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

 

Just tried that, a7x. If anything, performance actually seems worse now.

I'm now seeing close to 40% packet loss coupled with rapid, frequent
Reason 6 dissociations (the cause of said packet loss).

My /lib/firmware/rtlwifi/rtl8192cfw.bin still has the sha1 sum listed by
Pauli earlier, so presumably 'sudo update-initramfs -u' picked up the
correct firmware.

Title:
  Wireless not working in 12.04 for rtl8192ce (RTL8188CE)

Status in “linux” package in Ubuntu:
  Confirmed
Status in “linux” source package in Precise:
  Confirmed

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.
