** Description changed: 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 network. - I have the Sputnik sources that shipped with my Linux installation, and - added the two PPAs as well. + WORKAROUND: sudo modprobe -r iwlwifi && sudo modprobe iwlwifi + 11n_disable=1 - I'm happy to provide logging or try some debugging steps -- please let me know how I can help. --- AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
