Title:
  8086:4238 wireless fails to send/receive data intermittently

Status in “linux” package in Ubuntu:
  Expired

Bug description:
  This did not occur with 12.10, but I am unsure of when during the
  raring release it started happening. The system appears to be
  connected, but no data gets through and you can find a series of these
  messages in dmesg.

  [17181.443299] iwlwifi 0000:03:00.0: fail to flush all tx fifo queues

  To workaround this issue currently, I use the RF kill switch to reset
  the wireless chip. My laptop is a Lenovo T410s with the Intel
  Corporation Centrino Ultimate-N 6300 (rev 35) wireless chipset.
