I'm also using Ubuntu, Saucy: "Linux desktop 3.11.0-7-generic > #13-Ubuntu SMP Tue Sep 10 20:55:38 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux". --snip-- > > Let me know if there is anything I can do to help There is a known problem with the dynamic power management code for this chip. Unfortunately, the problem does not affect my system. At the moment, my device that uses rtl8192cu has been connected for 12 hours with no disconnects. The only evidence of a bug here is poor performance. Please describe your setup. What AP are you using? Is it an 802.11n or an 802.11g connection? How far is your station from the AP? Are there any obstacles such as walls in the way? What is the signal strength as shown by iwconfig? Larry
