Rosewill RNX-N150UBE Driver doesn't work

[gtsorbo]

I downloaded the Linux driver from the Rosewill website. I followed the instructions which say:

In driver folder - uncompress the tar.gz file
then (from terminal):

• make
• ./clean
• insmod 8712u.ko

I did the make command, which created the 8712u.ko file in the driver's folder. When I attempt ./clean, I get this error:

ERROR: Module ieee80211_rsl does not exist in /proc/modules
ERROR: Module ieee80211_crypt_ccmp does not exist in /proc/modules
ERROR: Module ieee80211_crypt_tkip does not exist in /proc/modules
ERROR: Module ieee80211_crypt_wep does not exist in /proc/modules
ERROR: Module ieee80211_crypt does not exist in /proc/modules

When I try insmod 8712u.ko, that fails as well (probably because I couldn't do the previous step).
Any ideas about what the issue is? I haven't been able to find anything from Googling.

What is the version of the file you downloaded from Rosewill? What is your kernel version?

uname -r

You might be better off with a newer version from Realtek.

[gtsorbo]

I have Kernel version 2.6.31-14-generic
The driver version that I have is version 2.6.0006.20100511. There was a newer version available on Realtek's website that I just found, but i get an error when clicking the download link (brings me to a page that says I don't have permission to download this).

[chili555]

That looks recent enough. Can you please open Synaptic and confirm you have installed linux-headers-generic and build-essential? Also, please post the README as an attachment to your reply. Were there any errors or even scary warnings when you ran 'make?'

I downloaded and ran 'make' on the Realtek package and it made without a whimper on my 2.6.35-23-generic kernel.

[gtsorbo]

I have linux-headers-2.6.31-14-generic installed, but not build-essential

I get multiple warnings that say "warning: cast from pointer to integer of different size"

I attached the README

I see no instructions that give installation steps. Is there an 'Install' document included? Where did you read the installation instructions?

Strangely enough, there is no instruction at all in the package I downloaded. Silly me, I simply did:

cd Downloads/rtl8712/rtl8712_8188_8191_8192SU_usb_linux_v2.6.0006.20100625
sudo su
make
make install
exit

I believe you will need the appropriate build tools installed, i.e. build-essential.

[gtsorbo]

In the document folder, there is a powerpoint file which has instructions for installation. I converted it to PDF so I could attach it.

How should I go about installing build-essential? Since I don't have internet access on my Ubuntu machine, I can't download it directly onto that box.

[chili555]

Do you have the install CD? If so, you can drop it in the drive and do:

sudo apt-cdrom add
sudo apt-get update
sudo apt-get install build-essential

In the 'clean' file in my downloaded package, it only unloads modules that may already be loaded, so as to load the proper newly-built modules. Since you have no working wireless device, I am not surprised they are not loaded and thus aren't found in the systems list of loaded modules. I think you can safely ignore this:

ERROR: Module ieee80211_rsl does not exist in /proc/modules
ERROR: Module ieee80211_crypt_ccmp does not exist in /proc/modules
ERROR: Module ieee80211_crypt_tkip does not exist in /proc/modules
ERROR: Module ieee80211_crypt_wep does not exist in /proc/modules
ERROR: Module ieee80211_crypt does not exist in /proc/modules

Let's identify your device and see if there is an easier way. Please run:

lsusb

I'd like to see the line relating to your Rosewill (nee Realtek).

[gtsorbo]

The line is:

0bda:8171 Realtek Semiconductor Inc.

I'll try installing build-essential and post again.

This device works with the driver module r8192s_usb. I assume, since you are running Ubuntu 9.10, it's not incorporated yet in your version. Check with:

modinfo r8192s_usb

Unless you'd consider upgrading, I think compiling is the most practical solution.
