[SOLVED] firmware load for rtlwifi/rtl8192cufw_TMSC.bin failed with error -2

[RodPerth]

I am new to Linux and TC in particular. I have a RTL8188CUS (Obda:8176) adapter which won't work. It is listed on the Core website as compatible with TC using rtl8192cufw.bin. This is contained in firmware-rtlwifi.tcz. Although my computer appears to connect the adapter does not become operational eg Opera tells me I am not connected.

Here are several outputs which seem to be relevant.

It occurred to me that in posting the outputs I had omitted to unplug the ethernet cable. I am now posting the "dmesg" output which does not involve the ethernet conection.

The wifi adapter still appears to connect but Opera maintains the absence of an internet connection. I hpe someone can help.

After considerable cursing and searching the forums I realised I was actually using the adapter as I had forgotten to reconnect the ethernet cable!! The adapter is working perfectly, I believe as a result of my compliance with the following advice by Juanito which I found on the TC Q & A forum.

You need to ensure the firmware extension is loaded before the wireless-KERNEL extension.

Remove them both from oneboot.lst, reboot and load them manually to test.

There is one other possible reason for the resolution of the problem. One of the posts on the forums indicated there could be a problem or conflict caused by ethernet & wifi operating together. I not only unplugged the ethernet cable but rebooted the computer and this may have contributed to the resolution of the problem.

The matter may be marked "solved". Thanks to the TC forums.

This is not exactly an error, AIUI this is normal and the WiFi should be working.
