I can confirm that this bug still exists and have therefore put the status back to incomplete. I've been experiencing it day in and out (to my great frustration) for the past 18 months or so. The behavior is consistent across maybe 2 dozen wifi networks in equally many locations.
My wifi range and stability is still many times better in Windows than it is in Kubuntu Linux (this is a dualboot system). In many places like public libraries, where the laptop can be quite far from the actual wifi receiver, I still have good signal and multi-MB/s download speeds in windows while in ubuntu I cannot see the network, cannot connect to the network or sometimes can connect but it drops every minute or so. If I sit right next to a wifi receiver I have an excellent and uninterrupted connection for hours on end, so I'm quite convinced that generally speaking, the driver works well, but that the problem is simply a much more limited range (transmission power?) than in windows. I'm running Kubuntu Linux 13.10 with kernel 3.11.0-18-generic. My laptop is a Lenovo b570e. I hope that this bug will eventually get fixed, as I still prefer Linux as an OS but find myself needing to switch to Windows in most public locations or being the weirdy who insists on running an ethernet cable across the room because I don't have decent wifi in Linux :-/ If there is anything I can do to assist in fixing this bug, just let me know! I'd really to help this get solved but I'm completely unfamiliar with linux/kernel/driver programming. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/947697 Title: Atheros AR9285 Wireless on Ubuntu 12.04 is slow, unstable and has a weak signal.
