Hi, the problem happens either when running on battery or with the power supply. I tested with 3 different kernels: 3.11.0-12-generic 3.11.0-13-generic 3.11.0-14-generic
The last one seems the more "stable" though the disconnect are frequent. I tested also the latest v3.12 kernel (from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.12-saucy/ *not* trusty), to no avail. Actually, with the 3.12 saucy the system became extremely unstable, with crashing of network-manager at boot time and preventing also running the X server. As a stopgap measure, I'm using a small script: service network-manager stop rmmod rt2800pci modprobe rt2800pci service network-manager start that somewhat is useful to recover the WiFi support. Sometimes, when the connection drops and after a variable period of time 2 - 10 minutes, the wifi support seems to auto-recover, but in that case I'm never able to see my access points (they aren't listed in the Unity menu), but I can see "foreign" APs from neighboring offices. I still cannot connect to those APs (either because I have no credentials or because the authentication method is not WEP). I will test the 3.12 trusty kernel and report the outcome. Than you for the support. -- 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/1253997 Title: WiFi randomly disconnects Status in “linux” package in Ubuntu: Incomplete Bug description: Since upgrading to 13.10 the WiFi support has been shaky. Frequent connection drops and unstable network-manager. Only solution is a reboot, often more than one. I cannot connect to a WiFi network using authentication but WEP (any other authentication method gives instantaneous loss of connectivity).
