Problem with Belkin Wireless USB Card

[eteq]

I managed to get this adapter working under Ubuntu (lucid 64). Pretty straightforward actually... I got most of this from http://ubuntuforums.org/showthread.php?t=1522815 , although it required a some slight changes.

Run this command:

sudo gedit /etc/udev/rules.d/network_drivers.rules

And add this line to the file (which may be empty) and save:

ACTION=="add", SUBSYSTEM=="usb", ATTR{idVendor}=="050d", ATTR{idProduct}=="845a", RUN+="/sbin/modprobe -qba r8192s_usb"

Then run this command:

sudo gedit /etc/modprobe.d/network_drivers.conf

And add this file (and save)

install r8192s_usb /sbin/modprobe --ignore-install r8192s_usb $CMDLINE_OPTS; /bin/echo "050d 845a" > /sys/bus/usb/drivers/rtl819xU/new_id

Finally, download this file:
http://svn.debian.org/wsvn/kernel/di...rtl8192sfw.bin

and copy it to the directory

/lib/firmware/RTL8192SU/

To summarize, the first two commands tell linux to load the correct driver when that particular USB device is plugged in (which I figured out with the lsusb command), and the firmware is used to load the information the wireless chip needs to run.

Thanks a lot !
This really saved my day, and the bacon too...

Well, I've got an annoying problem when I've tried to start using my F7D2101...

I'm running 10.04 LTS and it seems it's all set up out of the box to support this device (as in all of the steps eteq outlines above have already been carried out.

Only downside is my box now crashes (no response - requires a power cycle) within a couple of minutes of booting up. Every time without fail.

So, basically, unless I can find a fix I'm stuck using a crappy old USB dongle which is also temperamental but doesn't crash my system... any ideas? I'll post the results of my dmesg when I can but it'll take a few minutes as I'll have to swap adaptors a couple of times to avoid the crash...

Here are the results of dmesg | grep 819
