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

  Thread Previous • Date Previous • • Thread Next 
@Larry: I've made some debug logs from rtl8192ce module.

This is a section of it when connection is there but no data comes.

I don't know what that logs say exactly but the parity error jumps into
my eye:

  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.
