I have tried everything I have read about this. The problem is I can't find out what card it is. The only thing that comes up is Realtek Semiconductor Corporation. There are no name on the card. No resctricted drivers shows up.

I have tried the solutions here and from other sites. When I tried them, I get error 1 and 2.

I have managed to install the wired network, by using the suggestions found here. But every solution for wireless fails with the errors 1 and 2.

Can anyone please help me?

Here is the output of sudo lshw -C net:

And here is the reason for the error 2, I have to search to find out which one gave me error 1:

I have found out that the wireless card is called rtl8723ae.

When I looked at the homepage for toshiba, then I found that this laptop is delivered with ubuntu or windows 8. So it is a mystery that it wont work. The one with ubuntu was not available in my country.

I see from other posts that it should work in 12.04. Do I have to downgrade from 12.10 to 12.04? This is where I found that information: Drivers for Realtek wireless module for Toshiba C850-A965?

@guntbert I have updated my first post. – user66987 Jan 19 '13 at 18:44
As far as I see it, there is only one real error: the compiler complains about an undeclared identifier in line 320 of /home/kenneth/Nedlastinger/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2‌​012/base.c. That means that there is something wrong within the c-code of that module - maybe some #include ?? – guntbert Jan 20 '13 at 12:08
I don't know. Really, I don't understand any of the things I added to the question. That is why I asked for help. – user66987 Jan 20 '13 at 13:07

You should use the later version of the driver tarball named: rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012

That should fix the compile error. After the make completes, run

 sudo make install

and then check that the two rtl8723...bin firmware files got copied to /lib/firmware/rtlwifi Do it yourself (files are in the tarball/firmware directory) use sudo cp to copy them.

Better yet, use 13.04, that comes with working wireless and ethernet.
