I was trying to set up the USR5422 USB adapter. It worked fine for the first time, but since then it freezes the computer most of the time.

What commands can I fire to see what's going on?

I followed the instructions on Ubuntu Forums thread titled How do I get a USR 5422 usb wlan adapter to work under hardy heron?

Update: It's stopped freezing, but is unable to connect to the wireless network.

My network authentication has the following properties:

  • Security type: WPA-Personal
  • Encryption type: TKIP

I've got the following settings in the linux laptop:

  • Security: WPA & WPA2 Personal

    This looks useful, if a little painful. The poster got it working well in the end. ubuntuforums.org/showthread.php?t=1838434 Oct 26, 2012 at 6:18

    Please answer your own question if you got it to work, for future reference.

  • What drivers is this using? This site claims you can use p54usb, which I believe is the prism drivers mentioned in the ubuntu forum in the comment above. Just looking to understand where this Q&A is at.

Should you wish to view the detailed information of a USB device, use lsusb

$ lsusb -d <device id> -vvv

For further USB / hardware troubleshooting, refer to the detailed answer at https://askubuntu.com/questions/235279/my-wifi-adapter-is-not-working-at-all-where-to-start-troubleshooting to get the correct driver.

From your description, the USB adapter is working but the connection fails. You might just want to try to reset your Wifi password and/or a different encryption protocol.
