[Solved] Have to modprobe my wireless card every boot and frequent dropouts

[Ozdemon]

I have recently purchased an Asus USB-N13 wireless adapter. I have two problems:

(1) I have kernel 3.2.18 installed in the Gnome version of PCLOS. I have installed the driver from the Realtek site. The chip - RTL8192cu - is listed in /etc/modules and also shows up in the PCC Hardware. The first problem is that the wireless doesn't work after a restart. If I enter the following in a terminal (as root), it comes up straight away:

Code: [Select]

# modprobe -r rtl8192cu
I don't understand why I have to do this.

(2) It keeps dropping out. When it drops out I have to modprobe again. When it is working it shows a signal strength of 90% or more, so I don't understand why it keeps dropping out. The adapter is supposed to be linux compatible.

If I enter the following in a terminal (as root), it comes up straight away:
Code:
# modprobe -r rtl8192cu

So it works when you remove the  rtl8192cu  module.

Maybe you should blacklist the module and thus prevent it loading. See   /etc/modprobe.d/   for a blacklist file.

What module did you install from the Realtek site?

Thanks for the reply. The driver I installed was from http://tinyurl.com/yj3jvnk, specifically the RTL8192cu, which, now that I look again, says it is for Linux Kernel 2.6.18~2.6.38 and Kernel 3.0.8.

BTW, I only installed the driver after having the problem of the adapter not working or working then dropping out. I will try the blacklisting but I suspect I will be back where I was to begin with.

Well, the blacklisting worked although I have no idea why. 

I don't need to know, the main thing is it works, thanks.

YW ......  the 'now blacklisted' driver was loading and being used by the device which prevented your installed driver from being used. Blacklisting the driver prevents it being loaded allowing the installed driver to be used.

Glad it is working for you

Wow, it is amazing what advice you can find in these forums!

I was having the same sort of problem.

I have a Tenda W311U USB wireless dongle that I have been using for some
time with 32-bit PCLinuxOS. When I cut over to 64-bit the
wireless connection would drop all the time. Very annoying!

I also have a Realtek micro wireless USB dongle that I got
drivers Linux drivers for, but could never get it to work.

The solution was to blacklist the built-in rtl8192cu driver
and let the newer, vendor supplied 8192cu driver load!

Don't know why rtl8192cu did not work, but then again
now I don't really care.

The Realtek with 8192cu works a treat and has not dropped
once in 2-3 days.  Needless to say the Tenda has been retired.

Many thanks to all!
