View Full Version : [ubuntu] USB-N13 Ubuntu 10.10

I have spent a few hours trying to get my new USB-N13 wireless Adapter working with Ubuntu and I am really still struggling. If I do an iwconfig I get the following:

lo no wireless extensions.

eth0 no wireless extensions.

ra0 Ralink STA ESSID:"linksys" Nickname:"RT2870STA"
Mode:Managed Frequency=2.442 GHz Access Point: 00:25:9C:D9:A1:9F
Bit Rate=130 Mb/s
RTS thr:off Fragment thr:off
Link Quality=71/100 Signal level:-68 dBm Noise level:-82 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0
Which tells me Ubuntu has found the USB Adapter. For whatever reason I can't configure this using the Network Manager. If I manually configure the adapter by doing

iwconfig ra0 essid linksys
I can connect, but if I restart those settings are lost. So first question, why does this not show up in network manager for me to configure, and second question why can't I access anything beyond my router? Second question, if I can't get network manager to work how can I set this up to work with my WPA enabled router (currently encryption is off to test things)?

If there are additional lines except lo interface lines, they are not handled by the network-manager.

To access the outside world you must probably add a route.

sudo route add default gw x.x.x.x ra0

To encrypt use the key option in iwconfig. See man iwconfig

Not sure I follow what you mean by:

If there are additional lines except lo interface lines, they are not handled by the network-manager.

a bit of googling led me to this page (http://everyjoe.com/technology/howto-use-iwconfig/) as an example of how to use WPA Supplicant...I'll have to try this.

Ultimately though I'd like this all handled by network manager, how can I do this?

Which driver are you using for this adapter?

I downloaded the latest driver from ASUS and compiled it. In the readme file, it says to make sure 'HAS_WPA_SUPPLICANT=y' and 'HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y' are set in the ./os/linux/config.mk file to allow NetworkManager to work.

I'm running 10.04 Lucid and the adapter didn't work out-of-the-box, which is why I installed the driver. I don't know if this is the case in 10.10.
