@runnytu, @kleinph;

Modifying NetworkManager.conf get me to the fullest possible speed and the highest signal strength.

The problem with NM 1.4.2 is for a new functionality added in the new version, after upgrade both packages to 1.4.2, you need to add in etc/NetworkManager/NetworkManager.conf at the end of file this:


restart networkmanager service and works ok.

Are you using NetworkManager? That may be the problem, because it randomizes MAC addresses while scanning for networks. This seems to be not well supported by this driver and it constantly fails and spams the log with such messages:
NetworkManager: <info> device (wlan0): supplicant interface state: disabled -> inactive
NetworkManager: <warn> device (wlan0): set-hw-addr: new MAC address XX:XX:XX:XX:XX:XX not successfully set (scanning)
NetworkManager: <info> device (wlan0): supplicant interface state: inactive -> disabled

I put
in my /etc/NetworkManager/NetworkManager.conf it worked like a charm.

@runnytu maybe you could put this info somewhere.

(edit: posted the correct config snippet)

One more time, rtlwifi, rtl8192c_common and rtl8xxxu are the kernel included drivers, and rtl8192cu the provided by this package, to work with the provided by this package only is need it rtl8192cu and blacklisted the rest, if not you are using the kernel drivers and don't need this package after all, with this blacklist is working since ever, if not working maybe you need some more packages or config change but the package still working ok.

It worked. Problem solved.

I had to change blacklist-8192cu-dkms.conf from
(like comment of beef):
blacklist rtlwifi
blacklist rtl8192c_common
blacklist rtl8192cu
blacklist rtl8xxxu

blacklist rtl8192cu

works for me

after update kernel to 4.9.7-1, doesn't work for me

sudo dkms install -m 8192cu -v 1.10

Running module version sanity check.
Error! Module version v4.0.2_9000.20130911 for 8192cu.ko
is not newer than what is already found in kernel 4.9.7-1-ARCH (v4.0.2_9000.20130911).
You may override by specifying --force.


DKMS: install completed.

Change something. It no longer works. There's probably a conflict of module names.
