I had this problem with a relatively weak signal. NM would do it's scanning for better networks and loose the connection in the process.
Two things fixed the problem for me: (1) Use the windsurfer signal booster on my router http://www.freeantennas.com/projects/template2/index.html (2) Disable the roaming and configure the WiFi manually. Since then connection is rock-solid. Note that due to a bug I have to re-enter the manual configuration after each reboot. -- NM disconnect Wi-fi Lan after some time https://bugs.launchpad.net/bugs/203442 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
