The wifi card in question was useless to me as a result of this bug and
other driver bugginess, so as a result I yanked it from the laptop, replaced
it with an intel centrino wifi, and delivered the realtek card to Tim
Gardner on the kernel team.  Perhaps he can tell you whether it works any
better now. :)

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.
