How is your WiFi device listed in lsusb (that is small L, "ls" is short for list)?

Does wlan0 show up in ifconfig -a ? Some devices may not be supported by Linux due to proprietary Windows only drivers and chip manufacturer not revealing details.

have the same problem.
I have a NetGear N150 wifi dongle with RTL8188CUS chipset. (The Realtek one)
The firmware is up to date, but I can not get it working.
lsusb sees it:

Code: Select all

Bus 001 Device 004: ID 0846:9041 NetGear, Inc. WNA1000M 802.11bgn [Realtek RTL8188CUS]
but it doesn't show up in ifconfig.
and when I try:

Code: Select all

iwlist wlan0 scan
I get:

Code: Select all

wlan0     Interface doesn't support scanning.
Is there anyone else who managed to make this device work on the RasPi? If so, how? Any help would be greatly appreciated!

Hello.

Try ifconfig, ipconfig is for Windows.
