I have Ubuntu 1.8.10 server with X and gnome installed. I am attempting to get my USB wireless adapter working on it. Here is the output from lsusb: Bus 001 Device 006: ID 050d:705a Belkin Components F5D7050A Wireless Adapter The messages log shows the following: an 17 15:52:14 imac kernel: [14186.584008] usb 1-2: new full speed USB device using ohci_hcd and address 6 Jan 17 15:52:14 imac kernel: [14186.643967] usb 1-2: configuration #1 chosen from 1 choice Jan 17 15:52:16 imac kernel: [14187.872641] usbcore: registered new interface driver rt2500usb Jan 17 15:52:17 imac kernel: [14188.509399] usbcore: registered new interface driver rt73usb Iwconfig shows: o wireless extensions. eth1 no wireless extensions. pan0 no wireless extensions. wmaster0 no wireless extensions. wlan0 IEEE 802.11g ESSID: Mode:Managed Channel:0 Access Point: Not-Associated Tx-Power=0 dBm Retry min limit:7 RTS thr:off Fragment thr=2352 B Encryption key:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Ifconfig wlan0 up shows: root at imac:~# ifconfig wlan0 up SIOCSIFFLAGS: No such file or directory I have tried adding necessary info to /etc/network/interfaces, but no go. Wi-fi radar does not work. Ndiswrapper will not work on this architecture, and iwlist wlan0 scan does not work. The adapter works fine on my Linux Mint laptop. Any idea what steps I need to follow to get this adapter working?
