Linksys USB54GC help on CentOS 5.3

[manimal29]

I'm relatively new to Linux and have just loaded a fresh install of CentOS 5.3 and would like to run wireles using the Linksys WUSB54GC wireles USB adapter. I cannot seem to get a definitive answer on how to get it to work. Is Ndiswrapper the way to go? How about the Ralink RT73 driver? Please, any help is appreciated. If you have configured one and go it to work, please let me know the steps/commands to do it. If you have a link to a working set of instructions, please link me to it! Thanks for all the help!

There are several versions of that wireless, each with a different chipset in it. To help you we need to know more about the device. Please read through the post linked to below. It explains how to find this information. Then post that info in this thread.

Is your wireless USB device a WiFi device, or cellular broadband modem (Sprint, AT&T, et al)? If it is WiFi, the link that waterhead gave is the place to start. If it is cellular, then you need to deal with it in a very different manner, as it is basically a USB modem and needs to be treated as such. So, let me know if it is cellular, and I will post a link to a pdf on how to install a typical Sierra Wireless Aircard.

It's a wireless-g USB adapter.

I think that the OP may have lost interest.

Doh! I didn't read his original post closely enough. I see that you are correct wh. I wonder if he has looked on the Linksys web site for Linux drivers and support. I imagine they at least have a linux "cheat sheet" to help people make it work.

Ok. After some digging, I found this link: Ralink Technology: Linux
This URL has a list of chip sets for USB wireless adapters that ralink builds, including the Linksys device you are interested it. The URL for the driver that I think you need is: http://www.ralinktech.com.tw/data/RT...mware_V1.8.zip

[waterhead]

I don't believe Linksys has "official" support for Linux. But they usually use common wireless chips that have Linux support. The problem is that they change the chips and keep the model number the same. That is why there are different versions, each version is using a different chip.

With iwconfig, this is what I get:

I have compiled and install the latest rt73 driver. In my hardware device manager, this is what I see:

I have yet to be able to get the device recognized in the network configuration tool. Any additional ideas?

That is an odd looking output of lsusb. I have never seen one that listed the driver! Did you add that?

Again this looks funny. You have TWO? wireless cards? I have also never seen a iwconfig output that listed the driver!

I have compiled and install the latest rt73 driver. In my hardware device manager, this is what I see:

Fedora has a Hardware Device Manager? Please tell me how to access it.

You didn't post all of the information that I requested. And the info that you did post, seems to have been edited. Do it again, and post ALL of the info, UNEDITED!

[manimal29]

When I get home this evening I will repost the information including anything I missed the first time. This IS NOT Fedora. This is CentOS 5.3. Yes, there are two wireless devices in the box. I DID NOT alter any of the output. The driver information IS included in the output of the command. The hardware device manager can be accessed via gui under system administration - hardware.

[waterhead]

I apologize if I falsely accused you.

I am posting from CentOS 5.3 that I have installed on a Eee PC 900. I certainly don't get the driver name for my Atheros wireless on any of the outputs mentioned. But maybe it is a Ralink thing.

If the wireless card is not showing up in the Network GUI, then it is because you don't have the correct driver for it. If you are absolutely sure that it is a Ralink wireless, then maybe you should try the latest driver from their GIT repository.

Rt2x00 GIT instructions - Rt2x00Wiki

If that is what you are using, then maybe you need to try the Linux driver that Ralink released, as suggested by rubberman.

Ralink Technology: Linux

You may just need firmware installed. That is why checking for that is one of the commands in my wireless How-To.
