Ive searched the forum and other forums but I havent been able to find any solutions. Thanks guys.

What does iwconfig show?

[fcmugen]

It doesn't even show up with iwconfig or ifconfig

[RHamel]

Well here's a linux driver.

[fcmugen]

having problems instalingl the linux driver. I have installed gcc, kernel-devel, automake, autoconf, when I run the "install.sh" script at the end I get:

make: *** /lib/modules/2.6.38.6-27.fc15.i686.PAE/build: No such file or directory. STOP. 
make: *** [modules] Error 2
Compile make driver error: 2, Please check error Mesg

If you're using kernel-PAE, then you need to install the kernel-PAE-devel package.

[fcmugen]

I installed the kernel-PAE-devel package, it did get farther but then it ended up with this

I have no suggestion on how to resolve the error you posted above.

[fcmugen]

I even installed the "Developer Tools" from the yum repos and still nothing what else I could be missing?

[PabloTwo]

Well, one suggestion: make sure you have compat-gcc-34 and compat-gcc-34-c++ installed.
I have no idea if that will help or not.

I'm running 32 bit F12 and gcc-4.4.4-10.fc12.i686. I downloaded the Linux driver from the link you posted.
After unzipping the file and then changing into the top directory, as a regular user, in my user home directory, I ran the install.sh script. An immediate "Permission denied" ensued.

I looked at the install.sh script, did a "cd driver", then extracted the *.tar.gz there. Another "cd" into the top directory created after that, then did "make". It compiled without complaint and spit out a completed "8192cu.ko" kernel module. There was no error when hitting the "..../rtl8192CU_linux_v2.0.1212.20101208/os_dep/osdep_service" during the build.

It's possible whatever newer version of gcc your running has an incompatibility with the source code for this driver, but I really can't say that for sure, rather than "missing something" that isn't installed.

[RHamel]

You need the kernel header package.

Good call RHamel, and you're probably right.

yum install kernel-headers

Note: there is no "kernel-PAE-headers", "kernel-headers" works for both PAE and non-PAE kernel installs.

I don't know what's causing that error on your system. You said you already did a groupinstall of "Development Tools". You could do the same for the "Development Libraries" group, which will bring in way more than you'll ever ever ever need, but if you can spare the disk space, there's the possibility that could bring in something that is "missing" and causing that error during make.

[fcmugen]

I am still having no luck guys I have no idea what is it... maybe the fact that Im running fedora 15?

[RHamel]

OK. Download this driver instead.

[fcmugen]

thank you guys!!! the drivers from that site worked perfectly, compiled the driver no problem thanks guys you rock!

alright as I have been using this adapter, it seems that it cuts off the wifi from the router and all my computers get disconnected from the router. What could be causing the problem?
