I'm having the same problem with my Lenovo Flex 2 with the same rtl8723be wireless card.
Kernel : 3.13.0-29-generic #52-Ubuntu SMP Wed May 28 12:42:47 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux gets the card to work. Internet works for extended periods of time, but will require the occasional reboot to get it back working. I tried upgrading to the v.3.15-rc8 I would break. I would get notification that it connected to the WiFi (DNS and all) but would never get any internet connection. Reverted back to kernel above and back in a working state - till my next reboot. Not sure if this information helps at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1320070 Title: Realtek Wifi card RTL8723BE drops connection with MSI enabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1320070/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
