That was nearly 3 years ago. I can hardly remember what I had for
breakfast.

Title:
  10ec:8172 r8192se_pci: rtl8191SEVA2 fails to transmit certain mumble
  packets

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Trying to use a new laptop with the Canonical mumble server, I have
  found that the rtl8191SEVA2 wireless card fails to send certain
  packets out.  This is shown in the packet captures I'll be attaching
  shortly: packet 23 in 'mumble-local.pcap', as well as all subsequent
  retransmission attempts, never make it to the gateway (mumble-
  inside.pcap).

  This is reproducible with both a lucid and a maverick kernel, and has
  been tested on multiple different wireless networks (with different
  routers).  If I connect the laptop over ethernet instead, it has no
  difficulty connecting to mumble.

  A cursory examination of the troublesome packet doesn't tell me what
  makes it different from other packets.  I have not noticed any other
  connection problems or slow connections that would suggest there are
  other retransmission problems, only when connecting to mumble; and the
  problem is 100% reproducible when connecting to the mumble server.
