Toshiba NB500, with rtl8188ce wireless card.

Lubuntu 14.04 32 bit up-to-date. Tested with 3.13.0.32, 3.13.0.36 &
3.13.0.37.

The wifi is unstable. The connection is lost after about 30 minutes.
Reboot is needed for reconnecting.

Tried different solutions:

http://askubuntu.com/questions/456453/realtek-rtl8188ce-wireless-driver-
unstable-in-ubuntu-14-04

http://askubuntu.com/questions/414974/realtek-rtl8192ce-wireless-slow-
intermittent-access

http://askubuntu.com/questions/503763/connection-dropouts-with-realtek-
rtl8188ce

https://github.com/FreedomBen/rtl8188ce-linux-driver

The best solution (for me) seems to be:

echo "options rtl8192ce ips=0 fwlps=0 swlps=0 swenc=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo reboot

I'm testing now. It seems to increment stability but after 1 or 2 hours,
no connection.

I'm using iwevent on a terminal to control how much time it takes to
fail.

The command:

modinfo rtl8192ce

provides some information about the options for the module rtl8192ce
(used for the rtl8188ce card).

And:

systool -v -m rtl8192ce

permits to see the state of these options. For systool, package
sysfsutils is needed.

I have more than 100 netbooks with this problem. They used 10.04 and
12.04 before, without this problem!
