View Full Version : [ubuntu] Problem with new USB wireless adaptor

I am trying to configure my new Wireless card. The only name I can find is on the installation manual "Ralink". It came with a installation CD that also will not work, at least not right away. The installation CD are made for Windows, Mac, and Linux included.

Ubuntu often recognise different hardware right away, but not this one. When I connect wireless adaptor to computer, nothing is detected. When I use the installation CD it will not "unpack" and the wizard that are suppose to appear does not.

Any Ideas?

I also have a ralink-powered card, and it works just fine out of the box :)
What's your kernel version? The module should be included, maybe you miss the firmware for license issues. Post


find /lib/firmware/ -name 'rt*'

If it outputs something, then try plug off/in your card and post


dmesg | tail

After a reboot and plugging USB wireless in and out a couple of times it is detected, but it's not active, no networks detected. My laptop has the original inbuilt network still in place, but the reception is rather low in that card. I was hoping that the USB wireless would have better reception since it has an antenna. My PCMCIA wireless card is working all right.

If it is a reception problem there's nothing you can do :(
Also my card suffers from this problem. I totally solved (ubelievable) with a "cantenna" :) which raised up my signal strength from 0 to 70%!!! But mine is a desktop machine; if you have a laptop I doubt you can do the same
Also your PCMCIA has an antenna, I guess ;)

My fault

I don't know if you can make any sense of this. I don't know if reception will get any better, but the USB wireless card should at least work? It has a antenna input with standard plugin, and it can take any ordinary wireless antenna that a stationary computer use. However, the reception is not the main problem, it is making it work at all. Sorry about making such a fuzz about it.

It's a bit strange. When you plug the card


[18774.090519] udev: renamed network interface wlan2 to wlan9

but in the last post there's no wlan9 (wlan2 neither). I guess you rebooted, so you should repeat the key-steps to get your actual wlanXXX (namely plug off/in, then `dmesg | tail | grep wlan`. Then you should get your device name, so you can `sudo iwconfig wlan<N>`). Anyway it seems that the kernel side is Ok. What wireless GUI do you use? NetworkManager? WICD?

I'm not shore if I give the correct answer, but I use Network Manager. (When I right-click wireless icon on the top-line application bar, then "about" I get "NetworkManager Applet 0.7.996").

I have three network cards on my laptop when the new one is plugged in, the working PCMCIA card, and the original in-built. The reason for new wlan numbers might be because I did plug and unplug them to see if anything happened.

I think you have to disable the cards that is not in use. ifdown wlan<N>

I have been struggling with my new USB wireless card for some time now. I have looked up different threads and Ubuntu wiki pages, but still stubbornly difficult.

I tried to follow this (http://ubuntuforums.org/showthread.php?t=1285828) among them, but it's too advanced for me, I get too many error messages that I can't fix. This is an instruction on how to down load the drives from the Ralink-site and add it to the active driver list, but it's just straight forward.

When I bought this card I was under the impression it came with a wizard installer for the drivers, but it doesn't work. I seriously contemplate buying a new one, but I want one with antenna input, and there's not that many available.

It there another way around this? I would love to find the drivers in some kind of package or version that install manager takes care of.

Anybody who are willing to take a look at this?
