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.

[Kernel-packages] [Bug 925760] Re: Constant warnings from the kernel: Test WP failed, assume Write Enabled
Me too #78. After using ss_en option, the messages changed to
continuous USB disconnected and reconnected messages.
So, finally the only solution is to disable the module as #70
recommended and wait to a fixed driver.
