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'.
iwlagn: Intel(R) Wireless WiFi Link AGN driver for Linux, in-tree:
iwlagn 0000:06:00.0: Detected Intel(R) Ultimate N WiFi Link 5300 AGN, REV=0x24
rtl8192cu: MAC address: 00:9c:91:99:c4:88
rtl8192cu: Board Type 0
rtl8192cu: rx_max_size 15360, rx_urb_num 8, in_ep 1
ieee80211 phy0: Selected rate control algorithm 'rtl_rc'
usbcore: registered new interface driver rtl8192cu
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
   idProduct      0x8178 RTL8192CU 801.11n 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   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

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.
