Question rt2500 wifi cards in ubuntu dapper-strange problems


Have any of you got an rt2500 chipset wifi card working in ubuntu dapper?

I have been trying to make my conceptronic PCMCIA card work in my compaq evo n110 and i am getting more and more confused.

At first i thought the only problem was i was using wpa encryption and i struggled with that for i while. Drivers (which are provided with dapper directly) seemed to be doing all right. The card was detected right away. Both an iwlist scan or GUIs (network manager, wireless-assistant, wifi-radar) detected the wireless network i want to connect to.

But after a while struggling with no results, i decided to actually change my router's security configuration to check it was only this causing trouble.

Now, when it is open, i can still detect my wireless network without problems but still won't connect. However strange this may seem, i wasn't too bothered because with no net protection, it won't work in windows xp either (but it did work perfectly with wpa).

Next try, a wep key. Windows xp does fine straight away. Now, when i reboot to ubuntu, not only i can't connect, but when trying to detect my network i get strange results. Network manager no longer detects it. Wireless-assistant does but doesn't connect. Wifi-radar does too, but with quality signal blinking on-off-on-off-... Doing an iwlist scan suggests the same, sometimes i detect the net, sometimes i don't, as if it where turning off and on all the time.

Can anyone help? If you want any further info, i will gladly hand it. For the time being, some bits of information i was asked for in another thread when i thought it was only a wpa problem:

iwconfig eth1
output:
eth1 RT2500 Wireless ESSID:"my essid"
Mode:Managed Frequency=2.412 GHz Bit Rate:54 Mb/s
RTS thrff Fragment thrff
Encryption keyff
Link Quality=0/100 Signal level=-32 dBm Noise level:-192 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

iwlist eth1 scan
output:
For the first two times i did it, i got
eth1 No scan results
Then the third time
eth1 Scan completed :
Cell 01 - Address: 00:16:38:C4:FF:58
Mode:Managed
ESSID:"my essid"
Encryption keyn
Channel:12
Quality:0/100 Signal level:-39 dBm Noise lev

Please, i need help! Thanks in advance

progress

ok, i have made some progress i think. I was manually trying to configure and still don't have access to the web, so it is not working, but for the first time ever, when doing an iwconfig eth1 i don't get link quality 0/100.

Now, wifi-radar is still doing the blinking stuff about my signal quality. Network manager still doesn't detect it. But now an iwlist scan will alwasy do.

This is what i get for a iwconfig eth1 and iwlist eth1 scan:
eth1 RT2500 Wireless ESSID:"mynetsname"
Mode:Managed Frequency=2.467 GHz Access Point: 00:16:38:C4:FF:58
Bit Rate:54 Mb/s
RTS thrff Fragment thrff
Encryption key:myhexkey Security modepen
Link Quality=73/100 Signal level=-36 dBm Noise level:-192 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0


eth1 Scan completed :
Cell 01 - Address: 00:16:38:C4:FF:58
Mode:Managed
ESSID:"mynetsname"
Encryption keyn
Channel:12
Quality:74/100 Signal level:-102 dBm Noise level:-192 dBm

Now, it bothers me a lot that what appears as the key when i do an iwconfig eth1 is NOT what i have set as key using the iwconfig key. It adds a 0 at the beginning and 12 more at the end. Is this the problem?

I have the feeling i am nearly there but there is something really simple i am not getting. Any suggestions?

it works!

It is working!!!!
Ok, not one GUI is working, but i could easily configure by hand it once i realised my key was ascii although it was very hex looking (dumb me) and i had wireless connection working! I then edited /etc/network/interfaces and now i have it on reboot. It is great! I donīt get a nice icon on my tool bar, but i give a damn. If i ever manage to make it work with wpa, i'll post how.
