Hi everybody,

I am trying out an US Robotic Wireless USB Adapter. Model number: 5423.

It works out of the box in Ubuntu Hardy. The network manager shows it as Unknown USB device, but still shows the list of available wireless networks and signal strength bars. However, I am able to log on to unsecure wireless networks without any problem. But when I log on to WPA secure network, I am unsuccessful.

I am very happy to see this USB Wifi adapter work out of the box, but it wouldn't let me log on to WPA secure networks. This card is listed to work out of the box right from the 7.10 (Gutsy) versions and also on Hardy.

Please help me guys.

Thanks a million.

Hi Guys,

I solved the problem. I installed the following drivers from:


I compiled it, installed it and followed the instructions and now my USB wifi adapter is up and running. I am successfully able to log on to WPA secured networks.

However, the only turn down is that the network manager does not show my device as US Robotics, instead shows me Wireless Networks (Unknown USB vendor specific interface). But I can live with that for the moment.

Long Live Ubuntu and FOSS.
