If this has been covered somewhere else that I haven't found, just link me.

I have a new Intel D525MW board, and I was going to use the Airlink 5088 Wifi-N USB adapter to connect to my wifi network. The adapter works quite well with the base 10.04 install (instructions here here ). However when I run the install script for 10.04 to install LinuxCNC, it breaks this, and it can't be installed.

The actual error I get is
make ARCH=i386 CROSS_COMPILE= -C /lib/modules/2.6.32-122-rtai/build M=/usr/src/RTL8188C_8192C_8192D_USB_linux_v3.3.2_3192.20120103/driver/rtl8188C_8192C_8192D_usb_linux_v3.3.2_3192.20120103  modules
make: *** /lib/modules/2.6.32-122-rtai/build: No such file or directory.  Stop.

I assume this is broken because of the realtime kernel change, but is there anyway to fix it? If not, do you have a good wifi USB suggestion?

Thanks!

I am sure that there is a way.
However, I gave up and used a a router in WDS mode and a wired connection from that to the PC.

Hi

There seems to be a problem with the RealTek site, I can't download the RTL8188CUS_v2.0.1324.zip

(Cancel that - just managed to get Ver 3.3.2_3192 which is what is now listed on the RealTek site for this kernel.)

I have had to compile a lot of RealTek stuff before and it usually works.
I'll have a look.

regards

Hi

Attached is the module I compiled, the driver seems to cover the range from 8188 - 8192CU

See if that works, if not you will have to install the files for a development environment, I think that was all the error was complaining about, you don't have kernel headers etc.

regards

Hi,

A bit of explanation probably required.

When I say

See if that works

what I mean is.

Unzip the module into a directory
From that directory run in a terminal
sudo install -p -m 644 8192cu.ko /lib/modules/2.6.32-122-rtai/kernel/drivers/net/wireless/
then
sudo /sbin/depmod -a 2.6.32-122-rtai

Then you should be able to run
sudo modprobe 8192cu to load it

cat /proc/modules will show it listed as loaded

sudo rmmod 8192cu will unload it

Beyond that you need to do whatever is required to use it with your adapter / card
May be nothing more than enter the line 8192cu into /etc/modules so that it is loaded at boot time, but follow whatever instructions you have for that.

regards

Thanks for that. I'll give it a try when I get back to the computer tomorrow or Monday and post back here if it succeeded or failed.

Also, yea, the new Realtek driver is the one I was using. The Ubuntu compatible hardware list is defunct now - only a seal of approval I think.
