[SOLVED] rtl8192cu wifi (32bit )

hatahata50 · 2015-12-07 00:10:44

at 64bit PC and 64bit ARCH
rtl8192cu cannot conect internet even by using rtl8192du-git .

but
at 32bit PC and 32bit ARCH
rtl8192cu can easyly conect internet by not using rtl8192du-git .

it is a interesting phenomenon .

rm /etc/wpa_supplicant.conf
rm /run/wpa_supplicant/wlp0s29f7u3
rm /run/wpa_supplicant/wlp0s29f7u4
x=wlp0s29f7u3
# ( otained by ifconfig -a )

echo 'ctrl_interface=DIR=/run/wpa_supplicant' > /etc/wpa_supplicant.conf
wpa_passphrase MyPlace   7046      >> /etc/wpa_supplicant.conf
#               （SSID)  (PASSWD)

   ip link set $x  up
   wpa_supplicant -B -D nl80211 -c /etc/wpa_supplicant.conf -i $x
dhcpcd -A $x
sleep 10
echo '----------------------------'
ping -c 3 www.google.com
ifconfig | grep 192

I can't make head nor tail of this topic. You can't connect using rtl8192du-git on 64-bit, but you can connect without using that driver on 32 bit. So what driver are you using on the 32-bit? Does that work on the 64-bit? Why is this solved? Was there ever a question?

i am poor at english .

i did read ' Realtek RTL8192CU USB wireless driver problem' , but the conclusion was not shown .
and
---->

https://wiki.archlinux.org/index.php/Wi … #rtl8192cu

he driver is now in the kernel,
but many users have reported being unable to make a connection although scanning for networks does work.
8192cu-dkmsAUR includes many patches, try this if it does not work fine with the driver in kernel.
----<

i am pleased with use rtl8192cu on arch 32bit of 32bit CPU.

i give up to use rtl8192cu on arch 64bit of 64bit CPU .
i didnot try to use rtl8192cu on arch 32bit of 64bit CPU , so i dont know whether or not to connect .

anyway on arch 32bit of 32bit CPU.

some one solves the problem to use rtl8192cu on arch 64bit of 64bit CPU .
i am also poor at rebuild kernel , so this is beyound my ability .
