howto: Belkin F7D1101 with RTL8192SU from staging

[ss1979]

Hi All,

This method works perfectly on Ubuntu 10.10. Till now I have not seen any issues.

I recently purchased a Belkin F7D1101 Basic Wireless USB Adapter just to find it preforms poorly with ndiswrapper and Ubuntu does not support it out-of-the-box. Luckily, it is possible to get this chipset running natively.

1.) First I had to add the device to r8192s_usb(both files are likely empty):

Use this command in the terminal to open the first file:

and add this line:


Save it then run this command to open the second file:

and add this line:



2.) Then I obtained the firmware from here:

and copied it to /lib/firmware/RTL8192SU/ with these commands:



Afterwards, I restarted and all worked well. Perhaps others with this device will be able to get it running well too.

To expand on this process further, r8192s_usb is the kernel module("device driver") for devices with the RTL8192SU chipset. Since the module does not contain the device id for the wireless card, we use the trick demonstrated above to add it to the module without having to recompile it. This works on most distros newer than the stable branch of debian. On some like Suse, you have to install the staging package first(kmod-staging). I also had to add the firmware, dmesg is good for debugging that part. This same process can be used with other devices as long as you can find a module for the chipset and change the info in the lines accordingly.

Alternatives:
compile closed source Realtek 8192SU driver - preforms like windows xp; good signal, not very stable
use ndiswrapper with the windows driver - poor signal, not very stable

Hi friend .. i had the same issue exactly and i spend like 7houres to find out how i do the steps you did .. i didn't .. so may pleas let me know how i can do it.. i don't have know nothing about .. so i hope you can teach me step buy step .. to resolve this issue .. thank you dear

Thanks!!!!

wget http://launchpadlibrarian.net/373876...8192sfw.bin.gz
gunzip rtl8192sfw.bin.gz
sudo mv rtl8192sfw.bin /lib/firmware/RTL8192SU/

This also works on Debian 6!!

Now testing...

I can't seem to get this working under Oneiric beta 2 either. Tried the most recent suggestions as well as the older ones. AH well, time for a new usb wifi adapter!

[CTenorman]

Looks as though this bug may be getting fixed, woo hoo!

https://bugs.launchpad.net/ubuntu/ma...re/+bug/804671

Reformatting and running a quick test on Oneiric. I'd be interested if anyone can turn on the backports and proposed repositories and see if this is working for them as well.

[CTenorman]

It appears not to be working on Oneiric with all repos turned on. At least it's getting looked at!

ok i give up which wireless adapter will work with 10.4.3 out the box......?

Sorry, I should have updated sooner. RTL8192SU was dropped from the kernel some time ago and is now replaced by r8712u. This is included by default and supports F7D1101 out of the box. All you need is the linux-firmware package to supply the necessary firmware. Also, this new driver works better than the old one.
