I am missing the wlan0 interface for the wireless network.
I have an usb-adapter with rtl8192cu chipset. The led remains unlit.
First i tried the wifi-application but it shut down in silent.
Then I tried to set up wlan per wpa-supplicant.
The wpa_gui gives no adapter to choose and no networks.
installed packages are: wireless tools / wireless-3.0.21-tinycore / wpa_supplicant / wpa_gui
the driver is loaded at boot via bootlocal.sh: modprobe rtl8192.ko
dmesg gives: usbcore registered new interface driver rtl8192cu
lsusb gives: Bus 002 Device 002: ID obda:8178 Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter
ifconfig gives only: loopback and eth0
iwconfig gives: lo /dummy0 /eth0 - no wireless extensions
The adapter is functionnaly ok - it works with puppy-linux.
Any suggestions would be much appreciated - although my linux-knowledge is very limited.
I will read messages tomorrow. Thanks!

Hi
Well you need the rtl8192cu driver
wireless-3.0.21-tinycore.tcz (rtl8192cu)
Which Supports USB devices based on the RTL8188CUS and RTL8192CU chips.
Also needed is firmware
firmware.tcz (rtlwifi/rtl8192cufw.bin)
install the extensions through apps and install wifi.tcz while you are the there, no need to start via modprobe
confirm the driver and firmware loading in dmesg
-
Hi, thanks for your advice
doing as you told, dmesg shows no results / usb adapter is not detected and driver not loaded?
What now? Any idea?
-
sure, but first I think we need more information. please create and attach these files so that folks can determine your hardware
from the terminal enter
lspci -nn > lspci.txt
lsusb > lsusb.txt
dmesg > dmesg.txt
based on the comment dmesg shows no results / usb adapter is not detected
sometimes the information is missed but if this is true then there is a hardware issue. perhaps try plugging the adapter into a different USB port (ie a USB 2.0 or earlier port)
-
I'm using an IBM T23, USB has to be therefore s.th. old 1.1 version. There are two usb-slots; attached to the second usb is the mouse.
And here come the attached files...
Thank you for the commands suggested - they were very helpful and avoided messing around with screenshots and image - fiddling, which was what I thought of doing.
-
as I see there' only the last file attached
I'll give it a second try.
-
Can you reliably reproduce getting dmesg output for the card when not loading a driver onboot, but no output when you do load a driver onboot?
-
Hi,
here are the two bootscripts:
one is done while all wireless packages were removed from "onboot-menu"
and the other one is done with "modprobe rtl9192cu.ko" in /opt/bootlocal.sh
b.t.w. I remember using puppy 5.2.5 there are two network-setup programs to choose, of which one is not able to connect to wireless networks - but the other one does the job. The driver is to choose from menu (it is downloadable as an extra-pet).
-
Ok, driver gets loaded onboot (last 2 lines).
Best to boot with code "syslog", then you can leave a terminal open with
tail -f /var/log/messagesand see what output you get - if any - when plugging/unplugging device.
-
would you be so kind to explain more specificially how to boot with the 'syslog' boot option.
The bootprompt [F4] option seems not to work while
I'm booting tcl from grub4dos - is there a possibility to bind in this bootparameter e.g. after the
kernel commandline? I had one try with {cron|syslog} but no results.
yet so far there there is no folder /syslog/messages.
-
Hi che
Try appending syslog to the kernel line.
yet so far there there is no folder /syslog/messages.
That would be /var/log/messages
-
so I did reboot with:
kernel /tce/boot/vmlinuz tinycore {cron|syslog}
anyhow with plugged in / plugged out usb-adapter
there is no file added to /var/log;
the result stays the same terminal-errormessage:
tail -f /var/log: tail: read error: Is a directory
-
Hi che
Try it like this:
kernel /tce/boot/vmlinuz syslogthen this should work:
tail -f /var/log/messages
-
Hi, back again with the log
I did syslog with nothing connected to usb and whith wl-adapter only connected to it.
in the log-message done with usb_adapter_plugged_in
i presume it is line 566 where it is mentioned:
>> Jun 17 07:26:18 box user.info kernel: usb 2-1: new full speed USB device number 2 using uhci_hcd <<
as I mentioned before, it is also detected by "lsusb":
>> Bus 002 Device 003: ID 0bda:8178 Realtek Semiconductor Corp. RTL8192CU 802.11n WLAN Adapter <<
'tail -f /var/log/messages'
give the laste ten lines only, which are not of great interest, so I attached one full log-file (wl-adapter plugged to usb) in case of any interest.
The log 'without having anything connected to usb' is equal to this, except line 566, as mentioned above.
-
All of the above after having loaded driver and firmware first?
-
it is onboot.lst:
Xprogs
wbar
flwm_topside
xf86-video-savage
kmaps
graphics-3.0.3
intel-ttb
Xorg-7.6
i2c-.3.12
mirrors
alsa
alsamixergui
xfe
firmware
wireless-3.0.21
wifi
wpa_gui
wpa_suplicant
and as earlier mentioned driver loaded per modprobe
because if there is no modprobe - there is no driver
believe me I wouln't ask if this wasn't a trouble!
-
to give more compete information about which kind of adapter is used
I attach the results of 'lsusb -v'
wl-adapter and mouse are plugged in.
-
what surprises me:
This comparison might be very interesting:
I found this example in the following thread:
Re: wifi device and testing its module
dmesg | grep -i -e wifi -e rtl
example
eth%d: RTL8168C/8111C at 0xf8034000, 00:xx:xx:xx:xx:xx, IRQ 47
eth0: Identified chip type is 'RTL8168C/8111C'.

rtl8192cu: MAC auto ON okay!
rtl8192cu: Tx queue select: 0x05
rtl8192c: Loading firmware file rtlwifi/rtl8192cufw.bin
And now, how is the result if I do
dmesg|grep -i -e wifi -e rtl
I'm forced to copy it by hand from terminal - because if I use 'dmesg|grep -i -e wifi -e rtl >dmesg_wifi'
the result is pretty 'tiny' (as you see downwards)).
This is the output of the >>terminal<<
---------------------------------------------------------------------------------------------------------------------------------------
Bus 002 Device 002: ID Obda:8178 Realtek Semiconductor Corp. TEL8192CU 802.11n WLAN Adapter

iProduct 2 802.11n WLAN Adapter
-----------------------------------------------------------------------------------------------------------------------------------------
and this is the output as >>file<< of 'dmesg|grep -i -e wifi -e rtl >dmesg_wifi' :
-------------------------------------------------------------------------------------------------------------------------------------
usbcore: registered new interface driver rtl8192cu
----------------------------------------------------------------------------------------------------------------------------------------
why are these outputs different?
Now, if I compare these results with the example above - I still know nothing (because I'm just a user) - but perhaps
could it be that here is a hint to where to serch for my mysery?
-
Hmm, I couldn't spot anything missing, poking in the mist, you could try to omit connecting other usb devices like external mouse.
Also, you might get some hints if you try same radio with a different PC and/or OS and compare.
-
Seems like I will stick to puppy - curiosly but with that OS it's working.
Thank you very much for your interest and advice.
-
Hi che
Have you tried booting with the network cable disconnected or using the nodhcp boot code?
You might also try running lsmod and comparing the results between Puppy and Tinycore.
On a side note:
Why are you running graphics-3.0.3 on a 3.0.21 kernel?
-
yes disconnected boot I did, but it was of no use.
What might it be good for to boot in nodhcp when the system does not even establish an network interface?
graphics -3 I didn't really choose it because there was no other choice, but graphics was recommended with xf86.
-
Fresh boot from CD with firmware and wireless extensions and a supported realtek rtl8192cu chipset usb wl-adapter plugged in,
all I get from "sudo wifi.sh": No wifi devices found!
Hey guys this can't be true - is this really all you can offer?
No information what went wrong?
There has to be a command to get some information from that install-srcipt what was the missing information.
Come on!
-
Notice that the wireless chip you have has not been tested see here http://wiki.tinycorelinux.net/wiki:list_of_supported_wifi_devices (http://wiki.tinycorelinux.net/wiki:list_of_supported_wifi_devices) This chip was a limited edition, but still we may have a driver for it. While the rtl8712u wireless driver has undergone many updates and supports a wide range of wireless chips, unfortunately the rtl8192 driver has not.
Supported USB/WiFi adapters are cheap and in plentiful supply. I'd simply go get one that is supported, or one that has B/G or N up to N150 seems like the best choice.
I think this has been asked before, which driver and firmware does puppy use??
Also note we should never have an Ethernet cable connected when trying to connect via WiFi
-
Yes the graphics was recommended, but the version installed is not for this current kernel. Uninstall graphics-3.0.3-tinycore and install graphics-3.0.21-tinycore

Hi coreplayer2
Also where did this come from please? Your notebook?
Interestingly enough, it came from you:
http://forum.tinycorelinux.net/index.php/topic,15217.msg87827.html#msg87827

ROFL
I thought I recognized it
-
I would really appreciate if anyone would put an answer to my questions, please:
No information what went wrong?
There has to be a command to get some information from that install-srcipt what was the missing information.
-
I just tried an install of Archlinux and to my surprise wlan worked on first attempt plain vanilla auto-install menu guided from CD-boot!
Why can't TCE do the same? Such a pity.
-
TC is not a ready-to-run distribution. It is a toolkit for building systems.
Not everything is automated. You may have to do some troubleshooting and scripting to get things the way you want them.
You have been asked questions you have not answered, and asked to do things that you have not acknowledged doing.
-
It's clear we do not currently have a driver/firmware int tc-4.7.7 to support this wireless adapter. Looks like I have in my possession a similar Wireless adapter using the RTL8192CU chip, however you'll notice that for some reason this deice has never made it into the list of supported Wireless devices.
If you can provide more information on the driver/firmware used in other distributions I'd be happy to make an extension to include support for this device. Although the new TC-5.x might provide the required support.
-
Have been browsing my notes and found this which shows I might be wrong and at least we have the driver which is a good start
Your 8192cu USB wireless chip should work with
wireless-3.0.21-tinycore.tcz which contains the rtl8192cu.ko driver you're looking for.
All you need now is the firmware. I have the older version and will submit it soon. So look for
this extension firmware-rtl8192u.tcz later
Alternatively you may try the extension firmware-rtlwifi.tcz which is in the tc-5.x repo, this has the latest firmware (rtl8192cufw.bin) for your wireless chip AIUI
Pleas let us know if
wireless-3.0.21-tinycore.tcz
and
firmware-rtlwifi.tcz
work for you
if the new firmware is not compatible, I'll make the older firmware version and submit it asap
-
We have a working solution for this wireless chip available in TC-5, if you'd care to try it?
