /root % iwlist wlan0 scan
wlan0     Scan completed :
          Cell 01 - Address: 00:1E:58:06:39:01
                    ESSID:"Rock-Core Mine"
                    Mode:Master
                    Channel:11
                    Frequency:2.462 GHz (Channel 11)
                    Quality=47/100  Signal level:-73 dBm
                    Encryption key:on
                    IE: IEEE 802.11i/WPA2 Version 1
                        Group Cipher : TKIP
                        Pairwise Ciphers (1) : TKIP
                        Authentication Suites (1) : PSK
                       Preauthentication Supported
                    Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s
                              12 Mb/s; 24 Mb/s; 36 Mb/s; 9 Mb/s; 18 Mb/s
                              48 Mb/s; 54 Mb/s
                    Extra:tsf=000000019a304462
                    Extra: Last beacon: 42ms ago

Is "Address: 00:1E:58:06:39:01" the "stick address" you speak of? I ran

Code:

iwconfig wlan0 ap 00:1E:58:06:39:01

but still

Code:

oot@sysresccd /root % iwconfig wlan0
wlan0     IEEE 802.11bg  ESSID:"Rock-Core Mine"
          Mode:Managed  Frequency:2.462 GHz  Access Point: Not-Associated
          Tx-Power=20 dBm
          Retry min limit:7   RTS thr:off   Fragment thr=2352 B
          Encryption key:1234-5678-90   Security mode:open
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

So, no luck. And I ran

Code:

root@sysresccd /root % iwconfig wlan0 mode shared
Error for wireless request "Set Mode" (8B06) :
    invalid argument "shared".

So, I must be doing that wrong. What's the right way, please?

The command is :
iwconfig wlan0 key restricted your_wep_key_here
Notice the "restricted" word.
