Please detach the ethernet cable and run and post:

dmesg | grep -e firm -e rtl
sudo iwlist wlan0 scan

It seems like you have the right driver for the right device!

christian@toshichri:~$ dmesg | grep -e firm -e rtl

Thank you.

This looks a bit suspicious:

christian@toshichri:~$ modinfo rtl8723e | head -n5
filename: /lib/modules/3.5.0-26-generic/kernel/drivers/net/wireless/rtlwifi/rtl8723e/rtl8723e.ko
firmware: rtlwifi/rtl8723efw.bin
description: Realtek 8723E 802.11n PCI wireless
license: GPL
author: Realtek WlanFAE <wlanfae@realtek.com>

However, the firmware it grabs during bootup is:

christian@toshichri:~$ dmesg | grep -e firm -e rtl
[ 21.233456] firemare: rtl8723fw_B.bin
[ 21.266038] ieee80211 phy0: Selected rate control algorithm 'rtl_rc'
[ 21.266177] rtlwifi: wireless switch is on

I wonder if that is part or all of our trouble both here and in a few other cases. I am unable to find the file in a Google search. Also, the packages I have and that, evidently you compiled, also don't contain it. The file sw.c says, in part:

173: fw_name = "rtlwifi/rtl8723fw.bin";
176: printk("firemare: rtl8723fw_B.bin\n");
177: fw_name = "rtlwifi/rtl8723fw_B.bin";
270: .fw_name = "rtlwifi/rtl8723efw.bin",
370:MODULE_FIRMWARE("rtlwifi/rtl8723efw.bin");

In fact, both firmware files and more are referenced, so this may be trivial. I've included this in my reply so I and other searchers can see it.

Which version did you compile? rtl_92ce_92se_92de_8723ae_linux_mac80211_0007.0809.2012, I hope. What version of Ubuntu are you running?

lsb_release -d

Were there any unusual warnings when you compiled?

about warnings on compile... mmmm I don´t remember ;(

[chili555]

The wireless work fine when power on the PC the first one start, but when restarted it wasn´t work...

By this do you mean it worked one time and then never again? Is the module loaded?

lsmod | grep rtl

Is there any error or warning if you load it explicitly?

sudo modprobe rtl8723e
iwconfig
lspci -nn | grep 0280

I am getting low on ideas.

[c.pfarher]

The first boot always work, but when I restart it isn't working anymore. I need to shut down the computer and then power on again for working properly

I think it is loaded:
christian@toshichri:~$ lsmod |grep rtl
rtl8723e 175717 0
rtlwifi 118776 1 rtl8723e
mac80211 540032 2 rtl8723e,rtlwifi

christian@toshichri:~$



There isn´t any error or warning if I load it explicitly:
christian@toshichri:~$ sudo modprobe rtl8723e
[sudo] password for christian:

christian@toshichri:~$ iwconfig
eth0 no wireless extensions.

lo no wireless extensions.

If the driver is properly loaded on restart, then we next suspect the wireless switch or key combination. Please reboot so it isn't working and run:

rfkill list all

Post the result here.

Let's see if we can help it start on reboot. This is all experimental, hit and miss, so we may need a couple of tries:

gksudo gedit /etc/rc.local

Above the last line exit 0, please add these three lines:

modprobe -r rtl8723e
sleep 3
modprobe rtl8723e

Proofread carefully, save and close gedit. Reboot, cross your fingers, and tell us if it has improved.
