That worked!!!! Thanks for helping me out yet again, chili555!

That worked!!!! Thanks for helping

Great! Glad it's working now.

Hi.... I got a ENCORE ENUWI-NX2 and can't make it work in any way.....

Running Lucid (10.04) kernel 2.6.32-21-generic


I followed these steps http://samiux.blogspot.com/2010/05/h...sb-dongle.html (with the sudo su modification...)

but simply doesn't work

iwconfig:

sudo ifconfig wlan0 up:

Code:

any ideas???

First, let's try to fix the firmware issue. Let's see if the needed firmware is actually on your system:

Code:

sudo updatedb
locate rtl8192sfw.bin

This will take a few moments, please be patient.

You probably have the firmware in /lib/firmware/RTL8192SE. However, your driver is looking in /lib/firmware/RTL8192SU.

usb 1-2: firmware: requesting RTL8192SU/rtl8192sfw.bin

If you confirm that that's the case, let's copy over the firmware to the correct directory:

Code:

sudo mkdir /lib/firmware/RTL8192SU
sudo cp /lib/firmware/RTL8192SE/rtl8192sfw.bin /lib/firmware/RTL8192SU

Reboot and let us have your report. Include the dmesg listings as above.

Hi all, I followed this thread and many others and lost the whole week end trying to figure out how to install this ****** usb network adapter without success.
First of all: if i want to use Kubuntu 10.10 or 10.04 what USB wireless adaptor would work out of the box??
secondly: do you suggest I simply throw the Belkin Surf adaptor I have in the trash and/or try to sell it on e-bay to some windows user?
I tried everything but my computer does not want to recognize the usb adapter no matter what I do.
iwconfig says there are no wireless adaptors,
lsusb sees one belkin device and the regular usb hubs
when I try to make install something goes wrong all the time (I get a bunch of no directory, no permission or whatever messages)
Moreover, is there a way to turn the thing on or it simply turns on by itself?
when I grep the dmesg I see the usb device gets connected buy I don't see it as a network adapter..

Help

Would you please start a new thread and post:

Code:

lsusb

Send me a private message if I don't catch it right away.

Hmm. Try this way:

Code:

cd /usr/src/linux
sudo make xconfig
Device Drivers -> Stagging Drivers -> RealTek RTL8712U[*]
sudo make && make modules_install

sudo reboot

driver should load and dmesg should print:

Code:

Ok, go forward.

Code:

sudo ifconfig wlan0 up
sudo iwlist scan
sudo iwconfig wlan0 essid [type name of your wlan ssid]
sudo iwlist scan
sudo dhcpcd

Your network should be running now.
Problems I am facing now are how to force Wicd to detect that dongle.

I've added this script to ~/.bash_profile

Code:

sudo ifconfig wlan0 up
sudo iwlist scan
sudo iwconfig wlan0 essid [type name of your wlan ssid]
sudo iwlist scan
sudo dhcpcd

So each time I am login in, connection is gettin up, as you cant manage it with Wicd or network manager.


All those things were going on:
Gentoo (sorry for that, just want to help here), kernel - 2.6.37, dhcpcd 5.2.8, wireless-tools 29

Update:
Wifi-radar works fine, no idea why Wicd is slacking

It looks like a LOT of people have been similarly burned by this Ubuntu bug:
- Ubuntu Karmic 32bit Realtek 8192SU driver
- Realtek RTL8192SU driver compiling issues
- [STAGING] realtek rtl8192su chipset based USB wireless devices fail to work
- Mvix Solido driver (rtl8712/8172) on 10.04
- Firmware for Realtek 8192
etc.

To help others, here's my summary of my particular workaround to this Ubuntu bug.

I detailed my efforts to insert an external USB WiFi radio into my laptop in this thread:
- How do we tell Ubuntu 10.04 to use a DIFFERENT wireless radio card?

On my version of a pristine Ubuntu 10.04 laptop installation:

Code:

$uname -a
...
Linux library 2.6.32-31-generic #61-Ubuntu SMP Fri Apr 8 18:24:35 UTC 2011 i686 GNU/Linux

At first, Ubuntu would not recognize the Amped UA600 USB WiFi radio adapter when it was plugged into the laptop USB port.

Code:

$ ifconfig | grep wlan   
...
eth0 Link encap:Ethernet  HWaddr 00:a0:c3:3a:93:38
wlan0 Link encap:Ethernet  HWaddr 00:0a:8d:37:b3:ba

First, I determined the device identifier using 'list short USB":

Code:

$ lsusb
...
Bus 002 Device 002: ID 0bda:8172 Realtek Semiconductor Corp.

Then, in the /var/log/messages (dmesg | tail), I determined what driver Ubuntu was (mistakenly) looking for:

Code:

usb 2-1: new high speed USB device using ehci_hcd and address 2
usb 2-1: configuration #1 chosen from 1 choice
r8192s_usb: module is from the staging directory, the quality is unknown, you have been warned. <=== huh?
 ...
Linux kernel driver for RTL8192 based WLAN cards
Copyright (c) 2007-2008, Realsil Wlan
...

rtl8192_usb_probe+0x148/0x191 [r8192s_usb]       <==== NOTE: This will be useful for the modinfo command syntax!
...

usb 2-1: firmware: requesting RTL8192SU/rtl8192sfw.bin
...
usb 2-1: USB disconnect, address 3
...

Placing that keyword into "module information", I could see the desired driver:

Code:

$ modinfo r8192s_usb
...
filename:       /lib/modules/2.6.32-31-generic/kernel/drivers/staging/rtl8192su/r8192s_usb.ko
description:    Linux driver for Realtek RTL8192 USB WiFi cards
...

A quick look in the /lib/modules/2.6.32-31-generic/kernel/drivers/net/wireless directory shows an "rtl818x" directory with the following contents:

Code:

$ ls -alsF /lib/modules/2.6.32-31-generic/kernel/drivers/net/wireless/rtl818x/*
...
44 -rw-r--r--  1 root root 43176 2011-04-08 16:36 rtl8180.ko
72 -rw-r--r--  1 root root 73640 2011-04-08 16:36 rtl8187.ko

The problem appears to be that Ubuntu is looking for the following location (which doesn't exist):

Code:

$ ls /lib/firmware/RTL8192SU/rtl8192sfw_bin
...
ls: cannot access /lib/firmware/RTL8192SU/rtl8192sfw_bin: No such file or directory

The file exists (rtl8192sfw_bin); it's just in a different location on Ubuntu:

Code:

$ ls -alsF /lib/firmware/RTL8192SE
...
/lib/firmware/RTL8192SE:
total 244
-rw-r--r-- 1 root root 75984 2010-12-14 08:26 rtl8192sfw492.bin
-rw-r--r-- 1 root root 89616 2010-12-14 08:26 rtl8192sfw74.bin
-rw-r--r-- 1 root root 80976 2010-12-14 08:26 rtl8192sfw.bin

Post #35 and post #36 of this thread provided a (different sized, same-named file):
- [STAGING] realtek rtl8192su chipset based USB wireless devices fail to work



Here's what I did to obtain that differently-sized file (I guess I should call it a "driver"):

Code:

http://launchpadlibrarian.net/37387612/rtl8192sfw.bin.gz
    $ gunzip rtl8192sfw.bin.gz
    $ sudo mkdir /lib/firmware/RTL8192SU
    $ sudo mv rtl8192sfw.bin /lib/firmware/RTL8192SU/.

Finally, I was able to get Ubuntu to recognize the external WiFi radio when plugged in:

Code:

$ ifconfig | grep wlan
...
wlan0     Link encap:Ethernet  HWaddr 00:0a:8d:37:b3:ba
wlan1     Link encap:Ethernet  HWaddr f8:78:8c:a1:45:f4

Now that the driver is finally working, I can get back to the original question asked in that thread:
- How do we tell Ubuntu 10.04 to use a DIFFERENT wireless radio card?

Sort of a hijack but I think relevant. My RTL8192SU adapter (TrendNet TEW649UB)works out of the box with Natty. Great!! Until I put the machine in suspend. It'll suspend fine but won't wake up from suspend. I can unplug then replug the adapter and it will come alive and work perfectly. I have a thread about this in the Natty testing forum. This adapter suspends and resumes flawlessly in 10.10 with the firmware patch. I have an ath9k adapter and an old TrendNet TEW424UB which will suspend and resume perfectly in Natty. I'm guessing there's something with the R8712U module and I assume the 2.6.38 kernel that are not happy together. The problem occurs on a Gigabyte desktop machine and an IBM Thinkpad so it's not just one chipset that's the problem. It also occurs with Natty 32 bit and Xubuntu 32 bit. I probably should file a bug report but I'm not sure how to go about it. Apport is not activated.

I always fear updating my kernel since every time I have trouble getting my wireless card working again.

chili555, you've always helped me before some I'm hoping you'll be able to give me a hand again. I'm still running Lucid. I updated the kernel and recompiled the driver as you said earlier in this thread (which worked last time) but it didn't work. I thought maybe it had something to do with the driver being old so I downloaded the newest version of the driver and again compiled it like before but still no luck. At this point I'm stumped. I've been messing around with it for a couple hours but I can't seem to get it working. Is it possible the new and old version of the drivers are conflicting?

Thanks
