The title question says it all.

I've been working to answer it for my computer for the last 12 hours. I've read many articles, attempted many tricks and am more or less where I was with this problem at the start.

I won't waste breath here citing a bunch of info that may not be needed to resolve the issue, so I'll just follow the title question with this: What do you need to know about my setup, hardware, software or experience to help me (and struggling users like me) get at a solution?

Thanks in advance.

UPDATE: Jan 9

At the direction of fossfreedom I'm sharing the output of multiple terminal commands.


Command: rfkill list all

USB Adaptor: Plugged in.

Yield: Absolutely nothing. (Entered this command multiple times to make sure I was getting it right. Each time no result was returned by the terminal.)


Command: sudo lshw -class network

USB Adaptor: Plugged in.

Yield: Displays PCI (sysfs) for just a few seconds then produces the following:

Bus 003 Device 003: ID 0b38:0010 Gear Head 107-Key Keyboard

Command: dmesg

USB Adaptor: Plugged in and unplugged.

Yield: This command displays quite a bit of data. I pasted it all here--both the results from when the device was plugged in and unplugged. However, when I attempted to post the updates to my question here with all that data, I got this "Oops" message: "body is limited to 30000 characters; you entered 74516." If this info is really needed to help troubleshoot my problem, I think I'm going to need another way to post it. Or, if there is a particular line or set of lines that is most important in the results of the dmesg command, please let me know and I'll look for it and add it here.

UPDATE: Jan 9

Used the paste.ubuntu.com service for the dmesg command results. Both unplugged and plugged in results can be seen below.


Command: dmesg

USB Adaptor: Unplugged.

Yield: Pasted Unplugged Results

This command displays a lot of data. I'm not sure if the Terminal has some line limit, but it looks as if the results of this command exceeded that limit. If it is necessary, please let me know if there is some way to pause the results like dir /P in DOS.


Command: dmesg

USB Adaptor: Plugged in.

Yield: Pasted Plugged-in Results

I haven't got through each line to note any differences (not even sure what I'd be looking for), but here are the results.

  • Thank you, fossfreedom, for chiming in. But there's quite a bit of content at that link you provided. It would be most helpful if you (or anyone) can tell me directly what specifically you need me to report here. Might save a bit of guessing on my end and sifting on yours.

  • I'm sorry, fossfreedom, there must be some disconnect then. When I access the link you provided, I see at least 8 answers to one broad question. Many of those answers seem to "depend" on the situation. My situation is quite specific so I'm betting some of those answers and suggestions won't prove necessary. If you can direct me to some part of that page's content, I'd be happy to provide whatever info or logs you need.

  • plug in your usb device. In a terminal we need to see the output of the following commands: rfkill list all , sudo lshw -class network , lsusb. Also, disconnect your usb device, type dmesg - plug in your usb device, type dmesg - you should see some new output. we need to see that as well.

  • Thank you so much, fossfreedom. Very clear directions. I've updated my question with the results from the commands you cited as best I could.

  • ok - worrying that there is no response to rfkill nor lshw. Need to have a look at dmesg - please use paste.ubuntu.com and copy and paste the url into your question.

At the bottom of you trace is the following error message:

usb 2-1: new full speed USB device number 4 using uhci_hcd
    [ 3335.676636] usb 2-1: firmware atmel_at76c503-rfmd.bin not found!
    [ 3335.676645] usb 2-1: you may need to download the firmware from http://developer.berlios.de/projects/at76c503a/
    [ 3335.676663] at76c50x-usb: probe of 2-1:1.0 failed with error -2

Therefore, download the firmware file from the website: http://developer.berlios.de/projects/at76c503a/

Then in a terminal:

cd ~/Downloads
tar xvf at76_usb-firmware-0.1.tar.gz
cd at76_usb-firmware-0.1/
sudo cp *.bin /lib/firmware

Logout and login. Hopefully now your wireless card is now recognised.

  • Thank you, fossfreedom. That was most helpful. After restarting my computer the Belkin F5D6050 is now recognized. For the first time I am able to see available networks around me. Of course, this reveals a new problem. Every available network listed, including my own, shows a rather nonexistent signal strength. So I can see the SSID for my network, but I can't successfully connect to it. I find that odd, but hope it's just another simple setup step I'm missing. Like maybe my antenna is disabled somehow. Ideas?

  • Sorry for the confusion. My comment was submitted before I was finished writing. I'd say it's directly applicable since I'm still just trying to get the device to 'work' correctly.

  • ... ok - its worth playing with the router channel number 0, 6, 13 etc as well as no-security, wep, WPA etc.

    You've been awesome, fossfreedom. I think you're right and that it's an issue of capability. I'm going to call this problem solved as your great help has gotten as far as I can go with this Belkin F5D6050. Thanks for your knowledge, willingness and patience.
