I'm having troubles connecting to the Internet with my new wireless USB adapter. Although I can see via the NetworkManager all the wireless networks around me, it fails to connect to any of them. I'm using Linux Mint 10 RC. I've blacklisted the rt2500usb driver because it was loaded simultaneously with rt73usb.

Here is the output of lsmod:

Can somebody help me solve this problem?

Thanks in advance and best regards!

As suggested by outofstep, I downloaded the RT2501USB(RT73:RT2571W/RT2573/RT2671) firmware from http://www.ralinktech.com/en/04_support/support.php?sn=501 and copied the file rt73.bin to /lib/firmware unplugged the usb adapter, plugged it in again but to no avail. A reboot of the computer didn't help either. But thanks anyway.

This is the output of dmesg | grep rt73

Thanks for the support so far, outofstep and hhlp.

Alright, I finally established an Internet connection. And the way I fixed the problem is ridiculous: I plugged the USB adapter into one of the rear USB ports. When plugged into the front side bus the wireless networks were detected but I was unable to connect to any of them as described in my question. Also the adapter doesn't seem to work when plugged in while booting. It has to be plugged into one of the rear USB ports after start up. This is mind boggling.

Anyway, although it might seem funny: Plugging the TP-Link TL-WN321G USB adapter into one of the rear USB ports instead of the front side bus made the thing connecting to a wireless network. In what way the firmware update has contributed to the solution I can't tell. Thanks to all of you for your help.
