No wireless after 12.10 installation

[colmeweb]

Hey everybody,
I just installed Ubuntu 12.10 on a toshiba satellite c850d that had Windows 8 pre-installed. For some reason there is no sign of the wireless in the top panel or in the network settings. I have been poking around but haven't found anything that works yet. Below is the output from lspci -nn | grep 0280. Any help would be great, Thanks.

colin@colin-Satellite-C850D:~$ lspci -nn | grep 0280

Your wireless card is a Realtek 8723.

Hey Abhinav I followed those steps but on the last one (sudo modprobe rtl8723e) I got

root@colin-Satellite-C850D:/home/colin/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012# sudo modprobe rtl8723e
FATAL: Module rtl8723e not found.

I tried it without the e and go the same response, any advice.

I believe in later versions of the driver it is renamed. Please try:

sudo modprobe rtl8723ae

[colmeweb]

Nope rtl8723ae not the answer

How long does this take? After I went through the sequence I tried to close the terminal and it said that it was still working. Also there is a # sign after the ~ that I haven't noticed before.

The little # means you are running as root. The terminal is complaining about closing because when you issued the command 'sudo su' you asked to run some commands as root, also known as super-user. The terminal wants to be sure you are done. You could and should tell it you are done with:

exit

Then the terminal will close without complaint.

Nope rtl8723ae not the answer

Please go through the compile process again and see what module it builds at the end of 'make', like this:

It will be rtl87-something-.ko. Modprobe the module without the .ko extension. If 'make' ended in an error, the module never actually got built. Post the error(s) here and we'll troubleshoot.

Hi colmeweb,
Sorry for the late response. Now the real doctor chili555 is with you.

And Thankyou chili555 for joining this discussion.

Let's load the module and see if there are any complaints:

sudo modprobe rtl8723ae
dmesg | grep rtl
ls /etc/modprobe.d

Thanks.
