I recently upgraded my laptop to Fedora 18. The drivers included for my card did not work. The connection light stayed on. After entering a password, it idles and then asks again. I downloaded the latest drivers from realtek and blacklisted the modules included (rtl8192cu)

However, I'm getting an error attempting to modprobe the new driver (modprobe 8192cu).

Here's the end of the script.

Compile make driver ok!!

Authentication requested [root] for remove driver:
rmmod: ERROR: Module 8192cu is not currently loaded
Authentication requested [root] for insert driver:
insmod: ERROR: could not insert module 8192cu.ko: Unknown symbol in module
Authentication requested [root] for install driver:
install -p -m 644 8192cu.ko  /lib/modules/3.7.6-201.fc18.x86_64/kernel/drivers/net/wireless/
/sbin/depmod -a 3.7.6-201.fc18.x86_64

The Setup Script is completed !

modprobe: ERROR: could not insert '8192cu': Unknown symbol in module, or unknown parameter (see dmesg)

Dmesg resuls in

[ 5598.806849] 8192cu: Unknown symbol kernel_thread (err 0)

Here's the lsusb

Bus 001 Device 010: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]

Any ideas?

It appears your kernel is newer than the one supported by the version of that driver. The driver that comes by default should work.

If you really want to use the driver you download please apply the patch found here ( you must register to download the patch.

Altough, i suggest you remove the new driver you installed, un-blacklist the rtl8192cu, and reboot.

And then show us the problems you have. Also update to a new kernel if avaiable.

Worked great for a TL-WN821N v4 on Ubuntu 10.04 with the default kernel 3.2.0-49 (no patch needed, works) and 3.9.0-030900rc6 (needed to remove the daemonize() line and apply the patch), thanks!

I wish I could but with the karma system it seems I cannot.
