[Bug 1000208] Re: 10ec:8171 wifi network get disconnected periodically -- Realtek RTL8191SEvA

 

Confirming that the workaround in #75 does the trick.  Next time this
happens, I'll file a new report as in #76.  I'm not sure it it'll work
though, as I have no network then.

Title:
  10ec:8171 wifi network get disconnected periodically -- Realtek
  RTL8191SEvA

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I found a few similar bugs in launchpad history but they are at least
  3-4 years old, and I encounter this problem just after upgrade to
  12.04!

  I consulted a colleague who is a network expert, he suggested me to
  stop using wireless mouse, adjusted router settings, such as changed
  channels,  added mac address binding, stopped ssid broadcasting, just
  in case there are some hackers trying to attack my network, but to no
  avail.

  Their are still possibilities of hardware configuration, environment
  issues or hackers around my house, but the most strange thing that
  triggered me reporting this bug is that all my other devices like
  windows laptop, android phones are all OK, only this Ubuntu laptop
  having problem!

  I also attach 2 files, one is the output of a ping command so that you
  can see what happened (during the ping session I tried to let network
  manager reconnect, even if it reconnected, the network is still not
  pingable.

  Another file is syslog about the network manager.
