Thanks. The data is a little incomplete as some of the wireless frames don't seem to be passed up from the driver, but what I do see (excessive amounts of frame retransmissions) seems to indicate that your wireless adapter has difficulty communicating with the APs. The problems themselves are probably at the RF or firmware level, but they might be caused by suboptimal configuration of the driver.
Unfortunately the Realtek wireless drivers are community supported, and as far as I know there's no publicly available documentation. There's a couple of things we can try though. The easiest is to test the recent 3.14-rc1 kernel to see if any issues have been fixed there. There's a build available at http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.14-rc1-trusty/. The other option is to try the out-of-tree driver from Realtek to see if it performs any better. This driver is available at http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true (you need the driver for RTL8188CE). If either of these give you better results we can try to work out what needs to be changed. -- 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/1276238 Title: Wifi Connection Dropping/Need to reconnect Status in “linux” package in Ubuntu: Incomplete Bug description: While connected to wifi, my system will randomly drop the connection and ask me to reconnect.
