Hmm… Linux can lokate my usb dongle:
ID 148f:2573 RT 2501 USB Wireless adabter Ralink Technology inc.
And it can find my IEEE 802.11bg wireless internet, but at ESSIS. there is nothing in the “” and at Accesspint: Not-associated.
What is the next step?

P.s. Sorry if it’s a stupid question but my time with Linux is so far only about 24 hours.
have you set up the connection ? are you using traditional ifup or network manager ? Gnome or KDE ?
Andy
The mention of what looks like access point, brings to mind the router setup. Your access point there needs the assigned IP on the LAN and the MAC of the dongle.
Otherwise your best approach is using networkmanager controlled in the the suse settings and leave everything to DHCP.

The question is not stupid at all.
If you have not already done so, you need to install the package
“ralink-firmware” by opening a terminal and entering the command
sudo zypper install ralink-firmware
After you have done this, you will need to unload and reload the driver using
New Connection
sudo /sbin/modprobe -rv rt2500usb
sudo /sbin/modprobe -v rt2500usb
Now, your device should be able to scan for your AP. Test this with
sudo /usr/sbin/iwlist scan
If you see your AP in the scan data, then click on the network applet in the
right-hand corner of the screen (lower for KDE, upper for Gnome), select the New
Connection entry and configure your network.
I’m using KDE and has tried to figure out how to set the connection up in Yast network manager. In the over view I see my 802.11 bg WLAN DHCP, but I don’t know where to go from there.
If I write ‘sudo zypper install ralink-firmware’ it just comes with an erroe because it can’t connect to the internet. But since Linux can see my USB dongle and has found my internet, I don’t think further installation would be nessesary.

The networkmanager down in my right corner is “not running” so I try to “edit connections” or what it will be called in english. I select “New connection” - “Wireless” and here i would love to see the programme seek for my connection, but it doesn’t.

Just because Linux can see your dongle does not mean it will work. Without
firmware, it is just a dumb device. In case you do not know, firmware is the
operating program that runs in the CPU on the dongle. All we know for sure is
that you have a driver, which runs on the main CPU of your computer.
You can see if you need firmware by entering the following command
dmesg | egrep "firmware|rt25"
and post the results. The " marks are needed in this case.
Erm,
/lib/modules/2.6.27.21-0.1-pae/kernel/drivers/net/wireless/rt2x00/rt73usb.ko
alias: usb:v**148F**p**2573**d*dc*dsc*dp*ic*isc*ip*
--
/lib/modules/2.6.27.21-0.1-pae/kernel/drivers/net/wireless/rt2x00/**rt2500usb**.ko
alias: usb:v**148F**p**2573**d*dc*dsc*dp*ic*isc*ip*
So there are two drivers for that device (at least theoretically).
The right one should be rt73usb which needs firmware, rt2500usb does not need firmware but mostly will not work with that device.
dmesg | egrep "firmware|rt25|rt73"
rpm -q ralink-firmware
ls -l /lib/firmware/rt*
First of all: Thank you all so much for helping. I really apreciate it 
Next:I made a scan (sudo/usr/sbin/iwlist scan) and the result was ESSID “3Com” (3com is my network)
Then I tried dmesg | egrep “firmware|rt25” and got: Error - Invalid RT chipset detected.
usb core: registred new interface driver rt2500usb
firmware:requesting rt73bin
So yes, there must be something missing. but the comand:sudo zypper install ralink-firmware gives me a download (curl) … and couldn’t resolve host ‘download.opensuse.org’
Now I tried dmesg | egrep “firmware|rt25|rt73”
and rpm -q ralink-firmware and ls -l /lib/firmware/rt*
Result:
lib/firmware/rt2561.bin
lib/firmware/rt2561s.bin
lib/firmware/rt2661.bin
lib/firmware/rt73.bin … aha… rt73 rings a bell.
Now what?

Post the output of
dmesg | egrep "ralink|rt25|rt73"
phy0 -> rt2500usb_init_eeprom: Error - invalid chipset detected.
usbcore:registret new interface driver rt2500usb
Registred led device: rt73usb-phyl:radio
Registred led device: rt73usb-phyl:assoc
Registred led device: rt73usb-phyl:quality
usbcore:registred new interface driver rt73usb
firmware: requesting rt73.bin

As expected, both drivers are loaded, but the “wrong one” comes first.
su
password
echo "blacklist rt2500usb > /etc/modprobe.d/rt2500usb"
modprobe -rva rt2500usb rt73usb
modprobe -v rt73usb
iwconfig
iwlist scan
Could that have something to do with the fackt that I have my usb dongle in an usb hub which is connected to my pc’s usb instead of having the dongle directly in my pc?
I wrote the code and the result after the last scan was like one I’ve had before:
The wlan0 saw the 3Com but apart of that still no access to the internet…
It’s bedtime here in Denmark and I think my husband is wondering if I have fallen asleep over the computer, so I better log off for today.
Looking forward for your reply and thanks a lot for your time today.

Have put the usb dongle direct in my pc so now the rt25 is out of the world.
So I wrote dmesg | egrep “firmware|rt73”
and the result was:
Registred led device: rt73usb-phyl: radio
Registred led device: rt73usb-phyl: assoc
Registred led device: rt73usb-phyl: quality
usbcore: registred new interface driver rt73usb
firmware: Requesting rt73.bin
So, how should I get the firmware? I tried the sudo zypper install ralink-firmware, but I get an download error.
I still don’t understand that I can scan and find my wireless connection if the problem is missing firmware for the rt73. If rt73 doesn’t work, why can I see my internetconnection?
The problem is to connect the two…
Please - I would love this to work. I would hate to give up and reinstall Windows XP

If you reread the posted messages, I was in error when I said you needed to
install firmware. Your firmware is OK. It was a TV card that was not getting
formware.
All you need to do is configure a connection. You do that with YaST if you use
the traditional ifup method, or with the NetworkManager applet if you use that
method.
Larry
Hi Larry.
Ok - sounds good. Now pleeeease help me configure my connection
I tried to do it with Network manager but I couldn’t work my way through… and I haven’t got at clue what ifup is (in danish “fup” is cheat so “I cheat” is probally not the right translation ;))
Liz
networkmanager method:
1 ) click network manager
2 ) select new connection -your wireless device
3 ) click on ESSID required
4 ) click next
5 ) make sure x is in use wireless security
6 ) select security method
7 ) type in security key,i.e. ascii,hex,passphrase
8 ) click next
9 ) click next
10 ) click save ( or click autoconnect,then save )
11 ) click network manager & select ESSID to connect to, et voila! internet 
Ifup Method: you will need to read man ifup, as there is too much to write
Andy
ditto to Andy’s advice
You might want to check you are set in Yast Network settings as Networkmanager control and not ifup.

Ifup is the name of a command - it stands for interface up.
With NetworkManager, you click on the network applet in the lower right-hand
corner of the screen. From the popup, select “New Connection” and pick wlan0.
The “New Connection” screen should show a list of all the AP’s seen. Yours may
be the only one. Click on it and then select Next. If your network is encrypted,
enter the key in the next screen. For WEP, you must use the hexadecimal key, not
a passphrase. For WPA, a passphrase is OK. Keep clicking through to the last
screen and check the Autoconnect box. Finally, click on Connect and Save.
If the New Connection screen does not show any AP’s, cancel that screen and
force a scan by opening a terminal and entering the command
sudo /usr/sbin/iwlist wlan0 scan
If this command does not show your AP, keep repeating it until you do see it. At
that point the AP should be in the New Connection screen.
If this still doesn’t work, come back and we will go through the ifup steps.
Ok…
My networkmanager in the right corner below is grey (NWM not running) so I select “edit connections” - I select “New connection” - “Wireless”.
The next screen aught to show which connections to select, but nothing is found…
So I make a scan and then I can see the connection. But still nothing found in the NWM under new Connection :\

Please post the results from the scan. To help you with the ifup configuration
file, I need more than the ESSID, which is all you have posted so far.
