New informations about my testing: a) with new firmware the wifi connection is rock-stable at office (more than 5 hours without problem) b) at home i have changed wifi router to newer, problem is the same, tested under stable kerner and mainline (3.13.0-031300rc6-generic). sorry for long time to answer about my testing under 3.13.0-031300rc6-generic, but under this kernel my graphic card stopped working (new Intel/AMD double cards is not working out of the box in ubuntu). I'm plannig to test at home this card in windows again (if there is a big difference, or only card is lower quality than my other devices)
