Why? Because WEP encryption takes less than 2 minutes to crack. It's like leaving all your personal documents lying out on the side of the road for passersby to peak at.
Hopefully this saves someone's weekend :)
[Update: after upgrading to Gutsy I realised I forgot to mention that you should also remove the "network-manager" package - hopefully that'll help most to get things up and running.]
1) The "/etc/network/interfaces" file should look like this:
iface lo inet loopback2)
address 127.0.0.1
netmask 255.0.0.0
auto ra0
iface ra0 inet dhcp
auto lo
[Update2: I have the "rt2500-source" package installed, suspect it may provide this file that some people said they were missing -- I haven't compiled the rt2500 module from source in about a year, so the stock Ubuntu module should work, there should be no need to compile it by hand]
The "/etc/Wireless/RT2500STA/RT2500STA.dat" file should like like this:
CountryRegion=03) Reload your network:
WirelessMode=0
TXBurst=0
TurboRate=0
BGProtection=0
ShortSlot=0
TxRate=0
PSMode=CAM
SSID=ITypedMyASCIISSIDNameOutHereLikeThis
NetworkType=Infra
Channel=1
AuthMode=WPAPSK
EncrypType=TKIP
WPAPSK=ITypedMyASCIIPasswordOutHereLikeThis
/etc/init.d/networking restartYou may have to reboot to reload the RT2500 module - not quite sure about that point...

cant believe u understand this language :p
thank god for copy n paste
Assuming you're using Gnome desktop, did you have to uninstall the Network Manager applet?
hey bushmeister,
no i actually use kubuntu, but afaik it also uses the same underlying network manager code.
i would say try my solution with the applet, if it doesn't work remove the applet.
btw, network manager uses the wpa supplicant library, whereas rt2500 goes its own way -- that's why network manager messes things up.
if you have any more questions i'll be happy to have a go at answering them.
Hi John,
I've been tinkering with this for a good while now, and still haven't got my card to do WPA.
I followed your instructions but I think you must have missed out some preliminary information. I didn't have a "/etc/Wireless/RT2500STA/RT2500STA.dat" file at all, so I made one and copied yours (with obvious changes for SSID and passphrase). In fact I didn't have a /etc/Wireless directory at all. So, I'm wondering whether you first did something like install and compile the RT2500 driver from source?
Or did you use the newer RT2x00 driver?
hey bushmeister,
well although at once stage i did compile my drivers from source, that was well over a year ago and i've done mutliple kernel updates sine then.
i'm on hols at the mo, i know how frustrating it is -- once i get back i'll check up on my setup again, and see if i forgot to mention something.
hopefully, u'll eventually figure it out!
Hi John,
Do you remember if you had to do anything special to get the card working initially? My card used to work in edgy, but it looks like it broke with feisty.
Thanks,
Casey
hi casey, not as far as i know - i basically just did what i described...
i am really worrying about the upgrade to gutsy - linux shouldn't be like this, should it!!???
