[Bug 902557] Re: 10ec:8176 Wireless not working in 12.04 for rtl8192ce (RTL8188CE)

 

What kernel does 13.10 run?  If you want the latest, you will need to
build your own.

You also need to look very carefully at the firmware version as Ubuntu
has not been distributing the latest. On my system, the md5sum for the
correct fw is

748944fbffd3b08b5b1929bb6c7fc537  /lib/firmware/rtlwifi/rtl8192cfw.bin

The device works for me. I use openSUSE with a 3.12-rc4 kernel and I
control it with NetworkManager. I have already wasted a lot of time
trying to find what is causing problems for Ubuntu users, only to find
that the distro's firmware is out of date. I have decided to quit doing
that.

Status in “linux” package in Ubuntu:

Bug description:
  Wireless no longer seems to work since I upgraded to Precise, it was working (albeit very flaky) ion 11.10, but it never seems to be able to connect to any access points since the upgrade.
  It can see all the available networks, but it can't seem to connect to any of them.
