[SOLVED] Modules issue

agroferia · 2012-01-18 00:10:10

First I got to say I'm sorry. I read the documentation about blacklisting a module but I have a big doubt.

When I connect my usb Wifi reciever the OS loads the following modules automatically: rtl8192cu, rtlwifi, rtl8192c_common, mac80211, cfg80211.

Those modules seem to have some kind of issue so I've downloaded the lastest compat-wireless file and installed it. For that session the OS loaded the modules I installed and all worked well. But after that, the OS in the next boot loaded the old modules from the kernel.

I read all the stuff from the blacklisting modules, but I have a serious doubt: If I'm blacklisting rtl8192cu module for example, how the OS knows it is blacklisting the one from kernel or the one I installed? Or it only blacklists the kernel modules and not the installed ones?

Thanks for your attention.

PS: The security question was funny. It got me thinking for 30secs: How I'm I suppossed to know the answer to the output of
"date -u +%W$(uname)|sha256sum|sed 's/\W//g'"

lol. Not a newbie security question.

Welcome to the forums. The security question is supposed to make people think for a second - it keeps out those pesky "non-thinkers" ;o)

I'm not familiar with the modules you list, but when those who are come along, I suspect they'll want some more info probably starting with your wireless card which can be determined by

lspci -vnn | grep -i net

Thanks for your quick answer! The modules are not the important thing. Think like if module "a.ko" is installed with the kernel, I install another "a.ko" and I want to get rid of the old "a.ko". They have the same name so I don't know if when I blacklist the module "a.ko" which the system is going to ignore.

Anyways. When I put what you said my console shows:
00:03.0 Ethernet controller [0200]: Intel Corporation 82540EM Gigabit Ethernet Controller [8086:100e] (rev 02)

But that's the network card in the motherboard...

When I do lsusb it shows:
Bus 001 Device 003: ID 0bda:8176 Realtek Semiconductor Corp. RTL8188CUS 802.11n WLAN

Which is the one is having problems.

Your package comes with a script (check_depmod), that

# Ensures your distribution likes to prefer updates/ over the kernel/
# search updates built-in

so what does a

modinfo rtlwifi |grep filename

give you as output? (it should point to the newly installed AUR module).

Well. It has been fixed , I'm not sure how. I just installed the lastest compat-wireless modules again reboot and done I didn't use the AUR package btw.

Archlinux have been one of the best linux distros I have tried. It gives you so much freedom and "pacman" is just awesome.

Arch Linux
