Help needed to setup wifi

[nickob]

Hi,

I do not manage to get wifi working. The dongle I use works with Raspbian, and is reported as a RTL8188CUS device. With Tiny Core, dmesg gives: "usbcore: registered new interface driver rtl8192cu". iwconfig shows a wlan0 interface, but I cannot do anything with it. iwlist s always returns "No scan result" (whereas my wifi network is up). And if I try to associate the interface with sudo iwconfig wlan0 essid "my essid", I get :

Error for wireless request "Set ESSID" (8B1A) :
    SET failed on device wlan0 ; Operation not permitted.

I am stuck here.

idk that it will work  (i donthink i have the same wifi to try)
but adding rtl firmware is worth a try

load "firmware-rtlwifi.tcz" extension
using apps or 'tce-load -iw firmware-rtlwifi.tcz'

Check the wifi related messages in dmesg (somewhere at the end) to see what is missing. You can share relevant lines here.

I could not install the firmware-rtlwifi.tcz extension: Not found. Instead I found and installed firmware-ralinkwifi.tcz, but it did not solve the problem. I looked in /lib/firmware and I saw it installed rt2xxx.bin and rt3xxx.bin files, but not a rt8188 or 8192.

dmesg gives:

....

[    3.115303] usb 1-1.2: New USB device found, idVendor=0bda, idProduct=8176

Nothing more about wifi.

Not mentioned, but probably he is using piCore 4.7

[nickob]

Yes, sorry, I use piCore 4.7.5.

Should I understand that moving to piCore 5 could be an option?

[bmarkus]

Yes. While 5.0 labeled as alpha in fact it is more up to date than 4.7 so strongly adviced to use latest 5.0.alpha6

It is interesting that it loads rtl8188cus for raspbian and rtl8192cu for TCL.  There are certainly cases where there are firmware "supersets" that can provide core functionality to a range of chips.  From what I can find (http://wikidevi.com/wiki/TP-LINK_TL-WN725N_v2), the 0bda:8176 identification indicates a Realtek RTL8188EUS chip device that requires the Linux rtl8188eu driver.  There is work under way to provide a modification to the driver for the Linux world that will allow a firmware based approach.  I hope to build on that work and hopefully add support for the 8188eu chip to the TCL efforts.

Unfortunately at the present, I think you would be better served finding another inexpensive nano USB adapter for your needs.

Since my last message I updated to piCore5.0 aplha 6 and installed the available driver extensions, but the problem is still there. I have to admit my dongle is not compatible. So bad, I have a whole batch of them!

Thanks anyway for your help.
