华为3com的Aolynk WUB320g usb无线网卡芯片组应该是Ralink（它的台湾分站）的RT73，虽然Ubuntu Gutsy自带了驱动，并且识别出了网卡，但注意，这个自带的驱动不好用，或者说 没法用，仍然需要自己到http://rt2×00.serialmonkey.com/去下载开源的驱动，编译使用。（编译前后，用 iwpriv wlan0看列出的可用参数就知道这两个驱动的区别了） 编译需要内核相应的头文件，比如Linux-headers-2.6.22-14-generic，解压后按照README文件的内容：
$ tar xzf rt73-cvs-daily.tar.gz $ cd rt73-cvs-YYYYMMDDHH/Moduls $ make $ make install
