[Bug 1091372] Re: wifi slows and/or drops frequently


I'm having the same problem with my Linux Ubuntu 12.04. At work it seems
to stall and the internet cuts out, even though I'm still connected to
the router. The problem is temporarily fixed if I disconnect and
reconnect to the router. At home the same thing happens, but it asks me
for the password even though it's already saved. I've had the computer
for 2 weeks now and everyday it gets progressively worse, which is
extremely frustrating with my job being web development.

I can provide system logs and wireless info if needed.

On a side note, I was extremely wary about getting a Dell vs a Macbook
Pro, but a coworker convinced me to try this out as it was "perfect" for
development work. I had a horrible experience a few years ago on a Dell
laptop that completely fell apart. So it's safe to say that if this
problem isn't fixed soon, I'll more or less forever lose confidence in

  wifi slows and/or drops frequently

Status in Dell Sputnik:
Status in “linux” package in Ubuntu:

Bug description:
  I received my Dell Sputnik XPS (12.04) three days ago, and since then
  have experienced very unreliable wifi. I'm seeing significant slow
  downs and drops on several networks.

  Two main issues:

  1) Wifi slows down significantly for 10-60 seconds. It appears no
  packets are getting through, as all browser requests churn, Flash
  games show connection errors, pings don't work, and Software
  Center/Update Manager/apt cannot connect. The connection always
  returns eventually. This is happening once every few hours to many
  times an hour.

  2) The wifi connection disconnects and quickly reconnects. This is
  also happening between once every few hours to several times an hour.

  I cannot spot a pattern or a trigger, but it's happening a lot. It's
  occurred on all three networks I've connected on. Two were standard
  secured home wireless networks, and one is a corporate wireless

  I have the Sputnik sources that shipped with my Linux installation,
  and added the two PPAs as well.

  I'm happy to provide logging or try some debugging steps -- please let me know how I can help.
