Title:
  bcmwl-kernel-source 6.30.223.248 removed, causing wireless become
  unstable on Precise

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  CID: 201103-7380

  When testing the -proposed kernel (3.2.0-88 #126), as the bcmwl-kernel-source version 6.30.223.248 was deleted on 2015 Jun. 27 [1]
  It's causing this system fail with the wireless test. I can't manually connect to the wireless network as well.

  (In the past few iterations, with the bcmwl driver 6.30.223.248
  installed, It could pass those wireless tests without any problem)

  Step to reproduce:
  1. Install 12.04.1 + proposed update on this system
  2. Install the proprietary Broadcom driver (it will be 6.20.155.1)
  3. Try to connect to any wireless AP

  Expected result:
  * Connection could be established without any problem.

  Actual result:
  * Unable to connect to the wireless network, some wl related error message could be found in the dmesg output
  [25207.998850] ERROR @wl_dev_intvar_get : error (-1)
  [25207.998861] ERROR @wl_cfg80211_get_tx_power : error (-1)
