Hi! Some general question + Wifi USB Realtek RTL8191S

[matzi]

To establish a connection I still have to do two things:

First:

root@fvdwsl-base:/ # udhcpc -i wlan0
udhcpc (v1.21.0) started
Sending discover...
Sending select for 192.168.178.24...
Lease of 192.168.178.24 obtained, lease time 864000

I know I omit the simple script this way, but with it it I found no difference. An the first call including simple script is still in the startup script. I am not sure if is already executed during startup.


Then I use the IP displayed from udhcpc command and us it like this:

ifconfig wlan0 inet 192.168.178.24

This creates no output. Now I can connect to the webinterface under the wireless IP.

[matzi]

I amanded the output of the udhcpc command in the bootlog file. It clearly shows that a leas is obtained on booting. The missing thing is the assignment to the interface.

[fvdw]

for that you need to use the "simple.script"

but basically this script gves the command I posted above to set the ip address of the network interface

ps did you set the sript with executable permissions ? (chmod 755) if not then it won't run..of course

[matzi]

I am such a newby!

Thanks that's it. :hail

Now hopefully you can solve the unplug issue and we're fine!

[matzi]

By the way - can i use the kernel on SPD8020 as well?

[fvdw]

no this kernel can not be used on spd8020

ps I will sent you by pm a new driver, found some bugs in the previous one. To test it.
Also I took out some code making it very verbose in dmeg output, I think if you check dmesg output you will see many message. Most of them are usuless for normal operation and more for debugging. Don't know why the programmers left it in.
Also I compiled wpa_supplicant-0.6.9 as it came with your driver, need some patching to get it work with linux-3.9.5 and newer version of libnl
That version of wpa_supplicant will not give the two warning messages that 2.0 does with this driver.
But wpa-supplicant 2.0 seems to work also ok despite these messsages. Anyhow you can try to see if there is a difference

[matzi]

Error messages from wpa_supplicant are gone.

dmesg is as follows It's different, not sure it's shorter (missing out the first part up to time stamp 9.37...)

mmm...
still a warning in this part, no idea yet what it means, so to see it comes from wpa-supplicant letting the driver doing something it doesn't like

My congratulations for the interesting developments!!!!

I think it's a really nice feature add a USB wifi to our nas!

good job!

[matzi]

Found something interesting about the "unplug cable" issue. Running a port scanner on another computer in the local network shows that traffic through eth0 and wlan0 have the same mac adress. That means that wlan0 is not really in use i guess. Then i used "ifconfig eth0 down" and sanned again the remaining ip. This time it shows the correct mac adress of the wifi adapter. Strange isn't it?
To me that explains why the connections break by simply unplugging the cable. It disconnects the one and only route which just has two names.

Now that's the anamnesis, but what can be the treatment?

Edit: "ifconfig etho up" reassigns the old mac to wlan0
