Hi! Some general question + Wifi USB Realtek RTL8191S

[matzi]

which location to save the *.co file?

[fvdw]

you must put the 8712u.ko file in /lib/modules/3.9.5
and then perform

Code: Select all

modprobe 8712u

[matzi]

The new driver works! :applause :applause :applause


The connection loss after unplugging lan cable is still there.

It does not successful execute the startup commands in rcS anymore. Have to do it manually in a ssh window. is there a better location later in the boot process?

Edit:
wpa_supplicant has some complaints:

root@fvdwsl-base:/ # wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B
Successfully initialized wpa_supplicant
rfkill: Cannot open RFKILL control device
ioctl[SIOCSIWAP]: Operation not permitted

Not sure if it matters?

[fvdw]

:punk

insert the module can be done in the insert-modules scipt in /etc/init.d

bringing it up should require commands like this

Code: Select all

ifconfig wlan0 up
wpa_supplicant -i wlan0 -c /etc/wpa_supplicant/wpa_supplicant.conf -B
udhcpc -b -i wlan0 -q -s /etc/simple.script

the content of the wpa-supplicant.conf should be like this

Code: Select all

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=root
update_config=1

network={
ssid="your-sid"
psk="your-passkey"
proto=RSN
key_mgmt=WPA-PSK
pairwise=CCMP TKIP
group=CCMP TKIP
}

simple scipt I attched to this post

To kill it you should use this

Code: Select all

wpa_cli disconnect
wpa_cli terminate

two questions,
does it get now an ip address ?
is it visible in your router as client on wireless network

ps running wpa-supplicant with -d option instead of -B will enable debug mode and gives lots of info what is going on

[fvdw]

about these two messages form wpa_supplicant, yes I saw these on the internet,
they monetion that we can ignore them but I am not sure. Also check dmesg I think wpa_supplicant may cause some oops errors
From what I read on the internet it seems we need to use an older version of wpa-supplicant.
I will try to compile the one included in your driver package

But at least the dongle works also with these error messages :mrgreen:

Pay attention to the last line. It does not finish - The prompt does not show up. I have to use control c to break it.

udhcpc does not work. Even when I use it manually. No lease assgigned. But may be a consequence of the missed wpa_supplicant call?

[fvdw]

in debug mode (-d) you won't get a prompt it will continue to run (it should0
When running it with -B option it goes in daemon mode and that why you get with that command the prompt.
In fact in then still runs in the background (as it should, I think)

You can open a second ssh window to give other commands.
To see the status of your dongle the command

Code: Select all

wpa_cli status

it should show wpa_state=COMPLETED
(amongst others)
if it mentions scanning then the dongle is not scanning the wireless networks, but not connected.
Then probably you have error in you wpa config file
ps be aware the ssid name is case sensitive.

also the command

Code: Select all

iwlist wlan0 scanning

is very informative it will show you what wireless networks it found...

[fvdw]

here output what I get from wpa-cli status

Code: Select all

root@nwsp2-5:/ # wpa_cli status
Selected interface 'wlan0'
bssid=00:24:01:28:ac:5d
ssid=wiel2
id=0
mode=station
pairwise_cipher=CCMP
group_cipher=TKIP
key_mgmt=WPA2-PSK
wpa_state=COMPLETED
ip_address=192.168.1.165
address=64:d1:a3:18:e5:cd
root@nwsp2-5:/ #

the fact that udhcpc doesn't work and get no lease indicates that the dongle has no connection with the wireless lan server
For that reason also the connection is lost when disconnecting the lan cable.
So I *think* you still have a connection problem (most likely the wpa conf file)

[matzi]

You were right, something went wrong with my encrypted passphrase. Corrected it and got the connection and the lease by udhcpc back. But there is still the unplug cable issue.

I have connection when I run udhcpc and manual assignment. Without manual assignment it has an ip6 adress but no ip4.

[fvdw]

how do you do the manual assignment then ?
iit should be like this

Code: Select all

ifconfig wlan0 192.168.x.y 255.255.255.0 255.255.255.255


also just

Code: Select all

ifconfig wlan0 192.168.x.y

should work. It are the commands the "simple.script" also uses. On top of that scrip adds some routes as explained by Jocko

About unplugging the cable.
If you first do ifconfig eth0 down then it won't happen. Still need to find out why that is.
The funny thing is that even with the cable disconnected the old ip it had on that is reachable. It must be via the wireless dongle. It seems the nas still response to packets for that ip number. I can stop door assigning another ip to eth0 when it is down.
So still some
